This book was released on 2015-09-25 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les reseaux de capteurs sans fil permettent de repondre aux besoins de nombreuses applications de surveillance. Toutefois, les applications deployees sur ces reseaux ont souvent des besoins varies de qualites de service, et il est difficile pour une seule pile protocolaire de repondre a ces besoins. Dans ce livre, nous presentons donc les architectures a multiples piles protocolaires pour les reseaux de capteurs sans fil. Nous nous interessons aux interactions entre ces piles protocolaires, et nous introduisons les notions d'architectures multi-piles locales (le choix de la pile a utiliser est decide localement par chaque n ud) et globales (le choix de la pile a utiliser depend d'un evenement exterieur au reseau). Nous nous concentrons ensuite sur les problemes de boucles de routage qui peuvent survenir, sur les proprietes des protocoles de routage qui induisent (ou non) ces boucles, et sur la maniere de reduire ces boucles ou leur impact."
Book Synopsis Protocoles de routage sans connaissance de voisinage pour réseaux radio multi-sauts by : Ibrahim Amadou
Download or read book Protocoles de routage sans connaissance de voisinage pour réseaux radio multi-sauts written by Ibrahim Amadou and published by . This book was released on 2020 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'efficacité énergétique constitue l'objectif clef pour la conception des protocoles de communication pour des réseaux de capteurs radio multi-sauts. Beaucoup d'efforts ont été réalisés à différents niveaux de la pile protocolaire à travers des algorithmes d'agrégation spatiale et temporelle des données, des protocoles de routage efficaces en énergie, et des couches d'accès au médium avec des mécanismes d'ordonnancement permettant de mettre la radio en état d'endormissement afin d'économiser l'énergie. Pour autant, ces protocoles utilisent de façon importante des paquets de contrôle et de découverte du voisinage qui sont coûteux en énergie. En outre, cela se fait très souvent sans aucune interaction entre les différentes couches de la pile. Ces travaux de thèse s'intéressent donc particulièrement à la problématique de l'énergie des réseaux de capteurs à travers des protocoles de routage et d'accès au médium. Les contributions de cette thèse se résument de la manière suivante : Nous nous sommes tout d'abord intéressés à la problématique de l'énergie au niveau routage. Dans cette partie, les contributions se subdivisent en deux parties. Dans un premier temps, nous avons proposé une analyse théorique de la consommation d'énergie des protocoles de routage des réseaux radio multi-sauts d'appréhender au mieux les avantages et les inconvénients des uns et des autres en présence des modèles de trafic variables, un diamètre du réseau variable également et un modèle radio qui permet de modéliser les erreurs de réception des paquets. À l'issue de cette première étude, nous sommes parvenus à la conclusion que pour être économe en énergie, un protocole de routage doit avoir des approches similaires à celle des protocoles de routage géographique sans message hello. Puis, dans un second temps, nous introduisons une étude de l'influence des stratégies de relayage dans un voisinage à 1 saut sur les métriques de performance comme le taux de livraison, le nombre de messages dupliqués et la consommation d'énergie. Cette étude est suivie par une première proposition de protocole de routage géographique sans message hello (Pizza-Forwarding (PF)) exploitant des zones de relayage optimisées et sans aucune hypothèse sur les propriétés du canal radio. Dans le but de réduire considérablement la consommation de PF, nous proposons de le combiner avec une adaptation d'un protocole MAC asynchrone efficace en énergie à travers une approche transversale. La combinaison de ces deux approches montre un gain significatif en terme d'économie d'énergie avec des très bon taux de livraison et cela quels que soient les scénarios et la nature de la topologique.

This book was released on 2017-03 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les reseaux de capteurs sans fil apportent de nouvelles perspectives. Une des principales contraintes est l'economie d'energie, la batterie devant tenir toute la duree de vie du capteur. La principale source de consommation d'energie etant le radio transmetteur du capteur, plusieurs solutions au niveau de la sous couche MAC ont ete propose afin d'economiser l'energie au niveau de la radio. Parmi celles les plus dediees aux reseaux de capteurs sans fil, on trouve la sous couche MAC definie par la norme IEEE 802.15.4 de ZigBee. Cependant malgre son efficacite, elle souffre de quelques insuffisances dont plusieurs sujets d'optimisations essayent de les traiter. Dans ce cadre s'integre notre projet de mastere qui presente une optimisation du protocole MAC de l'alliance ZigBee en l'adaptant a notre cahier des charges ainsi son implementation sous le simulateur ns-2.Cette optimisation vise a reduire en plus la consommation d'energie et garantir un certain determinisme pour notre reseau de capteurs sans fil, en s'inspirant de quelques protocoles MAC types existants.

Book Synopsis Contribution aux protocoles de routage dans les réseaux de capteurs sans fil by : Ismail Bennis
Download or read book Contribution aux protocoles de routage dans les réseaux de capteurs sans fil written by Ismail Bennis and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux de capteurs sans fil (RCSFs) ont suscité un grand intérêt scientifique durant cette dernière décennie. Un des grands défis des RCSFs est d'assurer une communication avec la Qualité de Service (QoS) exigée par l'application tout en prenant en considération les contraintes intrinsèques des capteurs. Un autre défi est relatif à la génération des trafics hétérogènes avec des priorités diverses, ce qui impose des contraintes supplémentaires aux différents protocoles de communication. Dans cette thèse, nous nous intéressons aux protocoles de routage dédiés aux RCSFs. Dans un premier temps, nous proposons des améliorations de deux protocoles appartenant à deux catégories différentes de routage. L'objectif est de surmonter les contraintes liées aux caractéristiques des capteurs sans fil et d'assurer de meilleure performance. Dans un deuxième temps, nous proposons une solution pour remédier à la vulnérabilité de la technique des chemins multiples aussi bien dans le cas d'une seule source ou que dans le cas de plusieurs sources. Ainsi, nous avons proposé un protocole de routage à chemins multiples, capable de créer des chemins tout en évitant l'effet du rayon de détection de porteuse. Ce protocole nommé « Carrier Sense Aware Multipath Geographic Routing (CSA-MGR) », satisfait la QoS exigée par les RCSFs. Comme application directe de notre solution, nous avons étudié un scénario d'irrigation par goutte-à-goutte en utilisant les RCSFs. Principalement, nous nous sommes intéressés au cas d'un dysfonctionnement de système, tel que la rupture des tuyaux d'irrigation ou bien le blocage des émetteurs. Ainsi, nous distinguons deux niveaux de priorité pour les informations transmises par le réseau, et en utilisant le protocole CSA-MGR, nous concevons un routage selon la priorité exigée. Notre travail a été validé avec NS2 et TOSSIM ainsi par une implémentation réelle sur des noeuds capteurs TelosB. Les résultats des simulations numériques et des tests expérimentaux montrent l'apport de nos contributions par rapport aux solutions existantes.

Book Synopsis Interconnecting Smart Objects with IP by : Jean-Philippe Vasseur
Download or read book Interconnecting Smart Objects with IP written by Jean-Philippe Vasseur and published by Morgan Kaufmann. This book was released on 2010-07-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interconnecting Smart Objects with IP: The Next Internet explains why the Internet Protocol (IP) has become the protocol of choice for smart object networks. IP has successfully demonstrated the ability to interconnect billions of digital systems on the global Internet and in private IP networks. Once smart objects can be easily interconnected, a whole new class of smart object systems can begin to evolve. The book discusses how IP-based smart object networks are being designed and deployed. The book is organized into three parts. Part 1 demonstrates why the IP architecture is well suited to smart object networks, in contrast to non-IP based sensor network or other proprietary systems that interconnect to IP networks (e.g. the public Internet of private IP networks) via hard-to-manage and expensive multi-protocol translation gateways that scale poorly. Part 2 examines protocols and algorithms, including smart objects and the low power link layers technologies used in these networks. Part 3 describes the following smart object network applications: smart grid, industrial automation, smart cities and urban networks, home automation, building automation, structural health monitoring, and container tracking. Shows in detail how connecting smart objects impacts our lives with practical implementation examples and case studies Provides an in depth understanding of the technological and architectural aspects underlying smart objects technology Offers an in-depth examination of relevant IP protocols to build large scale smart object networks in support of a myriad of new services

Book Synopsis Cognitive Radio, Mobile Communications and Wireless Networks by : Mubashir Husain Rehmani
Download or read book Cognitive Radio, Mobile Communications and Wireless Networks written by Mubashir Husain Rehmani and published by Springer. This book was released on 2018-08-31 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.

Book Synopsis The Emergence of Social Space by : Kristin Ross
Download or read book The Emergence of Social Space written by Kristin Ross and published by Verso Books. This book was released on 2020-05-05 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1870s in France - Rimbaud's moment, and the subject of this book - is a decade virtually ignored in most standard histories in France. Yet it was the moment of two significant spatial events: France's expansion on a global scale, and, in the spring of 1871, the brief existence on the Paris Commune - the construction of the revolutionary urban space. Arguing that space, as a social fact, is always political and strategic, Kristin Ross has written a book that is at once a history and geography of the Commune's anarchist culture - its political language and social relations, its values, strategies, and stances. Central to her analysis of the Commune as a social space and oppositional culture is a close textual reading of Arthur Rimabaud's poetry. His poems - a common thread running through the book - are one set of documents among many in Ross's recreation of the Communard experience. Rimbaud, Paul Lafargue, and the social geographer lise Reclus serve as emblematic figures moving within and on the periphery of the Commune; in their resistance to the logic and economy of the capitalist conception of work, in their challenge to work itself as a term of identity, all three posed a threat to the existing order. Ross looks at these and other emancipatory notions as aspects of Communard life, each with an analogous strategy in Rimbaud's poetry. Applying contemporary theory, to a wealth of little-known archival material, she has written a fresh, persuasive, and original book.
