Book Description
Les réseaux de capteurs sans fil (RCSF) sont devenus un thème porteur aussi bien pour la recherche académique que pour les activités des services de R&D en raison de leur simplicité de déploiement et de leur potentiel applicatif dans des domaines très variés (militaire, environnemental, industriel). Un RCSF est composé d'un ensemble de noeuds devant être opérationnels et autonomes énergétiquement pour de longues périodes. De ce fait ils sont limités en capacité mémoire et de calcul, et contraint à exploiter une faible puissance de transmission, ce qui en limite leur portée et rend leur débit modeste. Le besoin de sécuriser les communications dans un RCSF dépend de la criticité des données échangées pour l'application supportée. La solution doit reposer sur des échanges sûrs, confidentiels et fiables. Pour assurer la sécurisation des échanges, des techniques de cryptographie existent dans la littérature. Conçues à l'origine pour des réseaux informatiques majoritairement câblés, elles se basent généralement sur des algorithmes complexes et gourmands en ressource. Dans le cadre de cette thèse, nous avons proposé, implémenté et évalué une architecture sécurisée et dynamique adaptée aux communications des RCSF. Elle permet de garantir et de maintenir la sécurité des communications durant toute la durée de vie d'un réseau multi-saut. Nous avons utilisé et adapté des algorithmes standards de cryptographie, tels que AES-CTR et la suite d'algorithmes basée sur ECC, qui permettent à notre architecture de résister à la majorité d'attaques. Nous avons quantifié le surcoût en temps de calcul et en occupation mémoire de notre solution. Les résultats d'implémentation de notre proposition sont issus de mesures réelles faites sur une maquette réalisée à partir de cartes TelosB.

Book Description
David O. Loomis Illinois State University The explosive growth of the Internet has caught most industry experts off guard. While data communications was expected to be the "wave of the future," few industry observers foresaw how rapid the change in focus from voice communications towards data would be. Understanding the data communications revolution has become an urgent priority for many in the telecommunications industry. Demand analysis and forecasting are critical tools to understanding these trends for both Internet access and Internet backbone service. Businesses have led residential customers in the demand for data services, but residential demand is currently increasing exponentiall y. Even as business demand for data communications is becoming better understood, residential broadband access demand is still largely unexplored. Cable modems and ADSL appear to be the current residential broadband choices yet demand elasticities and econometric model-based forecasts for these services are not currently available. The responsiveness of customers to price and income changes and customer's perceptions of the tradeoff in product characteristics between cable modems and ADSL is largely unknown. Demand for Internet access is derived from the demand for applications which utilize this access; access is not demanded independent of its usage. Thus it is important to understand Internet applications in order to understand the demand for access.

Book Description
Position estimation of wireless devices has many applications in short-range networks. Ultra-wideband (UWB) signals provide accurate positioning capabilities that can be harnessed in wireless systems to realise these applications. This text provides detailed coverage of UWB positioning systems, offering comprehensive treatment of signal and receiver design for ranging, range estimation techniques, theoretical performance bounds, ranging algorithms and protocols. Beginning with a discussion of the potential applications of wireless positioning, and investigating UWB signals for such applications, later chapters establish a signal processing framework for analysing UWB positioning and ranging systems. The recent IEEE 802.15.4a standard related to UWB is also studied in detail. Each chapter contains examples, problems and Matlab scripts to help readers grasp key concepts. This is an ideal text for graduate students and researchers in electrical and computer engineering, and practitioners in the communications industry, particularly those in wireless communications.
