This thesis deals with different approaches to filtering the signal output of a three axis accelerometerfor free space orientation, that is, finding the orientation of a sensor relative to gravity. Theplatform this orientation system is to be developed for is a low-power, high-efficiency fixed-pointmath microprocessor, therefore efficiency and mathematical operation precision are factors thatalso need to be taken into consideration in this work.This is an exploratory work which goals are to analize potential filtering solutions for free spaceorientation with a three-axis accelerometer, develop a tool to validate the theorical analysis, studythe repercusions of limited precision math on those algorithms and implement a filtering solutionas versatile as possible.The goal of finding the orientation with the output of an accelerometer and without a prioriinformation is deceptively simple: while in relaxed state and within inertial systems the outputof a three axis accelerometer and the direction of gravity is the same, when that hypothesis istaken away measurements output by the accelerometer include both gravity and acceleration dueto external forces applied to the system.The contributions of this thesis are a discussion of potential solutions for free space orientationwith unrestrictive preconditions by use of an accelerometer, and an implementation of such solutionfor the MSP430, popular platform of choice for digital signal processing. The main purposeof such a solution is to improve the precision with which gravity is estimated from the outputof the accelerometer. Potential applications of this work are relative position tracking, mapping,positioning systems (for example, within buildings or vehicles, where any other existing positioningsystem cannot work, such as tunnels for GPS).Instead of just low-pass filtering the output of the accelerometer, estimations to the state ofexternal forces applied to the system and tracking of changes to those forces are presented. Tomodel that system, the Kalman filter and the Particle filter are introduced and analyzed as potentialsolutions.This document includes a discussion of both Kalman and Particle filters, implementation ofa tool to compare and validate the models to estimate gravity, a discussion of the effect of fixedpoint math to those models and an implementation of a gravity estimation algorithm that is typeand plattform agnosic based on the output of a 3-axis accelerometer.All relevant code has been included as an appendix to this work This thesis deals with di_erent approaches to _ltering the signal output of a three axis accelerometer for free space orientation, that is, _nding the orientation of a sensor relative to gravity.

Este documento presenta y discute diferentes soluciones para filtrar la señal de salida de un acelerómetro triaxial con el objetivo de conocer su orientación en el espacio libre, es decir, estimar la orientacifion del senson en relación con la gravedad. La plataforma sobre la cual estos algoritmos han de ser desplegados es un microcontrolador de bajo consumo y alta eficiencia, TI MSP430, por ello, la eficiencia y la precisión de las operaciones matemáticas en los diferentes algoritmos son también tratadas en este documento. Éste es un trabajo de exploración cuyos objectivos son el análisis de soluciones para el filtrado de la señal de un acelerómetro triaxial, el desarrollo de una herramienta para la validación del análisis teórico, el estudio de la repercusión sobre los algoritmos de filtrado de la limitada precisión en las operaciones matemáticas, y la implementación de una solución de filtrado para el microcontrolador MSP430 de Texas Instruments. Encontrar la orientación de un sensor con la señal de salida de un acelerómetro es un abjetivo relativamente complejo: mientras el sensor están estacionario, la señal de salida es la orientación, pero cuando fuerzas externas son aplicadas sobre el sensor, estas fuerzas contribuyen como ruido al problema que se presenta. Las contribuciones de este documento son una discusión sobre potenciales soluciones para el filtrado de la señal de un acelerómetro triaxial para la orientación en el espacio libre, y una implementación de una solución para el microcontrolador MSP430, plataforma popular para el proceso digital de señales. La principal misión de esta implementación es la mejora de la precisión con la que se estima la dirección de la gravedad mediante el uso de un acelerómetro triaxial. Aplicaciones potenciales están relacionadas con seguimiento de posición, mapeado, sistemas de posicionamiento (por ejemplo, dentro de vehiculos o edificios donde otros sistemas no funcionarían, como por ejemplo GPS en un túnel). En lugar de un simple filtro paso bajo para eliminar el ruido introducido por fuerzas externas, estimaciones del estado de las fuerzas externas y filtros para el seguimiento de las mismas son presentados en este documento. Para modelar dicho sistema, se introcucen el filtro de Kalman y el filtro de Partículas, y ambos se analizan como soluciones para este problema. Este documento incluye una discusión de ambos tros, la implementacion de una herramienta de validación para los mismos, anfialisis del efecto de la introducción de álgebra de punto fijo sobre los modelos, y una implementacion del sistema para el MSP430 de Texas Instruments. El código relevante de este trabajo se incluye como apéndice a este trabajo.

An ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Principally an ECG simulator provides ECG monitors with an electrical signal that emulates the human heart's electrical signal so that the monitor can be tested for reliability and important diagnostic capabilities. However, the current portable commercially available ECG simulators are lacking in their ability to fully test ECG monitors. Specifically, the portable simulators presently on the market do not produce authentic ECG signals but rather they endeavor to create the ECG signals mathematically. They even attempt to mathematically create arrhythmias (irregular heartbeats of which there are many different types). Arrhythmia detection is an important capability for any modern ECG monitor because arrhythmias are often the critical link to the diagnosis of heart conditions or cardiovascular disease. The focus of this thesis is the design and implementation of a portable ECG simulator. The important innovation of this prototype simulator is that it will not create its ECG signals mathematically, but rather it will store ECG data files on a memory module and use this data to produce an authentic ECG signal. The data files will consist of different types of ECG signals including different types of arrhythmias. The data files are obtained via the internet and require formatting and storing onto a memory chip. These files are then processed by a digital to analog converter and output on a four lead network to produce an authentic ECG signal. The system is built around the ultra-low power Texas Instruments MSP430 microcontroller.

Resumo: Redes de sensores sem fio têm se tornado populares recentemente e possuem inúmeras aplicações. Contudo, elas apresentam o desafio de como proteger suas comunicações utilizando esquemas criptográficos, visto que são compostas por dispositivos de capacidade extremamente limitada. Neste trabalho é descrita uma implementação eficiente em software, para redes de sensores sem fio, de duas tecnologias de criptografia pública: a Criptografia Baseada em Emparelhamentos (CBE) e a Criptografia de Curvas Elípticas (CCE). Nossa implementação foca a família de microcontroladores MSP430 de 16 bits, utilizada em sensores como o Tmote Sky e TelosB. Em particular, para a CBE, foram implementados algoritmos para o cálculo de emparelhamentos nas curvas MNT e BN sobre corpos primos; para a CCE, foi implementado o esquema de assinatura ECDSA sobre corpos primos para os níveis de segurança de 80 e 128 bits. As principais contribuições deste trabalho são um estudo aprofundado dos algoritmos de emparelhamentos bilineares e novas otimizações na aritmética de corpos primos para a MSP430, que consequentemente melhoram o desempenho dos criptossistemas de CBE e CCE em tal plataforma
Abstract: Wireless sensor networks have become popular recently and provide many applications. However, the deployment of cryptography in sensor networks is a challenging task, given their limited computational power and resource-constrained nature. This work presents an efficient software implementation, for wireless sensor networks, of two public-key systems: Pairing-Based Cryptography (PBC) and Elliptic Curve Cryptography (ECC). Our implementation targets the MSP430 microcontroller, which is used in some sensors including the Tmote Sky and TelosB. For the PBC, we have implemented algorithms for pairing computation on MNT and BN curves over prime fields; for the ECC, the signature scheme ECDSA over prime fields for the 80-bit and 128-bit security levels. The main contributions of this work are an in-depth study of bilinear pairings algorithms and new optimizations for the prime field arithmetic in the MSP430, which improves the running times of the PBC and ECC cryptosystems on the platform

Most major cell phone manufacturers have been releasing cell phones equipped with Near Field Communication (NFC). At the same time there is also increasing use of mobile payments and user verification with the use of the NFC technology. These trends indicate both the increasing popularity and great potential for increased use of NFC in today’s society. As a result NFC has a huge potential to simplify our everyday tasks, ranging from paying for items to accessing our office or home. In this context we will focus on using NFC together with a Power over Ethernet (PoE) powered circuit board and NFC reader to realize a simple system for granting access to open a locked door. One of the purposes of this realization is to explore what services can be realized when such a system is connected to the home/building network and connected to the Internet. A second purpose is to learn how to use network attached devices, as the concept of the Internet of Things is considered by many to be a driving force in the next generation Internet. This project uses very in expensive and low power hardware, as the number of devices is potentially very large and thus in order to minimize the technology’s impact on the environment we must consider how to minimize the power used – while maintaining the desired user functionality. This bachelor’s thesis project made it possible for a PoE powered circuit board containing a MSP430 microcontroller to work along with a NFC reader, which was connected through the Serial Peripheral Interface (SPI). We hope that the end result of this project will lead to a simpler life by exploiting this increasingly ubiquitous technology. For example, a homeowner could send a one-time key to a repair person who is coming to fix their sink. Similarly a homeowner could send a key to their neighbor which is valid for two weeks so that their neighbor could come into their home to water the plants while they are away on vacation. Another example is lending your apartment key to a friend while you are out of town.
Det blir allt vanligare med närfältskommunikation (NFC) i dagens samhälle, mobiltelefons-tillverkarna börjar utveckla nya telefoner med NFC teknik inbyggd, samtidigt som användningen av NFC ökat. Det sker även en utveckling inom mobila betalningar och användar-verifiering med användning av NFC, då NFC förenklar detta. Med detta sagt kommer vi att arbeta med detta i detta kandidatexamens-arbete där vi fokuserar på NFC samt Power over Ethernet som använder MSP430 chippet som kärna. Med dessa enheter kombinerade kommer en enkel rörelse med ett NFC kort över en NFC läsare som sedan skall ge åtkomst till en låst dörr. Detta i större kombination med en Internetuppkoppling kunna ge ägaren möjligheten att kunna skicka ut dörrnycklar till andra användare. I detta kandidatexamensarbete gjorde vi det möjligt för ett PoE kretskort bestående av ett MPS430 mikroprocessor att samarbeta med en NFC läsare genom SPI protokollet. Genom att utveckla detta projekt hoppas vi att vårt slutresultat leder till en enklare delning av nycklar med hjälp av denna teknologi.

Increasing the complexity of modern electronic systems leads to Electronic System Level (ESL) modeling concept, which supports hardware and software co-design and co-verification environment in a single framework. SystemC language, which is an IEEE approved electronic design standard for system design and verification processes, provides such an environment by supporting a wide range of abstraction levels from system-level to register-transfer level (RTL). In this thesis, two different models of a processor core, whose instruction set architecture (ISA) is compatible with 16-bit TI MSP430 microcontroller, are designed by employing the classical hardware modeling capability of the SystemC language. With its well-designed orthogonal instruction set, elegant addressing modes, useful constant generators and flexible von-Neumann architecture, 16-bit RISC-like processor of the MSP430 microcontroller is an ideal selection for the system-on-a-chip (SoC) designs. Instruction set and addressing modes of the designed processors are simulated thoroughly. In addition, original 16-bit and 32-bit cyclic redundancy code (CRC) programs are used in order to verify the processor cores. In this study, SystemC to hardware flow is also illustrated by synthesizing the Arithmetic and Logic Unit (ALU) part of the processor into a Xilinx-based hardware.

Embedded systems are so ubiquitous that they account for almost 90% of all the computing devices. They range from very small scale devices with an 8-bit microcontroller and few kilobytes of RAM to large-scale devices featuring PC-like performance with full-blown 32-bit or 64-bit processors, special-purpose acceleration hardware and several gigabytes of RAM. Each of these classes of embedded systems have unique set of challenges in terms of hardware utilization, performance and power consumption. As network connectivity becomes a standard feature in these devices, security becomes an important concern. Public Key Cryptography is an indispensable tool to implement various security features necessary on these embedded platforms. In this thesis, we provide optimized PKC solutions on platforms belonging to two extreme classes of the embedded system spectrum. First, we target high-end embedded platforms Qualcomm Snapdragon and Intel Atom. Each of these platforms features a dual-core processor, a GPU and a gigabyte of RAM. We use the SIMD coprocessor built into these processors to accelerate the modular arithmetic which accounts for the majority of execution time in Elliptic Curve Cryptography. We exploit the structure of NIST primes to perform the reduction step as we perform the multiplication. Our implementation runs over two times faster than OpenSSL implementations on the respective platforms. The second platform we targeted is an energy-harvested wireless sensor node which has a 16-bit MSP430 microcontroller and a low power RF interface. The system derives its power from a solar panel and is constrained in terms of available energy and computational power. We analyze the computation and communication energy requirements for different signature schemes, each with a different trade-off between computation and communication. We investigate the Elliptic Curve Digital Signature Algorithm (ECDSA), the Lamport-Diffie one-time hash-based signature scheme (LD-OTS) and the Winternitz one-time hash-based signature scheme (W-OTS). We demonstrate that there’s a trade-off between energy needs, security level and algorithm selection. However, when we consider the energy needs for the overall system, we show that all schemes are within one order of magnitude from each another.

Commercial off-the-shelf (COTS) microcontrollers can be useful for non-critical processing on spaceborne platforms. Many of these microprocessors are inexpensive and consume little power. However, the software running on these processors is vulnerable to radiation upsets, which can cause unpredictable program execution or corrupt data. Space missions cannot allow these errors to interrupt functionality or destroy gathered data. As a result, several techniques have been developed to reduce the effect of these upsets. Some proposed techniques involve altering the processor hardware, which is impossible for a COTS device. Alternately, the software running on the microcontroller can be modified to detect or correct data corruption. There have been several proposed approaches for software mitigation. Some take advantage of advanced architectural features, others modify software by hand, and still others focus their techniques on specific microarchitectures. However, these approaches do not consider the limited resources of microcontrollers and are difficult to use across multiple platforms. This thesis explores fully automated software-based mitigation to improve the reliability of microcontrollers and microcontroller software in a high radiation environment. Several difficulties associated with automating software protection in the compilation step are also discussed. Previous mitigation techniques are examined, resulting in the creation of COAST (COmpiler-Assisted Software fault Tolerance), a tool that automatically applies software protection techniques to user code. Hardened code has been verified by a fault injection campaign; the mean work to failure increased, on average, by 21.6x. When tested in a neutron beam, the neutron cross sections of programs decreased by an average of 23x, and the average mean work to failure increased by 5.7x.

Mobile platforms for archaeological purposes have increased in use over the last 20 years with many of the developments coming from Continental Europe. Mobile platform developments have mainly focused on one type of instrumentation, offering multiple sensors, depths of detection or frequencies. This development of mobile platforms has focused on data acquisition rates but has not considered the physical impact on the soil. The Geoscan Research Mobile Sensor Platform (MSP40) was intended to improve survey efficiency and remain a lightweight system. The platform can collect two earth resistance configurations that show directional variation of the current flow through soil. Additional sensors were integrated on to the square frame of the hand-pulled cart to record simultaneous fluxgate gradiometer data and a microtopographic surveys. Ground based geophysical investigation will always have a physical impact on a site. The MSP40 is no exception but careful selection of wheel types and the lightweight frame limit the damage compared to many mobile arrays.

Mobile platforms for archaeological purposes have increased in use over the last 20 years with many of the developments coming from Continental Europe. Mobile platform developments have mainly focused on one type of instrumentation, offering multiple sensors, depths of detection or frequencies. This development of mobile platforms has focused on data acquisition rates but has not considered the physical impact on the soil. The Geoscan Research Mobile Sensor Platform (MSP40) was intended to improve survey efficiency and remain a lightweight system. The platform can collect two earth resistance configurations that show directional variation of the current flow through soil. Additional sensors were integrated on to the square frame of the hand-pulled cart to record simultaneous fluxgate gradiometer data and a microtopographic surveys. Ground based geophysical investigation will always have a physical impact on a site. The MSP40 is no exception but careful selection of wheel types and the lightweight frame limit the damage compared to many mobile arrays. The MSP40 has been tested on a number of different soils at various times of the year with encouraging results; however issues with overcoming the contact resistance of electrodes remain. The continuous collection rate and combination of techniques means a slight drop in data quality is inevitable. However the increased data density, multiple-sensors and improved rate of collection offset reductions in data quality. The research has shown that the MSP40 can perform low impact rapid site assessments on 'vulnerable' sites, whilst maximising the information gained from a single traverse.

MSP3-1, candidat vaccin antipaludique, a fait l’objet d’un essai clinique sous forme d’un peptide synthétique comprenant une séquence de 69aa cible d’anticorps protecteurs. MSP3-1 appartient à une famille de protéines, partageant des épitopes cibles d’anticorps inhibiteurs du parasite. Il est probablement possible de tirer profit de cette famille d’antigènes homologues, pour induire des anticorps protecteurs chez des individus de fonds génétiques divers. L’objectif de l’étude est de définir des constructions vaccinales améliorées. Pour cela, nous avons évalué, chez les souris C57BL/6J et BALB/c, l’immunogénicité de 4 constructions de MSP3-1, ainsi que celle des autres protéines de la famille MSP3 et d’une construction multigénique basée sur ces mêmes protéines. Parallèlement, l’antigénicité humaine de ces protéines a été étudiée. Les résultats montrent que certaines régions de MSP3-1, modulent la réponse immunitaire contre les épitopes d’intérêt. La construction menée en clinique est rétro-validée, car elle induit des taux d’anticorps élevés, mais l’importance d’une deuxième construction, dépourvue des séquences adjacentes au domaine d’intérêt, comprenant un épitope Th1 favorisant des réponses anticorps cytophiles est démontrée. De même, la construction multigénique induit des anticorps inhibiteurs du parasite, et qui reconnaissent les protéines natives. Parallèlement, les études d’antigénicité humaine ont permis de démontrer une corrélation entre la protection et les réponses anticorps spécifiques des différentes protéines de la famille et de caractériser des séquences cibles d’anticorps inhibiteurs. Ces données permettraient d’améliorer les constructions vaccinales en perspective

One of the challenges of utilizing higher frequencies in the RF spectrum, for any number of applications, is the hardware constraints of analog-to-digital converters (ADCs). Since mid-20th century, we have accepted the Nyquist-Shannon Sampling Theorem in that we need to sample a signal at twice the max frequency component in order to reconstruct it. Compressive Sampling (CS) offers a possible solution of sampling sub-Nyquist and reconstructing using convex programming techniques. There has been significant advancements in CS research and development (more notably since 2004), but still nothing to the advantage of everyday use. Not for lack of theoretical use and mathematical proof, but because of no implementation work. There has been little work on hardware in finding the realistic constraints of a working CS system used for digital signal process (DSP). Any parameters used in a system is usually assumed based on stochastic models, but not optimized towards a specific application. This thesis aims to address a minimal viable platform to implement compressive sensing if applied to a wireless sensor network (WSN), as well as address certain parameters of CS theory to be modified depending on the application.

Le paludisme est la maladie parasitaire la plus mortelle pour les populations humaines. L'agent étiologique de l'infection, Plasmodium spp, est inoculé par des anophèles hématophages. Le candidat-vaccin MSP3, constitué d'une portion du domaine C-terminal de la protéine montra récemment qu'il était capable d'induire la protection contre la maladie chez des enfants africains. Récemment l'intérêt vaccinal de la MSP3 fut soulignée par la définition d'une famille multigénique de protéines partageant une même organisation structurale et ciblées par des anticorps cross réagissant avec l'ensemble des membres de la famille, offrant de nouvelles perspectives pour le développement de vaccins multiantigéniques. Dans cette optique, huit poly protéines (PP) de taille et de composition différentes combinant les antigènes des communs entre les membres de la famille furent synthétisées dans Escherichia coll. Les études d'immunogénicité vis-à-vis de la famille MSP3 dans trois souches de souris génétiquement distinctes (C57BL/6 ; BALB/c ; Swiss), montrèrent qu'elles induisaient assez précocement une réponse anticorps de haute amplitude et homogène indépendamment du fond génétique murin ou de l'immunogène. Cette réponse était constituée principalement de sous-classes d'IgG cytophiles murines (IgG2a, IgG2b, IgG2c). Une observation concordant avec celle obtenue en antigénicité, qui montrait que les anticorps naturellement présents et spécifiques. Des PP dans les sérums issus d'individus en zone d'endémie étaient principalement de nature cytophiles (IgGl, IgG3). Par ailleurs, l'analyse de la réactivité des anticorps induits révéla qu'ils étaient capables de reconnaitre les protéines natives du stade sanguin du parasite, et d'exercer en coopération avec des monocytes humains, une activité antiparasitaire in vitro en ADCL Si ces PP dérivées de MSP3 constituent une version améliorée du premier multigène générée à la suite de la découverte de la famille, la réactogénicité hautement similaire de chacune d'elles est un handicap à surmonter à travers d'autres outils de criblage afin de sélection 2 ou 3 à conduire en expérimentation de phase I chez l'Homme
MSP3 has been shown to induce protection against malaria in African children. The characterization of a family of Plasmodium falciparum merozoite surface protein 3 (MSP3) antigens sharing a similar structural organization, simultaneously expressed on the merozoite surface and targeted by a cross-reactive network of protective antibodies offers new perspectives for the development of subunit vaccines against malaria. Eight recombinant polyproteins containing carefully selected regions of this family covalently linked in different combinations were ail efficiently produced in Escherichia coll. The polyproteins consisted of one monovalent, one bivalent, one trivalent, two tetravalents, one hexavalent construct, and two tetravalents incorporating coiled-coil repeats regions from LSA3 and p27 vaccine candidates. All eight polyproteins induced a strong and homogeneous antibody response in mice of three distinct genotypes, with a dominance of cytophilic IgG subclasses, lasting up to six months after the last immunization. Vaccine-induced antibodies exerted a strong monocyte-mediated in vitro inhibition of P. Falciparum growth. Naturally acquired antibodies from individuals living in an endemic area of Senegal recognized the polyproteins with a reactivity mainly constituted of cytophilic IgG subclasses. Combination of genetically conserved and antigenically related MSP3 proteins provides promising subunit vaccine constructs, with improved features as compared to the first generation construct employed in clinical trials (MSP3-LSP). These multivalent MSP3 vaccine constructs expand the epitope display of MSP3 family proteins, and lead to the efficient induction of a wider range of antibody subclasses, even in genetically different mice. These findings are promising for future immunization of genetically diverse human populations

Lowered voltage has become an important method to enhance the energy efficiency of CMOS circuits. Incorporates in-situ error detection and correction mechanism to recover from timing errors (including the need for error correction cycle Razor and TDTB technique and does not require correction cycle TBLB technique), but also scale down the range of voltage, to save more power consumption. Traditionally, however, the above design is generally based on worst operating conditions to design, while using too much high speed but large power consumption element cells, even lowering supply voltage to recycling energy is still limited; therefore energy efficiency of the use of perspective, still leaves considerable for improvement. This issue needs for Internet of things such as high energy efficiency using an application core design - microcontroller core, it is especially important. This thesis, designed openMSP430 under great process variability of 28nm CMOS technology, for example, proposed to improve the above problems. Significant design technique includes: (1) Using the typical operating condition to design, our purpose is to save circuit area and want to further reduce the active and standby power consumption (2) Using in-situ timing error detection and correction design techniques to solve problems facing the the working conditions deteriorate and the circuit does not work. (3) Useing does not require error correction cycle TBLB technique to match the level of the pipeline depth is only 3 MSP430 (Note: Need error correction cycle Razor and TDTB technique does not apply to just a level of 3 MSP430), while avoiding the architecture of design updates the cost and maintain the continuity of instruction execution. (4) Proposed pre-boost technique to solve the limitation of the last Memory stage of the pipeline cannot be used TBLB technique. (5) Through systematic instruction analysis, "conditional pre-boost circuit" is designed to reduce TBLB technique voltage boost control circuit complexity and shorten the voltage rise time. (6) Unlike traditional voltage dip technique it is only feasible in the simulation stage, the design since the pre-boost technique, making the run-time automatic voltage dip pursue work has become feasible. (7) Proposes a complete design flow in order to properly compare "worst case" and "typical case" overall performance of the two designs, in order to be able to propose the design method of this study be extended to other types of designs. The actual design and simulation data shows, as opposed to worst case design, this new design in addition to 4% area savings, under normal operating conditions in the solution save power consumption by 35%, and 9% in the worst operating conditions require extra power consumption (relatively a higher voltage) to continue its normal operations..

The purpose of this thesis is to obtain high accuracy tidal data through low-cost, high-mobility, and the high-precision laser rangefinder. Nowadays, the national maritime engineering is rapidly developing, and costs of original equipment are approximately NT$100,000 for the acquisition of tidal data. Setting up tidal gathering stations to acquire a large amount of construction need a larger amount of maintenance funds, and therefore it is resulting in an incomplete data acquisition. This article uses MSP430 as the core processor with its low energy consumption characteristics and stable computing power, to support easy programming and compatible connection with many peripheral devices of I2C, SPI, Bluetooth, and RS-232 etc. This implementation utilizes such feature to integrate the wireless Bluetooth system linked to the control computer in order to prevent the risk of joint corrosion that may be caused by installing the instruments on the seashore. In addition, through the RS-232 interface, the high precision laser rangefinder and UHF radio equipment are welded on the motherboard to achieve a low cost and high accuracy objective. After setup the system, the precision performance was a 1% error less than the pressure type tide where the measuring station is located at Kaohsiung Port Authority Pier 10. As a result, all vessels within a radius of 2.2 km are able to receive the real-time tidal data via radio broadcast and get the water depth correction immediately. Therefore, for all the arrival and departure vessels can get the tide date immediately. The tide data can be transferred to the working boats and to correct water depth also. Such implementation will guarantee a higher quality of construction.

Uninterruptible power systems for the average family have reached an acceptable price range today, but because most products have cost considerations leading to some trade-offs on functionality, the important function of monitoring has been removed. This monitoring function is convenient as it can be used to assess the power system; the aim is to achieve monitoring functionality at a low cost, so that users can better gain a situation understanding of the product. This thesis uses the MSP430 chip module as the core device of the monitoring system. This device is used in parallel with the load voltage divider resistors, and in series with the load micro resistor sampling for the program operation to give the voltage and current load value. The temperature of the device is obtained by the thermistor, and all three data sets are displayed on the LCD and can be sent via Bluetooth to a computer terminal which allows the user to view to the product's status. In addition to the above three information data sets, another point take to note is that of heat dispersion. Proper cooling is necessary to avoid overheating of the battery, as opposed to the traditional use of passive cooling or a fixed speed cooling fan. Our product uses the temperature of the device in order to adjust the fan speed to achieve the necessary cooling with the goal of an energy saving effect.

Στη διπλωματική αυτή μελετήσαμε και υλοποιήσαμε μηχανισμούς ασφαλείας στο επίπεδο προσπέλασης μέσου (MAC) σε ένα ασύρματο δίκτυο αισθητήρων που βασίζονται στο πρότυπο ΙΕΕΕ 802.15.4. Συγκεκριμένα, ξεκινώντας από την υλοποίηση του επιπέδου MAC που υπάρχει στο TinyOS για την πλατφόρμα TelosB, αλλάξαμε το μηχανησμό backoff του CSMA-CA αλγορίθμου ώστε να γίνει συμβατός με το πρότυπο 802.15.4. Επίσης αναπτύξαμε της κατάλλήλες μεθόδους ώστε να ενσωματώσουμε στην υλοποίηση μηχανισμους ασφαλείας. Για το δεύτερο, αναπτύξαμε τον οδηγό (driver) για το ολοκληρωμένο CC2420 radio και κάναμε τις απαραίτητες πειραματικές μετρήσεις συγκρίνοντας το σύστημα σε τρείς λειτουργίες, δηλαδη χωρίς ασφάλεια, με ασφάλεια υλοποιημένη με λογισμικό (SW security) και με ασφάλεια χρησιμοποιώντας το ολοκληρωμενο CC2420 (HW security). Τέλος, μελετήθηκαν οι κύριοι μηχανισμοί διαχείρισης και διανομης των κλειδιών σε ένα δίκτυο και υλοποιήθηκαν δύο από αυτά τα μοντέλα. Το πρώτο βασίζεται στην πιθανολογική πρό-διανομη των κλειδιών ενώ το δεύτερο χρησιμοποιεί μηχανισμους ασυμμετρης κρυπτογραφίας, συγκεκριμένα ECC (elliptic curve cryptography) για να εγκαταστησει συμμετρικά κλειδιά στους κόμβους του δικτύου.
The thesis dealt with the implementation of the main medium access and security mechanisms in a wireless sensor network based on the IEEE 802.15.4 standard. More specifically, starting from the tinyos2.1 medium access implementation on the TelosB platform, the backoff mechanism was altered, in order to become fully 802.15.4 compliant, while the appropriate mechanisms were also developed in order to introduce the protocol's security features in the stack. For the latter, a driver for the CC2420 chip was developed and energy and performance meassurements were conducted, comparing the system under three modes of operation, namely with no security, with SW encryption/authentication and with HW encryption/authentication. Finally, the main mechanisms of key management and distribution in a deployed wireless sensor network were studied and developed. Specifically, we implemented two key management schemes. The first was a probalistic pre-distribution mechanism and the second an ECC (elliptic curve cryptography) mechanism of public cryptography in order to install symmetric keys on the motes.
