Book excerpt: Les réseaux à faible consommation d'énergie tels que les réseaux de capteurs sans fil sont actuellement utilisés dans divers domaines militaires, environnementaux, médicaux, et commerciaux. Cette forte demande a été permise grâce à la disponibilité, surtout ces dernières années, de nouveaux microcontrôleurs qui sont plus petits, moins chers et plus intelligents. Ces nouveaux appareils sont équipés d'interfaces sans fil, avec lesquelles ils peuvent communiquer les uns avec les autres pour former un réseau. Dans cette thèse, nous nous concentrons sur l'étude de l'efficacité énergétique des protocoles de transport fiables pour ces réseaux. Récemment, nombreux travaux de recherche ont été menées afin d'améliorer la fiabilité et le contrôle de congestion dans les réseaux à faible consommation d'énergie. Beaucoup de ces travaux ont considéré la pile protocolaire IP/TCP inadéquate pour ce type de réseaux. Initialement, l'idée a été rejetée à cause de plusieurs éléments, comme la surcharge de son en-tête, son mécanisme de retransmission de bout en bout, son taux élevé d'acquittements, et l'impact de la fragmentation des couches inférieures sur sa consommation d'énergie. Néanmoins, l'utilisation de la pile TCP/IP offre l'avantage d'une connectivité transparente entre le nouveau réseau sans fil et Internet. En effet, l'utilisation de TCP facilite l'utilisation des applications standards (e.g., HTTP, SSH) pour de nouveaux besoins comme la reprogrammation des noeuds ou la mise à jour du firmware sans une intervention humaine sur champ et sans un déploiement d'un proxy très complexe au niveau des routeurs de bord. Dans la première partie de cette thèse, nous étudions la consommation d'énergie du protocole TCP et les manières qui permettent de réduire cette consommation. Nous étudions un des algorithmes TCP proposés afin de réduire le coût de la transmission de bout-à-bout et nous proposons une amélioration de ce dernier réduisant encore davantage plus la consommation d'énergie. Nous étudions ensuite la compression de l'en-tête TCP en prenant le réseau 6LoWPAN comme un exemple d'applications. Nous proposons un nouvel algorithme de compression qui permet aussi de réduire la consommation d'énergie. Dans une deuxième partie, nous proposons un modèle mathématique qui permet d'estimer la consommation d'énergie en fonction de plusieurs paramètres. A l'aide de ce modèle, nous étudions le compromis entre l'envoi de longs et courts segments TCP et leur impact sur la consommation d'énergie. Enfin, nous étudions ensuite l'impact d'un nouveau mécanisme de récupération des fragments sur la performance énergétique du protocole TCP.

Download or read book Energy Efficient Hierarchical Wireless Routing Protocol EEHW Routing Protocol written by Samira Anupama Madapatha and published by . This book was released on 2015 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The areas of WSNs (Wireless Sensor Networks) and Internet of Things (IoT) are considered to be the highly embryonic and most emerging arenas in research in the industrial or technical world now. This has brought about the inevitability of introducing or developing highly reliable, highly efficient, low cost, and low power sensor nodes to the market. Primary emphasis of wireless sensor network routing protocol is now on the coup of power preservation. Most of the modern publications have exposed so many protocols primarily intended to minimize the energy consumption in wireless sensor networks. This thesis work recommends an enhancement to the gradient base hierarchical routing protocol technique introduced by Dr. Mozumdar in 2011. Proposed method introduces active/ idle mode for end devices with time division multiplexing to cut down the energy usage of battery powered sensor nodes. At the same time data aggregation at the access point and also backup route has been introduced to end devices to send data back to the base station when the parent node fails to communicate. It is easy to perceive from simulation results that the enhanced protocol has higher lifetime compared to the original protocol. As a closing section, boosted energy efficient hieratical routing protocol (EEHW protocol) is implemented in Contiki OS.

Download or read book JTP An Energy conscious Transport Protocol for Wireless Ad Hoc Networks written by and published by . This book was released on 2006 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within a recently developed low-power ad hoc network system, we present a transport protocol (JTP) whose goal is to reduce power consumption without trading off delivery requirements of applications. JTP has the following features: it is lightweight whereby end-nodes control in-network actions by encoding delivery requirements in packet headers; JTP enables applications to specify a range of reliability requirements, thus allocating the right energy budget to packets; JTP minimizes feedback control traffic from the destination by varying its frequency based on delivery requirements and stability of the network; JTP minimizes energy consumption by implementing in-network caching and increasing the chances that data retransmission requests from destinations hit these caches, thus avoiding costly source retransmissions; and JTP fairly allocates bandwidth among flows by backing off the sending rate of a source to account for in-network retransmissions on its behalf. Analysis and extensive simulations demonstrate the energy gains of JTP over one-size-fits-all transport protocols.
