Abstract:
Le travail présenté ici s'inscrit dans la perspective du développement de modules électroniques à très faible coût et à très faible consommation pour les réseaux de capteurs sans fils (WSN). Il traite de la conception et du test d'une chaîne de réception RF compatible avec la norme IEEE 802.15.4 pour la bande ISM 2.4GHz. L'interface RF objet de notre étude inclue toutes les fonctions depuis l'antenne jusqu'au 1er étage du filtre analogique en bande de base, à partir duquel le gain devient suffisant pour masquer le bruit introduit par le reste de la chaîne de réception. Ce mémoire articulé autour de quatre chapitres, décrit toutes les étapes depuis la définition des spécifications de la chaîne de réception jusqu'à la présentation de ses performances, en passant par l'étude de son architecture et la conception de ses différents étages. Suite à l'étude de l'impact des interféreurs IEEE 802.15.4 et IEEE 802.11b présents dans la bande ISM 2.4GHz, une architecture utilisant une fréquence intermédiaire de 6MHz a été retenue. En outre, pour pouvoir répondre aux spécifications fixées, cette architecture est composée de plusieurs étages innovants ou originaux tels qu'un balun intégré trois accès, un amplificateur faible bruit sans inductance, un mélangeur passif piloté par un signal local (OL) à très faible rapport cyclique ainsi qu'un filtre bande de base optimisé en bruit et en linéarité. Intégré dans une technologie CMOS 90nm, ce récepteur occupe une surface de 0.07mm², ou 0.23mm² en incluant le balun intégré, qui représente une réduction de 70% par rapport à l'état de l'art des puces compatibles avec le standard IEEE 802.15.4. En prenant en compte la consommation dynamique de toute la chaîne de mise en forme du signal OL, la tête de réception précédemment décrite consomme seulement 4mA sous une tension d'alimentation de 1.35V. Enfin, en incluant le balun intégré, le gain est de 35dBv/dBm, le facteur de bruit de 7.5dB, l'IIP3 de -10dBm et la réjection d'image supérie ure à 32dB. Ces performances placent ce récepteur parmi les récepteurs RF les plus performants pour cette application. Les nombreux principes mis en Suvre sont par ailleurs transposables à d'autres bandes de fréquences et à d'autres standards de communication.

Abstract:
Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra
As Redes de Sensores Sem Fios (RSSF) são atualmente uma tecnologia muito promissora e com inúmeros cenários práticos de aplicação, que vão desde a monitorização do ambiente, controlo de edifícios inteligentes, monitorização de funções fisiológicas vitais, até às aplicações industriais ou militares. Os nós sensores são dispositivos sem fios, autónomos de baixo custo, e dispõem de capacidade limitada de processamento e memória, bem como restrições ao nível da energia de que dispõem para desempenhar as suas tarefas. As redes de sensores encontram-se progressivamente a evoluir para cenários de aplicação nos quais os nós sensores estarão interligados de forma totalmente transparente com a Internet. As aplicações ubíquas farão parte provavelmente do nosso dia-a-dia e os nós sensores possuirão a capacidade para comunicar com outros equipamentos através da Internet, recorrendo a protocolos e aplicações alicerçadas no Protocolo IPv6. Este trabalho pretende abordar a segurança no contexto da comunicação entre nós sensores e sistemas Internet hosts ou outros nós sensores de forma segura, explorando em particular tecnologias de segurança end-to-end assim como outras tecnologias auxiliares necessárias à proteção das redes de sensores no contexto da sua integração com a Internet O trabalho desenvolvido pretende avaliar os mecanismos de segurança para CoAP baseados em DTLS, assim como propor uma nova arquitetura de segurança para aplicações sensoriais utilizando CoAP, avaliando e comparando as duas aproximações à segurança endto- end e explorando as suas vantagens e limitações.
