Abstract: With the growth of the Internet of Things (IoT) and other wireless applications in recent years the need for long-range and low-power communication systems has increased. This issue can be resolved by application of LoRa (Long Range) technology, which offers a long-range, low-power, and dependable communication system. LoRa is a wireless modulation technique derived from Chirp Spread Spectrum (CSS) technology. It encodes information on radio waves using chirp pulses in a way similar to the communication principles used naturally by dolphins and bats. LoRa modulated transmission is robust against disturbances and can be received across large distances. In this paper a study on long-range RF text-based communication utilizing LoRa module is presented

Abstract:
New networking issues are presented by the increasing need for a wide variety of applications, which has spurred the creation of a new internet of things (IoT) paradigm, such as long range (LoRa). The LoRa protocol uses a patented kind of spread spectrum modulation to provide low-power, long-range communication. In this paper, we provide a comprehensive review of LoRa-IoT in terms of IoT applications, LoRa class, security and privacy requirements, and the evolution of LoRa technology. This review analysis and compares long range wide area network (LoRaWAN) to wireless technology (e.g., Bluetooth, LoRa, 5G, Sigfox, long term evolution-M (LTE-M), Wi-Fi, Z-wave, Zigbee) and provides a list of environment simulators (e.g., OMNeT++, MATLAB, ns-3, SimPy) to carry out experiment for LoRa-IoT. Finally, this review does not only review literature recently studied for LoRa-IoT but also discusses challenges and future directions.

Abstract:
Long range communications technology (LoRa) has been widely used in a variety of applications and researched in different domains to exploit its full potential. Its openness makes it ideal for a variety of internet of things (IoT) installations which further allows opportunities for viable solutions in vehicular communications. Hence, a bibliometric analysis was performed to distinguish the application and growth of the technology specifically in vehicular communications. The scoping review processes from Arksey and O’Malley was applied to guide the review process. The selected scholarly works adhered to the PRISMA-Sc framework where 385 articles from two main electronic databases, i.e., Scopus and Science Direct which discussed LoRa in vehicular communications contexts were assessed. This study aims to examine how LoRa’s research has grown from year 2010 to 2021 among the scholars and determine key areas discussed in LoRa’s vehicular communications research. Findings from 70 studies in the final analysis indicated that LoRa has been widely studied based on application, theoretical or protocol and performance. However, it has not been widely explored in vehicular context. Hence, our findings support the global research community in this context.

Abstract:
Abstract Keeping proper soil moisture is essential in growing good quality and efficient fruit yield. To that effect, soil moisture level must be controlled, to maintain proper watering. A smartphone application was developed to operate a smart farm watering system. It monitors the soil’s moisture and launches sprayers to water dried areas. The system’s architecture was built in a distributed client-server computing system, in a small computing grid. The grid was built across long range (LoRa) communication networks with the same ID, but different addresses. In terms of integration, the system was built using autonomous microprocessors, which consist of a server and five client microprocessors. A smartphone was used as the server of a central controller, and four moisture detection modules and a water spraying system module were used as autonomous clients. The server was inter-connected with the clients via a star-type topology network in the polling processes. Each client module autonomously analyzes the measured digital voltage of the moisture sensor plugged into the soil. When the server sends queries regarding the status of the moisture level, the client sends the request signal to the server using the LoRa communication technology. The communication between the server and the clients is based on the LoRa communication technology. The LoRa-to-Bluetooth converter is used to connect the Bluetooth and the LoRa signal. The field test was performed in a watermelon field, with an area of approximately 6600 m2. The water spraying system constructed with LoRa communication technology could successfully manage and control the moisture level in the field test.

Abstract:
RF Energy Harvesting is a technology that harvest RF ambient energy from the wearable devices. One of wearable devices that can act as a source is LoRa end device. LoRa (Long Range Access) is part of Low Power Wide Area Network (LPWAN) which operate in unlicensed frequency (ISM). As a technology of wireless network, end devices of LoRa will be taken in remote area that hardly to access. End device LoRa acts as a transceiver that transmits and receives data from the gateway. As a transceiver, the LoRa end device requires energy availability. In remote area, RF ambient energy from the LoRa end device can be utilized as a source of RF energy that can be harvested and stored This paper discusses how to harvest the RF ambient energy emitted by the LoRa end device using the microstrip antenna as the receiver and the voltage multiplier as both a rectifier and a voltage multiplier. The energy harvested from one end device and stored temporarily in the capacitor is 163pJ with a distance 11 cm from the source. This harvested energy can be stored on battery or capasitor bank to be used in future

Abstract:
According to recent researches, the wireless sensor networks (WSN) which consume low levels of energy become more and more popular nowadays, so the research trend of optimizing energy for WSNs is rapidly increasing. LoRa technology is a modulation technique that provides long-range transfer of information and low power consumes. Besides, LoRaWAN is a network protocol that optimized for battery-powered end devices. The LoRa and LoRaWAN can be considered a suitable candidate for WSNs, which can reduce power consumption and extend the communication range. In this paper, we studied adaptive mechanisms in the transmission parameters of the LoRa network and proposed an energy-optimized solution for the adaptive algorithm. This research not only introduced the reference hardware of a sensor node in WSNs but also conducted experiments on typical LoRa network infrastructure

Abstract:
In the proposed work, we present a secure low-cost speech communication system for long-distance communication. The system utilizes long range (LoRa) technology to transmit speech signals. LoRa technology uses spreadspectrum modulation to enable long-range communication with low power consumption. LoRa modulation allows for data transfer at a slow speed, typically below 22 kbps, which makes it infeasible for transmitting speech. To address this limitation, we suggest a speech coding technique that reduces the overall data rate of speech signals to below 7.5 kbps. This lower rate is more compatible with the LoRa module and ideal for transmitting speech. Moreover, this technique can improve the LoRa transmission range. Additionally, we have developed an encryption-decryption method to ensure the privacy of the messages and prevent unauthorized access by third parties.

Abstract:
Les progrès des technologies de communication à faible consommation d’énergie et à faible cout ont révolutionne les applications de télédétection et de surveillance. L’Internet des objets (IoT) a promis la création d’un écosystème d’appareils connectes à travers un large éventail d’applications, telles que les villes intelligentes. A l’heure actuelle, de nombreuses normes et technologies concurrentes tentent de saisir l’IoT, en particulier dans le domaine des technologies de télédétection et de communication. LoRa (Long Range) est l’une de ces technologies qui gagne en popularité et en attraction dans les réseaux de capteurs sans fil (WSN). La possibilité d’établir des communications longue distance avec des nœuds relativement simples, une infrastructure minimale, des besoins en énergie réduits et l’utilisation de bandes ISM sans licence offre un avantage concurrentiel significatif. Bien que la portée de communication dans LoRa puisse dépasser 15 kilomètres en visibilité directe, le débit binaire maximal pouvant être atteint est limite à quelques kilobits par seconde. De plus, lorsqu’une collision se produit dans LoRa, le débit est encore réduit en raison de pertes de trames et de retransmissions. Les travaux de cette thèse traitent le problème des collisions dans LoRa qui peuvent survenir sous une charge importante et qui dégradent les performances du réseau.Premièrement, nous considérons le contexte des communications en liaison montante dans LoRaWAN. Nous étudions le contexte des signaux LoRa en collision synchronisée, ou chaque appareil terminal doit retransmettre toute sa trame en collision après qu’une collision se produit dans LoRa. Ce comportement diminue le débit global et augmente la consommation d’énergie des terminaux et le délai des trames. Pour cette raison, afin d’atténuer les effets néfastes des collisions, nous avons proposé un algorithme de décodage pour résoudre les signaux LoRa en collision synchronisée, dans un trafic réseau sature et confirme. Nous avons remplacé le modèle de retransmission conventionnel de LoRa en un modèle faisant en sorte que les dispositifs terminaux transmettent des bitmaps au lieu de retransmettre des trames entières pour déterminer les symboles corrects de chaque trame en collision. Notre algorithme a pu améliorer significativement le débit global de la couche LoRaWAN MAC à base de LoRa, et diminuer la consommation d’énergie des émetteurs et le délai des trames.Deuxièmement, nous considérons le contexte des communications en liaison descendante dans LoRaWAN. Nous avons remarqué que la liaison descendante dans LoRa est un goulot d’étranglements. Nous avons donc travaillé sur la sélection de la passerelle par le serveur de réseau et son impact sur le débit, la consommation d’énergie et le délai. Nous avons étudié trois types de déploiement de passerelle et nous avons montre que les performances du système dépendent de ce déploiement. Nous avons montré que l’équilibrage du nombre de terminaux par passerelle (également connu sous le nom de charge) améliore le débit par rapport au choix de la passerelle avec la meilleure qualité de signal. En outre, nous avons montré que la combinaison de la charge et de la qualité du signal n’améliore pas davantage le débit. De plus, nous avons montré que le choix de la passerelle avec la meilleure qualité de signal diminue le délai des trames et la consommation d’énergie des terminaux par rapport au choix de la passerelle avec la charge la plus faible<br>The progress in low-energy, low-cost communication technologies have revolutionized remote sensing and monitoring applications. Internet of Things (IoT) has promised an ecosystem of connected devices across a wide range of applications such as in smart cities.Currently, many competing standards and technologies are attempting to seize the IoT, particularly in the area of remote sensing and communication technologies. LoRa (Long Range) is one of those technologies that is gaining popularity and attraction in the Wireless Sensor Networks (WSN) applications. The ability to make long-distance communications with relatively simple nodes, minimal infrastructure, reduced power requirements, and the use of unlicensed ISM bands provides a significant competitive advantage. Although the communication range in LoRa can exceed 15 kilometers in line of sight, the maximum bit rate that can be achieved is limited to few kilobits per second. Additionally, when a collision occurs in LoRa, the throughput is further reduced due to frame losses and retransmissions. The work of this thesis deals with the problem of collisions in LoRa that may occur under heavy load, and which degrade the performance of the network.First, we consider the context for LoRaWAN uplink communications. We study the context of fully synchronized colliding LoRa signals, where each end-device has to retransmit its entire colliding frame after a collision occurs in LoRa. This behavior decreases the overall throughput, and increases the energy consumption of the end-devices, and the delay of the frames. Therefore, in order to mitigate the damaging effects of collisions, we proposed a decoding algorithm to resolve synchronized colliding LoRa signals, in a saturated and confirmed network traffic. We substituted the conventional retransmission model of LoRa by having end-devices transmitting bitmaps instead of retransmitting whole frames to determine the correct symbols of each colliding frame. Our algorithm was able to significantly improve the overall throughput of the LoRaWAN MAC layer based on LoRa, and to decrease the energy consumption of the transmitters and the delay of the frames.Second, we consider the context for LoRaWAN downlink communications. We noticed that the downlink in LoRa is a bottleneck. Hence, we worked on the gateway selection by the network server and its impact on the throughput, the energy consumption and the delay. We studied three types of gateway deployment and we show that the system performance depends on this deployment. We showed that balancing the number of end-devices per gateway (also known as load) improves the throughput compared to choosing the gateway with the highest signal quality. Moreover, we showed that combining load and signal quality does not further improve the throughput. In addition, we showed that choosing the gateway with the highest signal quality decreases the delay and energy consumption compared to choosing the gateway with the lowest load

The thesis is about the construction of a GPS-tracker that can read NFC (Near Field Communication)-tags and communicate with LoRa (Long Range) and BLE (Bluetooth low energy) and investigate which of the components in the GPS-tracker that consumes most power. The usage area for the GPS-tracker is to make the work on disaster affected sites more efficient and secure by having an operation leader that can organizing the operation with help of the information provided by the GPS-trackers that are placed on the injured people and recuing personnel. The GPS-tracker is built around the sensor development kit Thingy:52 from Nordic Semiconductor. The Firmware (FW) for the Thingy:52 is developed by modifying the provided factory FW by Nordic Semiconductor. The GPS-module and the NFC-reader showed to be the most power consuming parts of the GPS-tracker. An energy optimization proposal for these parts are given in the report.

Användningsområdet för GPS-spårsändaren är att effektivisera räddningsinsatser på skadeplatser där det finns skadade människor exempelvis efter en översvämning eller terroristattack. Effektiviseringen är tänkt ska ske genom att en operationsledare styr räddningsinsatsen med hjälp av informationen som skickas från GPS-spårsändarna som kommer att bäras av skadade personer och räddningspersonalen på skadeplatsen.

Abstract:
The main goal of this thesis is to highlight the various limitations that the LPWAN LoRa and by proxy other similar technologies currently suffers from to give further insight into how these limitations can affect implementations and products using such a network. The thesis will be supported by experiments that test how a LoRa network gets affected by different environmental attributes such as distance, height and surrounding area by measuring the signal strength, signal to noise ratio and any resulting packet loss. The experiments are conducted using a fully deployed LoRa network made up of a gateway and sensor available to the public. To successfully deploy a LoRa network one needs to have concrete information about how to set it up depending on different use cases as battery lifetime and a solid connection has to be kept in mind. We test the various performance aspects of a LoRa network including signal quality and packet loss at different communication ranges. In addition to that we also test different environments and investigate how these can impact the performance. The conclusions made in this thesis are that a LoRa network is limited in its use cases for smaller scale projects with low gateway elevation that still require a large distance. This is due to the obstruction of the signal quickly making it reach unusable levels at roughly 300m in a city and 600m in a forest. Making the line of sight free either by elevation of the hardware or by adapting to the terrain makes the network perform very well making the possibility for packet loss lower which in combination with the low duty cycle of the transmissions is needed as every packet lost is going to be very noticeable.

Abstract:
Dagens smarta enheter bygger nuförtiden allt mer på att ständigt hålla sig uppkopplade till allt inom dess omgivning. Industrier och hem innehåller alltmer små batteridrivna sensorer samt enheter som kommunicerar med varandra, dock är detta en begränsning när det gäller räckvidden av en enhet. Målet med denna uppsatsen är att undersöka användarbarhet av nya funktioner inom Bluetooth, samt belysa fördelar och nackdelar vilket kan uppstå med respektive teknologi när det gäller förlängd räckvidd. Vidare utfördes en jämförelsestudie, med målet att framföra skillnader för hur Bluetooth Mesh skiljer sig gentemot de andra Mesh teknologierna.Resultatet av denna uppsatsen visar att Bluetooth Mesh och Long-range har diverse svagheter och styrkor när det gäller olika användningsområden. Överföring av data med en högre hastighet och ett måttligt avstånd skulle vara tillräckligt för Long-range, medan Bluetooth Mesh anpassar sig mer för en större täckning och lättare dataöverföringar.<br>The smart devices of today are more and more dependent on being constantly connected to everything in its surrounding. Industries and homes contain more and more small battery powered sensors and devices, communicating with each other. However, there is a limitation when it comes to the range coverage of a device. The purpose of this thesis is to investigate the usefulness of the new features mesh networking and extended range for Bluetooth, as well as highlight the pros and cons that may exist with respective extended range technologies. Furthermore, a theoretical comparative study was conducted, with the aim of presenting some of the differences between Bluetooth Mesh and other common Mesh technologies. The results show that both Bluetooth Mesh and Long-range have strengths and weaknesses when it comes to different use cases. Transferring data with a bit higher throughput and a moderate distance would be suitable for a Long-range purpose, while Bluetooth Mesh is more suitable for a larger coverage and lighter data transfer.

Abstract:
Every year, certain animal and insect species flock together to make long-range migrations to reach their feeding or breeding grounds. A number of interesting observations can be made regarding this phenomenon. First, individuals tend to create large flocks, which can include millions of individuals in fishes, for these migrations. Second, migrations typically cover long distances. Third, despite all kinds of disturbances affecting the individuals during these migrations, the flocks can reach the very same breeding or feeding grounds with remarkable accuracy. Biological studies indicated that these animals mainly use the magnetic field of earth (among many other environmental cues) to determine the direction of their travel. It was also claimed that migrating in flocks has been the key factor behind the accuracy of reaching the same grounds at the end of the migration. In this thesis, we take a constructivist approach towards investigating the effects of flocking in long-range travels using a swarm of physical and simulated mobile robots. Specifically, we extend a self-organized flocking behavior that was developed by Turgut et al. (2008) that allows the long-range migration of a robotic swarm in space using the magnetic field of the earth. Using this behavior, we analyze how the accuracy of the robotic swarm reaching a particular &quot<br>breeding ground&quot<br>is affected by four factors<br>namely, (1) averaging through the heading alignment, (2) noise in sensing the homing direction, (3) differences in the characteristics of the individuals, and (4) disturbances caused by the proximal interactions of the robots during flocking. Through systematic experiments with physical and simulated robots, we analyze how these factors affect the accuracy along with the flock size and different sources of noise.

Abstract:
Att detektera ljudnivå ger mycket information i stadsområde såsom bullernivå, antal skottlossningar, antal kollisioner och detekterar plats på en ljudkälla. I detta projekt monteras en ljuddetektor som kommunicera via LoRa Long Range när ljudet överstiger ett tröskelvärde. Ljuddetektorn implementeras som en fristående modul bestående av tre befintliga moduler. Modulerna som används i projektet innefattar: Lopy4 med Expansionskort 3.1, GPS modul och Ljud sensor  Ljudnivån, batterinivå, koordinater, datum och tid överförs via LoRa-nät till en gateway och vidare till The Thing of Network, TTN websidan och samtidigt sparas data lokalt i ett SD minneskort när ljudet överstiger ett tröskelvärde. Tröskelvärdet kan modifieras efter användarens önskningar.<br>Detecting noise levels explains a lot in urban areas such as noise levels, number of shots, and number of collisions. In this project, a sound detector is installed that communicates via LoRa, Long Range when the sound exceeds a threshold value. The sound detector is implemented as a stand-alone module consisting of three existing modules. The modules used in the project include Lopy4 with Expansion Card 3.1, GPS module, and Sound sensor. The sound level, battery level, coordinates, date, and time are transferred via LoRa to a gateway and on to The Thing of Network, TTN website, and at the same time data is saved locally in an SD memory card when the sound exceeds a threshold. The threshold can be modified according to the user's wishes.

Abstract:
Abstract LoRaWAN (Long Range Wide Area Network) is a relatively new wireless protocol, which offers many benefits in an industrial setting when compared to others such as Wi-HART and ISA-100. LoRaWAN (LoRa) has been successfully adopted in certain parts of the world such as Europe and North America, while others have yet to adopt the technology. The long range and low power capabilities of LoRa make it a much more cost effective and scalable technology. This paper will cover the differences between the main types of wireless networks available as well as the different sensor types available that can operate on a LoRa network (UT, temperature, vibration, atmospheric, etc.) and possible use cases. The purpose is to present a new type of wireless technology that has many advantages over its predecessors when used in industrial applications. By utilizing LoRaWAN remote sensing technology, operators can have more easily accessible and affordable data. That data can then be used to see how operational changes impact corrosion rates, improve overall operational efficiency, and provide a better understanding of assets.

Abstract:
Abstract Non-intrusive, ultrasound based, corrosion/erosion monitoring systems are becoming more commonly used and accepted as a method to improve data integrity and increase productivity for Oil &amp; Gas asset inspections – especially with underground, insulated, offshore, and other hard-to-access thickness monitoring locations (TMLs). Example applications where installed sensor technologies have been deployed successfully include crude overhead lines, sour water service, offshore risers for sand monitoring, and midstream buried pipelines. Many additional applications of these systems are anticipated to augment static thickness monitoring, improve the accuracy of thickness data/trending, and reduce pressure-boundary penetration of conventional corrosion probes while allowing both remote and real-time monitoring where desirable. A challenge in deploying such systems in brownfield refinery applications is the ability to achieve sensor connectivity at a low cost to the plant infrastructure, allowing a dispersed amount of sensor points to exist within and among multiple process units. A wireless ultrasonic corrosion monitoring device was developed utilizing a long-range, low power wide area network (LPWAN) based on the LORA standard in a star topology. One mile connectivity was achieved in actual refinery testing. The use of a long range, star network allows multiple process units to be connected to a single gateway while preserving node battery life because nodes are not required to relay messages and only connect to the gateway directly. Cellular backhaul was used at the gateway to push data to a cloud back end for data archiving, display and analysis. This paper will review the development of the technology, key features and tradeoffs, and a review of several case studies on the deployment and use of the technology.

Abstract:
The purpose of this research is to investigate the use of a communication network utilizing Long Range (LoRa) low-power wide-area network protocol for the telemetry of detected target chemicals. The sensor platform under development allows traditional electrochemical techniques to be executed with a low Size, Weight, and Power (low SWaP) system that is deployable using an autonomous or remote-controlled vehicle. Once in the field, the sensors communicate target chemical concentrations to a centralized gateway through LoRa to an Internet of Things (IoT) network. Researchers are currently deploying the prototype network for field testing of each node's sensing, meshing, and communication capabilities throughout all weather climates. Developing a robust and dynamic sensor network to monitor the environment and provide a live data feed to detect chemicals of interest in the environment eliminates the need for direct human interaction. The low power consumption of LoRa allows the network nodes to be deployed for an extended amount of time on a single battery supply.

Full text
Abstract:
The objective of this project was to increase the guided wave power of the magneto-strictive sensor (MsS) technology so that the test range of guided wave achievable on pipelines could be further extended. The target goal of the project was a 20-fold (or 26-dB) increase in the guided-wave signal amplitude. The extension in the test range attainable by the 20-fold increase in the guided-wave signal amplitude depends on the wave attenuation coefficient, and alpha;, of the pipe-line under testing and is equal to 26/(2 and alpha;), where the factor 2 accounts for the round trip. For example, for and alpha; = 2.0 dB/ft, the extension in the test range is 6.5 feet; for and alpha; = 1.0 dB/ft, 13 feet; for and alpha; = 0.5 dB/ft, 26 feet; for and alpha; = 0.25 dB/ft, 52 feet; for and alpha; = 0.1 dB/ft, 130 feet; for and alpha; = 0.05 dB/ft, 260 feet.

Abstract:
This brief distils best data practice recommendations through consideration of key issues involved in the use of technology for surveillance, fact-checking and coordinated control during crisis or emergency response in resource constrained urban contexts. We draw lessons from how data enabled technologies were used in urban COVID-19 response, as well as how standard implementation procedures were affected by the pandemic. Disease control is a long-standing consideration in building smart city architecture, while humanitarian actions are increasingly digitised. However, there are competing city visions being employed in COVID-19 response. This is symptomatic of a broader range of tech-based responses in other humanitarian contexts. These visions range from aspirations for technology driven, centralised and surveillance oriented urban regimes, to ‘frugal innovations’ by firms, consumers and city governments. Data ecosystems are not immune from gendered- and socio-political discrimination, and technology-based interventions can worsen existing inequalities, particularly in emergencies. Technology driven public health (PH) interventions thus raise concerns about 1) what types of technologies are appropriate, 2) whether they produce inclusive outcomes for economically and socially disadvantaged urban residents and 3) the balance between surveillance and control on one hand, and privacy and citizen autonomy on the other.
