Full textAbstract:
<p>Background: The wireless technology Bluetooth has rapidly become more commonly supported by electronic devices like mobile phones and PDAs. Several companies are currently developing Bluetooth broadcasting systems to use for marketing. This report is a result of researching the use of Bluetooth broadcasting for delivering information for more general purposes, how well Bluetooth actually works for broadcasting, and also on the topic of user privacy. Results: Broadcasting with Bluetooth did work with a few devices at the same time, since Bluetooth allows up to seven connections to one Bluetooth radio at the same time. By making a passive system where the user is the one which requests information, it also will not affect users' privacy. However, my research also found a few issues with the Bluetooth which might affect a broadcast, the most noticeable of them being the somewhat low transfer rate, an issue with device discovery not always working when a lot of users are doing device discovery at the same time. The fact that it only supports seven connections is also a limitation. Basically, while it is possible to use Bluetooth for broadcasting, it might be problematic to use it for targeting a large audience. Conclusions: Even with the problems mentioned, Bluetooth broadcasting provides quite a unique way of broadcasting, and with the newer versions of Bluetooth the issues mentioned might be less of a problem. Bluetooth broadcasting definitely has some potential.</p>

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2000.<br>Also available online at the DSpace at MIT website.<br>Includes bibliographical references.<br>Bluetooth is the codename adopted by a consortium of wireless equipment manufacturers that is working toward a low-cost, global standard for wireless communication of data and voice. It will operate in the unlicensed ISM band (industrial, scientific, and medical) with gross transfer rate up to lMbps and it will connect devices within a range of 10 or up to lOOm. The benefits of Bluetooth technology are twofold. First, it enables a user to replace the various cables between devices with a universal short-range radio link. For example, a cellular telephone and a portable computer equipped with the Bluetooth technology can interface without the need for cables. Further, they could interoperate with similarly equipped devices such as printers, fax machines, desktop computers and peripherals, and a host of other digital devices. The second major benefit of the Bluetooth technology is its ability to provide a connection between the ad hoc network and existing data networks. Bluetooth technology is designed for wireless personal area networks (WPANs), which are networks of personal electronic devices in close proximity to each other. Expectations for Bluetooth technology are that it will become a major player in the wireless data communications market, due primarily to its simplicity and its support from large companies, many of whom are integrating the technology into their products. Further, Bluetooth members are encouraging vendors to incorporate the technology into their products by waiving intellectual property royalty fees. That being said, this paper will explore the technical aspects of Bluetooth as well as the strategic rationale behind the founding companies. Since e-commerce might be heavily affected by this technology, especially business-to-consumer and consumer-to-consumer, this paper also explores the impact and possible changes in consumer and merchant behaviors.<br>by Ralf San Jose.<br>M.B.A.

Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth och några allmänt tillgängliga attack verktyg. Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta avstånd. Därför har man valt att implementera det i kommunikationsenheter som mobiltelefoner och laptops med mera. Det har funnits en debatt om hur säkert Bluetooth är. För att kunna genomföra denna undersökning så har vi satt oss in i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och implementationer av dessa, som finns. Vi har även testat några implementationer av de funna attackerna. I vår undersökning testade vi nio attackverktyg mot en implementation av den senaste version av Bluetooth. Värt att tänka på är att vi inte vet om de finns andra attackverktyg som fungerar på dagens Bluetooth-teknik. Vi kan fastställa att det är säkert ifall du följer de säkerhetskriterier som vi presenterar.

Jonsson, Björn. "Bluetooth QoS Scheduler." Thesis, KTH, Mikroelektronik och Informationsteknik, IMIT, 2003. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-93114.
Full textAbstract:
Bluetooth is a low cost, short-range radio technology that enables electronic devices to communicate wirelessly via ad-hoc networks. Different kinds of applications may run over these networks, some of these applications with particular Quality of Service (QoS) requirements. One such application could for instance be an Audio application which need data frames to be delivered at regular interval to work properly. The communication over Bluetooth links is totally controlled by one of the participating nodes. Since this node controls the traffic and thereby controls the QoS within the network its communicating behaviour is of great importance for maintaining QoS reservations. A central part in maintaining QoS reservations is the scheduler, which prioritises between different tasks to be done such as which device that is allowed to transmit next. There is no standardised way to implement the Bluetooth scheduler. However, a Bluetooth scheduler should be able to handle QoS reservations, maintain fairness among the participating nodes, and utilise the available bandwidth efficiently. Furthermore a key requirement in Bluetooth is simplicity, therefore a Bluetooth scheduling algorithm should be of low complexity. This master thesis presents a new patented solution for an intra-piconet scheduling algorithm that is capable of maintaining QoS reservation, while being fair and also meet the low complexity requirement. This algorithm is presented in detail in the thesis and has been implemented in an ns2- based Bluetooth simulator. Simulations in this simulator are presented that verifies the scheduling algorithms functionality.<br>Bluetooth är en standard för trådlös ad-hoc kommunikation. Denna standard definierar i antalet noder begränsade nätverk (piconet) som kan kopplas samman till större nätverk (scatternet). Många olika typer av applikationer kan tänkas använda dessa nätverk, vissa av dessa med speciella krav på Quality of Service (QoS). Ett exempel så en dylik applikation är ljudöverföringar som kräver att data överförs med jämna mellanrum för att kunna fungera tillfredställande. Kommunikationen över ett Bluetooth-piconet kontrolleras helt av en av de deltagande enheterna. Eftersom denna enhet kontrollerar trafiken kontrollerar den också upprätthållandet av QoS reservationerna. En central del i detta upprätthållande är schemaläggaren, som är den del i en Bluetoothenhet som prioriterar mellan olika saker som ska utföras. Ett exempel på en sådan prioritering kan vara vilken enhet i nätverket som ska få kommunicera härnäst. Bluetooth standarden beskriver inte hur denna schemaläggare ska implementeras. Grundläggande krav på en Bluetooth schemaläggare är att den ska kunna hantera och upprätthålla QoS reservationer samtidigt som den delar den befintliga kapaciteten på ett rättvist och effektivt sätt mellan de deltagande enheterna. Vidare bör den ha en låg komplexitet eftersom enkelhet är ett krav på alla delar i ett Bluetoothsystem. Detta examensarbete presenterar en ny patenterad algoritm för schemaläggning i begränsade Bluetoothnät som är kapabel att upprätthålla QoS-reservationer, samtidigt som den distribuerar den tillgängliga kapaciteten på ett rättvist sätt. Algoritmen möter också upp till kravet på låg komplexitet. Rapporten innehåller vidare simuleringar av algoritmens funktion, dessa har utförts i en ns2-baserad Bluetooth miljö och verifierar algoritmens funktionalitet.

Full textAbstract:
Detta examensarbete gick ut på att enligt utvecklingsprocessen på Motion Control utveckla en prototyp av en kabelersättare för en produkt på företaget; USB I/O. USB I/O är en mät- och styrenhet och datainsamlingsenhet för USB-porten med flera in- och utkanaler som i flera applikationer har som nackdel att den är kabelbunden. Tanken var att göra en enhet som man ansluter USB I/O till och som kan kommunicera direkt med konventionella ”Bluetooth-dongles” som är vanligt förekommande på konsumentmarknaden.Tre undersökningar gjordes. Den första var en marknadsundersökning för att se lämpliga systemkoncept samt vilka konkurrenter som kan finnas. Denna undersökning visade på att det inte fanns många produkter på marknaden som var nära det sökta konceptet. Efter detta följde två undersökningar, vilka hade som syfte att göra lämpliga val av kretsar till prototypen. Halvvägs i examensarbetet upptäcktes att oavsett val av Bluetoothmodul, skulle den kräva en modifiering av Bluetoothprofilen HID för att kunna använda vanliga ”dongles”. Detta skulle ta mycket längre tid eller kosta mer än projektbudgeten tillät. Utifrån detta valdes att planera in utveckling av ytterligare en enhet som ansluts till datorn, för att ersätta ”dongeln”.Examensarbetet resulterade i en prototyp bestående av två delsystem färdiga för vidareutveckling. Funktionstester där USB I/O kunde trådlöst anslutas till en dator med systemet visade på att delar av den sökta funktionen uppfyllts, men en stor del utveckling kvarstod.<br>This thesis work had the intention to acoording to the processes of Motion Control develop a prototype of a wireless cable replacer for an existing product, USB I/O. USB I/O is an I/O and data collection unit with a number of in- and outputs. It has in some applications the drawback that it is connected through a USB cable. The idea for the work was to create a unit to connect to USB I/O which has the capability to connect to any existing “Bluetooth dongle” on the market.Three investigations were made. The first was a market investigation to see potential system solutions and to find out any direct competitors. It showed that the existing market did not offer any large number of active similar products. After this, two investigations were made to find suitable components for the prototype. Half way in the thesis it came obvious that whichever Bluetooth module that could be chosen, a Bluetooth profile, HID, was needed and had to be modified in order to use the conventional “Bluetooth dongles”. This would make a great cost or effort in development time than the scope of the thesis work allowed. From this, a decision was made to also include development of an additional unit to connect to the computer side, which then would replace the “dongle”.The thesis resulted in a prototype consisting of two subsystems, however in need of further development, offering partly the intended functionality. The USB I/O could be started up on a computer wirelessly using the system.

This term is used on several of todays short range wireless technologies like Bluetooth, ZigBee, Infrared etc. In this thesis we look in to how Bluetooth as a PAN technology may be used to enrich context information to a person. Context is information that can be used to characterize the situation of an entity. It may be acquired in many ways, e.g. from user input (status in an IM client), sensed (temperature, location, heart rate), or derived (e.g. combination of location and time of day). Several scenarios showing the benefits of context aware computing will be presented, and proposals on how Bluetooth may fit in as an enabling technology will be evaluated. In the end, a design and implementation showing Bluetooth in context acquisition will be presented.</p>

Full textAbstract:
Bluetooth is a low cost and low power wireless technology for connecting portable and / or fixed Bluetooth enabled devices to form short-range wireless ad hoc personal area networks (PANs). As the Bluetooth specification does not specify a protocol to form ad hoc Bluetooth networks, a method for forming an efficient Bluetooth network under a practical networking scenario is still an open research problem. This thesis introduces an approach to implement an indoor ad hoc Bluetooth wireless network, Bluetooth information exchange network (BIEN). This network formation is based on Bluetooth and Java technologies. A set of Bluetooth enabled devices configured with the BIEN software application are able to spontaneously establish a dynamic multi-hop wireless network using Bluetooth technology without the need of formal network infrastructure, centralized administration, fixed routers or access points. In this study, the performance evaluation focuses on the relation between network capacity and topology by testing end-to-end performance in terms of throughput and the latency of communication links with various parameters, including the hop number between nodes and the number of slaves in piconets. The evaluation results show that the throughput reduces with the increased length of a path, and with an increase in the number of slaves in a piconet in the network. The latency also increases with path length, and with the number of slaves in a piconet in the different experimental BIENs, whether if there is traffic or not in the networks. Experimental results have further confirmed the necessity to minimize the number of bridge nodes in the Bluetooth networks due to their traffic bottleneck effect. This work is an attempt at implementation of a distributed multi-hop scatter net with an integrated routing protocol in the practical environments, while most of the literature focuses on covering the modelling of it. It intends to demonstrate how Bluetooth technology with Java technology can be used to design, develop and deploy ad hoc wireless networks with the commercial Bluetooth devices, and examine how well Bluetooth technology supports ad hoc multi-hop wireless network technology.

Full textAbstract:
The emergence of Bluetooth as a wireless network solution assists in bringing together multiple technologies in different sectors and provides rapid interconnections to form a network paradigm. Typically, up to 8 Bluetooth devices can form a centralized network, called a piconet, controlled by a master node, which allocates transmission slots to all other nodes (slaves) in the piconet. However, the structure of inter-piconet connection: called the scatternet is not defined in the Bluetooth Specification. To develop a new scatternet structure, many challenges such as topology formation, intra and inter-piconet scheduling and packet routing are considered. The thesis addresses these critical issues based on the scatternet formation using Bluetooth. The scatternet, presented in this thesis, employs a tree hierarchy structure formation with a Leader root of three hierarchies. Within the scatternet, the new concept exploits clock and frequency synchronization for all new piconets creation. This synchronization prevents interferences and the need for guard time while switching piconet. Thus enabling a device to switch from one piconet to another at every slot. Furthermore, an innovative intra-piconet design is proposed to improve QoS within Bluetooth piconet. By exploiting the device queue status, the scheme defines a predictable polled sequence, and an adaptive traffic allocation. This offers a better fairness, and a significant power reduction when compared to the conventional Round Robin scheme. Moreover, with the perfect scatternet synchronization, the devices switch to other piconets to transmit data and, within one slot time, return to the initial piconet before the next predicted poll time exchange occurs. This considerably improves the traffic data transfer, especially for a significant number of devices present within the area. In addition, a new routing process is developed in this thesis, which facilitates communication within the scatternet. From the scatternet tree hierarchy position, a new addressing node routing is proposed to keep the overhead network low, and guarantees that any packet forwarded reaches its destination. The performance of the new scatternet is evaluated for each scatternet phase, through a Matlab simulation program, and the significant improvement of Bluetooth QoS achieved through the proposed approach is fully demonstrated. This thesis also presents a primary implementation of the scatternet concept using a dedicated Bluetooth hardware system.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2002.<br>Includes bibliographical references (p. 71-73).<br>There is increasing interest in wireless ad hoc networks built from portable devices equipped with short-range wireless network interfaces. This thesis addresses issues related to internetworking such networks to form larger "scatternets." Within the constraints imposed by the emerging standard Bluetooth link layer and MAC protocol, we develop a set of online algorithms to form scatternets and to schedule point-to-point communication links. Our efficient online topology formation algorithm, called TSF (Tree Scatternet Formation), builds scatternets by connecting nodes into a tree structure that simplifies packet routing and scheduling. Unlike earlier works, our design does not restrict the number of nodes in the scatternet, and also allows nodes to arrive and leave at arbitrary times, incrementally building the topology and healing partitions when they occur. We have developed a Bluetooth simulator in ns which includes most aspects of the entire Bluetooth protocol stack. It was used to derive simulation results that show that TSF has low latencies in link establishment, tree formation and partition healing. All of these grow logarithmically with the number of nodes in the scatternet. Furthermore, TSF generates tree topologies where the average path length between any node pair grows logarithmically with the size of the scatternet. Our scheduling algorithm, called TSS (Tree Scatternet Scheduling), takes advantage of the tree structure of the scatternets constructed by TSF. Unlike previous works, TSS coordinates one-hop neighbors effectively to increase the overall performance of the scatternet. In addition, TSS is robust and responsive to network conditions, adapting the inter-piconet link schedule effectively based on varying workload conditions. We demonstrate that TSS has good performance on throughput and latency under various traffic loads.<br>by Godfrey Tan.<br>S.M.

Full textAbstract:
The iOS 7 Core Bluetooth Framework (CB) is finally at a level where it can be used in projects to create valuable iOS applications. Due to its maximum broadcast radius of 30ft it lends itself to nearby communication. This thesis explores the Bluetooth space generally before delving into location-based data transfer using Bluetooth. The CB provided by Apple is powerful, but somewhat cumbersome. It forces the developer to deal with details related to device discovery and connections which can be tangential to the goal of the developer: sending data between devices. I built the Lightweight Bluetooth Framework (LBF) which makes the features of the CB more accessible by abstracting away from the implementation details of CB. LBF supports any number of data types being transferred as well as any number of total pieces of data regardless of data type. The system accomplishes this by assigning specific Characteristics to a particular data type and having pieces of data be uniquely identified with an ID when they are broadcasted. This unique ID is then used to associated the proper object with the received data. This will enable developers to focus on the implementation of their App without getting hung up on the details of the CB. Additionally, benchmark tests are done on the Lightweight Bluetooth Framework to determine what data transfer speed the framework supports. These tests reveal that transfer speed depends on hardware, but independent of hardware are too slow to transfer images, video, or sound.

Full textAbstract:
In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal. The user can find connectable Bluetooth devices, connect to a device and read measured values through a user interface. The prototype demonstrates how a Bluetooth communication with a Netbiter EC350 can be implemented and the project is therefore considered to be a good basis for future development.

Full textAbstract:
From the last few years many location based system have been introduced e.g. facebook, orkut, youtube and my-space etc. These networks are specially developed for personal computers. Some location based systems are also introduced for mobile device e.g. Plazes, MamJam, Slam and Jambo. All these type of networks are using the concept of social location, which provides the platform where people can join or make communities according to their interests. Numbers of users on these networks are increasing day by day due to their popularity. This popularity gives the opportunity for researchers to explore the characteristics of these social networks at large scale. This knowledge will be then used to improve the existing networks or to develop new networks. Already developed systems for mobile devices are using different techniques (e.g. Radio Frequency Identification, GPS, GSM, WAP etc.) to determine the location of any person. In this thesis, I am going to develop a prototype of system that will find the social location of an individual using passive Bluetooth scanning of mobile devices. The main idea behind this prototype is that the data obtained should be flexible to target different social needs and as well as different social location applications. The research will explore some more areas of Bluetooth by extending its dimension in social location system. The expected output from this research will help human being to overcome some of their social problems. Social location obtained from the prototype can be used to fulfill different social needs of human being. Keywords: Social location, Bluetooth, Physical location, GPRS, Mobile applications.

Detta examensarbete har utförts inom programmet högskoleingenjör i datateknik vid Linköpings Universitet. Syftet med arbetet är att undersöka de säkerhetsbrister som finns med att använda enheter som kommunicerar via Bluetooth inom hälsotillämningar samt vilka steg som kan tas för att skydda sig mot dem. För att studera dessa sårbarheter användes en pulsmätare som anslöts via Bluetooth med en Android-telefon. Vi påvisar i den första delen av rapporten de sårbarheter som finns med att använda Bluetooth genom att utföra ett antal tidigare kända attacker som tidigare inte har studerats i detta sammanhang. I den andra delen av rapporten utförs attackerna igen, men den här gången med en metod för att motverka skadan de kan åstadkomma. Resultaten visar några av de sårbarheter inom applikationer för hälsa som man måste ha i åtanke när man utvecklar system som hanterar känslig data via Bluetooth. Det visar att det går att avvärja flera av de studerade attackerna med relativt enkla metoder som inte kräver någon extra hårdvara

Ubertooth er en Bluetooth monitoringsenhet som tar til sikte å gjøre sikkerhetsvurderinger av Bluetooth tilgjengelig for alle. Ubertooth har muligheten til å oppdage og følge trafikken til spesifikke enheter, noe tilsvarende åpen kildekode enheter ikke gjør. Den er fortsatt under utvikling, men gir fortsatt god oversikt over Bluetooth trafikk som sendes i nærheten. I denne oppgava blir et aktivt injeksjon anngrep foreslått, men ikke realisert i kode. Utfordringen med å sende Bluetooth trafikk til rett tid er enda ikke knekt, og ikke tilstede i Ubertooth enda. Koden til Ubertooth er undersøkt, og muligheten til å implementere angrepet er beskrevet. Eksisterende angrep på Bluetooth er undersøkt og eventuelle forbedringer som kan bli gjort med Ubertooth er undersøkt.

Wearable technology is used today for many different applications such as heart rate monitoring and other clinical applications. This thesis aims at developing a Parkinson tremor monitoring application and contributes to optimizing the power consumptionof the system. The monitoring application is developed by implementing software on an embedded hardware prototype to collect accelerometer sensor data to store it in an SD card and to transfer the sensor data via Bluetooth to PC or mobile devices. Since the wearable device has to consume limited energy supplied by the battery, this project also includes reducing the energy consumption of the system by duty cycling the hardware peripherals of the system.

Denna rapport omfattar konstruktionen av ett fristående drivkort med tillhörande mobilapplikation för styrning och konfiguration av ett hydraulsystem. Projektets syfte var att på beställaren Bosch Rexroth ABs begäran undersöka om pump control module (PCM) - en del ur det existerande Spider 3 styrsystemet - kunde användas som en fristående modul. Hårdvara med en Bluetoothmodul skapades och kopplades mot PCM för att möjliggöra kommunikation via Bluetooth. En mobilapplikation utvecklades i Android studio för att tillåta konfiguration från en mobil enhet. Mjukvaran i PCM modifierades för att kommunicera med Bluetooth-hårdvaran över CAN och även för att tillåta analog styrning av pumpen via en strömstyrd ingång. De grundläggande kraven för systemet uppfylldes och en fungerande prototyp kunde uppvisas vid projektets slut. Prototypen visade stor potential men saknade dock viss funktionalitet som vore önskvärd hos en kommersiell produkt.<br>This report encompasses the development of a standalone drive card with an accompanying mobile application for control and configuration of a hydraulic system. The purpose of the project was to - according to an inquiry from the client Bosch Rexroth - investigate whether the pump control module (PCM) from the existing Spider 3 control system could be used as a standalone module. Hardware including a Bluetooth module was assembled and connected to the PCM to allow communication over Bluetooth Low Energy (BLE). A mobile application where developed in Android Studio to allow configuration from a mobile device. The software of the PCM were modified to communicate with the Bluetooth hardware over CAN and also for allowing analog control of the hydraulic pump through a current controlled input.The basic demands for the system were met and a working prototype could be demonstrated at the end of the project. The prototype did show large potential but was lacking some functionality which would be desirable for a commercial product.

This thesis deals with the design of a sporttester, which is a device capable of calculating the cadence of the taken steps and monitoring the impact force of foot on the ground while running. Exposure to long-term strong impacts while running can cause serious fatigue fractures of the hip, calf bone or the foot area. The purpose of the sporttester is to monitor and signal strong impacts to the runner, thus helping to prevent fatigue fractures. The aforementioned features are evaluated based on the change in acceleration measured by the accelerometer. The calculated values of step cadence, running speed and impact force are sent via Bluetooth Low Energy to a compatible mobile application.

Full textAbstract:
The Bluetooth scattnernet formation problem is to find a network on a graph under constraints inspired by the limitations of Bluetooth technology. The problem is presented along with a summary of the current state of research. A method of finding solution is proposed that takes the problem and splits it into three parts where every part is solved using a distributed algorithm. The approach uses methods from network optimisation to first find a maximal independent subset that makes up the masters of the network, then an assignment of slaves to masters using an auction algorithm and finally a minimal spanning tree that connects the clusters around the masters together. It's shown that a solution can't always be found and it is investigated how often the algorithm finds a solution. The method is then compared to a brute force solution to asses how close to the best possible network the algorithm comes. It was found that for smaller graphs the algorithm lands not far from the best solution. Informal arguments are made regarding optimality and complexity of the method and suggestions for further research are made.<br>Bluetooth scatternet formations-problemet är att hitta ett nätverk på en graf givet vissa bivillkor inspirerade av begränsningarna i Bluetoothteknologin. Problemet presenteras tillsammans med en sammanfattning av nuläget i forskningen kring Bluetoothnätverk. En metod för att hitta lösningar till problemet föreslås som tar problemet och delar upp det i tre delar där varje del löses med en distribuerad algoritm. Tillvägagångssättet använder metoder från nätverksoptimering för att först hitta et maximals oberoende delmängd av nätverket som utgör mästarnoderna, sedan görs en tilldelning av slavar till mästare genom en auktionsalgoritm och till sist tas ett minimalt uppspännande träd fram som kopplar ihop alla kluster kring mästarna. Det visar sig att en lösning inte alltid finns och det undersöks hur ofta algoritmen hittar en lösning. Metoden jämförs sedan med en metod som använder Brute Force för att bedöma hur nära den bästa lösningen metoden lyckas komma. Det visas att för små grafer lyckas algoritmen komma nära det bästa nätverket. Informella argument görs gällande optimalitet och komplexitet och förlag för vidare studier ges.

Sensori, attuatori e tecnologie embedded hanno cambiato il nostro modo di lavorare, allenarci e seguire i nostri interessi. Il mondo del commercio non e rimasto a guardare ed ha dovuto adattarsi alla metamorfosi high-tech del settore dei servizi.
Il sistema proposto costituisce un promotore per acquisti ed un raccoglitore intelligente di abitudini sullo shopping e si compone di applicazione mobile, microcontroller e web server.
Caratteristica prima e principale del progetto e sicuramente la pervasivita. All'utente ed utilizzatore dell'app dello shopping center deve essere certamente resa nota la collaborazione al fine di raccogliere dati statistici sulle sue abitudini, tuttavia sono le modalita di tale operazione a dover rimanere velate, in modo da
non appesantire il cliente con tediose operazioni di invio di feedback e valutazioni ed allo stesso tempo permettere una raccolta capillare delle informazioni. Parallelamente alla raccolta di dati funzionali al producer, sono state implementate features per il consumatore, come notifiche promozionali place-triggered e pubblicita mirata. Tra tutte le tecnologie adibite allo scambio di informazioni, si e scelto l'utilizzo del Bluetooth e del piu recente Bluetooth Low Energy (BLE) per permettere ai dispositivi di comunicare tra loro.

Full textAbstract:
<p>This thesis aims to provide a solution for wireless control of, and communication with and among Khepera robots, making use of the Bluetooth wireless technology, to allow wireless control of multiple robots in real time. It is based on the foregoing work of other students who constructed a module for wireless control of Khepera robots over Bluetooth, but they were not able to control more than one physical robot at a time. Khepera robots, as well as many wireless solutions to control those, are closely investigated, and an introduction to Bluetooth is given. An implementation of a Bluetooth protocol stack, which was carried out in the context of this dissertation, and constitutes one of the main parts of this project, is described in detail. The performance of the work discussed throughout this dissertation is evaluated w.r.t. transmission times of data over the wireless link, and afterwards compared to other solutions for real-time control of Khepera robots, e.g. a solution to control a Khepera robot over a wireless radio link. Furthermore, previously simulated experiments with autonomous agents are carried out on physical robots, to test the quality of the wireless solution. It is shown that the solution presented here operates much more efficient than any other existing solution, thus provides a very useful aid for the research community that is experimenting with physical robots in general, and real Khepera robots in particular, in order to simplify research, and allows for a broader spectrum of experiments.</p>

Full textAbstract:
<p>To make services for mobile devices more user friendly wireless communication is a very helpful tool. Wireless communication normally requires no or very little user input, and communication over a wireless interface is therefore in many cases preferred. A trend today is for example that radio or TV shows are recorded to your mobile device during the day. When arriving your home/office the media file can be transferred or streamed to your desktop computer and/or stereo for better sound and larger screen. Normally this is done using a docking station, but this could also be done through a wireless interface. Combining wireless communication with more advanced service logic opens the possibilities for easier file sharing between mobile devices in a peer-to-peer fashion. This thesis evaluates ActorFrame as a framework for service creation in Bluetooth ad hoc networks. Through the thesis limitations in the Bluetooth protocol and mobile devices supporting the Bluetooth protocol are discovered. One of the known limitations of Bluetooth is the range limitation, since Bluetooth only is a short range protocol. To extend the range between Bluetooth enabled devices they must be able to function as mediators. For this to be possible information regarding available services on the different devices must be exchanged. This task is performed by routing protocols. The existing routing protocol in ActorFrame is evaluated, and a study of alternative wired and wireless routing protocols is also done. Besides user friendliness a service should be as cheap as possible. This way as many people as possible will use the service. The Bluetooth functionality integrated in the framework evaluated in this thesis could be utilized in a beneficial way. For example the functionality could be used in peer-to-peer kind of services mentioned above, where a media file is transferred from the mobile device to the desktop computer. Other wireless technologies could also be used for this purpose, namely GPRS or UMTS. As opposed to Bluetooth transmission, which is free, data transmission using either of these two technologies cost money to use. If ActorFrame could be used in a beneficial way depends on the performance of the Bluetooth functionality. Performance below what a certain service demands, where UMTS can offer the required performance quality, would imply that the framework could not be used in a beneficial way. To test this performance the possibilities of streaming MP3s via the Bluetooth interface using ActorFrame based devices is studied, where a prototype is designed. Through this study limitations both regarding mobile devices running applications based on the ActorFrame framework and the framework itself are discovered.</p>

Bluetooth is a wireless technology that is used to communicate over personal area networks (PAN). With the advent of Internet of Things (IOT), Bluetooth is the technology of choice for small and short range communication networks. For instance, most of the modern cars have the capability to connect to mobile devices using Bluetooth. This ubiquitous presence of Bluetooth makes it important that it is secure and its data is protected. Previous work has shown that Bluetooth is vulnerable to attacks like the man in the middle attack, Denial of Service (DoS) attack, etc. Moreover, all Bluetooth devices are mobile devices and thus power utilization is an import performance parameter. The attacker can easily increase power consumption of a mobile device by launching an attack vector against that device.
As a part of this thesis we present an anomaly based intrusion detection system for Bluetooth network, Bluetooth IDS (BIDS). The BIDS uses Ngram based approach to characterize the normal behavior of the Bluetooth protocol. Machine learning algorithms were used to build the normal behavior models for the protocol during the training phase of the system, and thus allowing classification of observed Bluetooth events as normal or abnormal during the operational phase of the system. The experimental results showed that the models that were developed in this thesis had a high accuracy with precision of 99.2% and recall of 99.5%.

The Bluetooth technology is still in an early stage of development. Much more research can and will be done before the performance of Bluetooth reaches its peak. During the recent years, ideas to integrate Bluetooth units in larger networks have arose, with the Bluetooth unit in the role as access point to the network. This behavior opens up for new possibilities but also increases the requirements on performance. In this thesis the main topic is improvement of piconet performance. The piconet, with the Master unit as access point, is studied from a teletraffic engineering point of view. Different performance attributes and behaviors have been found and investigated. With the outcome of these investigations in mind, new and more efficient policies and algorithms are proposed for both data and voice. A policy increasing the utilization of available bandwidth in a piconet is presented. Furthermore, a proposal is presented where multiple Bluetooth units are used in an efficient manner to support voice calls. The proposed solution does also enable creation of simple teletraffic models to be used for dimensioning.<br>Phone: +46709138850

Next, we develop a new simulator, Bluetooth Worm simulator (BTWS), which simulates Bluetooth worm' behaviors in Mobile wireless networks. Through analyzing the result, we find i) In ideal environment the mobility of Bluetooth device can improve the worm's propagation speed, but combining mobility and inquiry time issue would cause a Bluetooth worm to slow down its propagation under certain situation. ii) The number of initially infected Bluetooth devices mostly affects the beginning propagation speed of a worm, and energy issue can be ignored because the new technology can let Bluetooth device keeping work for a long time. iii) Co-channel interference and setting up monitoring system in public place can improve the security of Bluetooth wireless network.<br>M.S.<br>School of Electrical Engineering and Computer Science<br>Engineering and Computer Science<br>Computer Science MS

Full textAbstract:
Restider är alltid intressanta, för de som använder vägen och de som är ansvariga för vägen. Det finns olika tekniker för att samla in information om restider, till exempel traditionella videobaserade system och nyare system som använder Bluetooth. Bluetooth är en kostnadseffektiv metod som använder väganvändarnas olika elektroniska enheter, till exempel smartphones eller trådlösa headsets, för att samla in information om restider. Den infrastruktur som behövs för att mäta restid är två stycken Bluetooth-mottagare varav en placeras i början och en i slutet av vägsträckan samt en server som tar emot och analyserar insamlad data. Bluetooth fungerar bra för att samla in information om restider, men är tekniken möjlig att använda för att identifiera restider för specifika transportslag? I det här projektet undersöks möjligheterna att identifiera restider som hör till cyklister i Bluetooth-data från stadstrafik. För att de restider som samlas in ska vara intressanta måste de rensas på så kallade outliers, det vill säga observationer som inte representerar den faktiska restiden på vägsträckan. Projektet undersöker därför ett antal olika filtreringsalgoritmer för att kunna rensa insamlad data från outliers. Filtreringsalgoritmerna jämförs först med varandra för att se vilken eller vilka som fungerar bäst i olika trafikmiljöer. Därefter jämförs filtreringsalgoritmerna med de interna filtreringsalgoritmerna som leverantören av Bluetooth-mottagarna, BLIP Systems, använder i sitt analysverktyg för att erbjuda en helhetslösning. Projektets slutsatser är att Bluetooth fungerar bra som insamlingsteknik för restidsinformation och att de restider som ges inte är signifikant skilda från restider som samlas in med andra, mer traditionella, insamlingstekniker. Det går dock inte att dra några konkreta slutsatser vad gäller möjligheterna att identifiera cyklister i blandad stadstrafik på den vägsträcka som testas i projektet. Detta på grund av att bilar och cyklister har för lika restid på vägsträckan. Metoden som används bör dock testas på ytterligare vägsträckor innan det är möjligt att fastslå om den fungerar eller inte. Av de olika filtreringsalgoritmerna som testas är det en Box och Whisker-algoritm, som använder IQR-teknik för filtreringen, som presterar bäst på indata från stadstrafik och indata från motorväg. Indata från mellanstora vägar tas inte med i resultatet. När Box och Whisker-algoritmen jämförs med Bluetooth-mottagarnas interna filtreringsalgoritmer är resultatet att Bluetooth-mottagarnas filtreringsalgoritmer ger ett något bättre resultat än Box och Whisker-algoritmen, men att den ändå ger ett fullgott resultat.

The recent proliferation of Bluetooth Devices has caught the attention of hackers. With Bluetooth devices being put in everything from cell phones to PDAs to laptops, the abuse of this technology could have an even bigger impact than the viruses and malware running rampant on the internet. Bluetooth is a short range wireless technology intended to interconnect consumer electronics devices of all kinds. The same features that make Bluetooth so attractive to manufacturers, also makes it attractive to hackers. Bluetooth devices can quickly setup up ad-hoc networks with other, previously unknown devices. Hackers have started to take advantage of the ease with which a connection can be established along with the average user's lack of computer security knowledge to break into PDAs, cell phones to steal address books and credit card numbers.

One of the largest obstacles that must be overcome in Bluetooth security is the mobility of devices and the relatively short duration of connections. In the Internet, threats can often be traced back to a source, and in many cases the source of the threat can be shut down. However, in a Bluetooth Network devices connect directly to one another, and there are no wires to follow to pinpoint the offending device. This thesis will explore the techniques for the location of Bluetooth Devices. An ideal position location system would be one that operates completely within the Bluetooth Specification. Such a system will be able to use any available Bluetooth Device to find the location of other devices. The primary focus of this thesis will be on such a system, with an overview of traditional radio position location techniques and Bluetooth so that we might gain some insight into how these techniques can be applied to Bluetooth. Data are presented from an extensive set of measurements to relate Bluetooth RSSI and distance on CSR BlueCore02 devices. Finally the results of the data are analyzed to give a rough estimate of the range error that would be incurred in the implementation of such a system.

Using a typical office environment, the study examines the probability and effects of Co-Channel interference as Bluetoothâ ¢ ad-hoc networks are formed in adjacent offices. A computer aided simulation tool, MATLAB simulates a low to highly dense interfering Bluetoothâ ¢ environment which provides the parameters to evaluate the bluetooth co-channel interference and performance. Several metrics are identified to predict Bluetoothâ ¢ performance in a piconet after a collision has occurred: data through put, the probability of frequency collision, transmitter - receiver distance, and power received. Next, to predict Bluetooth performance we also need to define what constitutes a lost packet.

Full textAbstract:
Bluetooth is used in modern cars to connect smartphones to stream music, to access internet and for phone services such as phone book contacts and making calls. Similar features are now requested by customers of maximatecc's products, e.g. display computers, for offroad vehicles. This thesis is aimed to investigate what is needed to support these features in maximatecc's Linux based displays and how the features can be used in a Qt application. For instance, the connectivity features in personal cars most commonly utilizes the Bluetooth profiles: Advanced Audio Distribution Profile (A2DP) Audio/Video Remote Control Profile (AVRCP) Personal Area Network (PAN) Profile Hands Free Profile (HFP) Phone Book Access Profile (PBAP) Message Access Profile (MAP). In Linux operating system the Bluetooth stack Bluez is used in the lower level implementation. Open source software components recommended to implement the above profiles includes: Obexd (for MAP and PBAP) PulseAudio (for A2DP and HFP) oFono (for HFP) Connman (for PAN) all of which help to implement the top level profiles of the Bluetooth stack needed, easily controlled by a Qt application through DBus. Most of the external software components were not possible to add to the Linux image on the CCpilot VA display during the period of the thesis. Instead some features of the profiles have been tested, through a Qt demo and python test scripts, on a Virtual Machine in an environment similar to the CCpilot VA. All profiles tested had some functionality verified except for AVRCP, which is not supported until later versions of Bluez, not available for the Linux kernel on the CCpilot VA. However, the audio in the HFP only occasionally worked. On the CCpilot VA only PBAP was tested successfully.

Full textAbstract:
Globally, population numbers are growing, and the lifespan of the elderly is increasing. Therefore, this phenomenon requires that society commit more money, facilities, and staff for health care. The Internet of Things (IoT) can be employed to cover the financial shortfall in healthcare resources by using sensors for remote health monitoring such as the Shimmer device. The Shimmer physiological sensor is a Bluetooth-enabled radio device designed and used for monitoring various human health conditions. Using a sufficient number of the Shimmer devices with proper sampling rate can affect the provision of health and related information in realtime. Moreover, this type of sensor can sometimes be attached to the human body, which can create an inference between the sensors and the human body. The high-noise environment may also impact the sensor. This thesis reviews and analyses several scenarios in which Shimmer devices can be used by medical practitioners to offer reliable physiological measurements, such as ECG and movement. This study found that the Shimmers device can provide reliable data by using a specific configuration when the maximum number of sensors participate in a piconet network.
