چکیده

Wireless Sensor Networks have some well known features such as low battery consumption, changing topology awareness, open environment, non reliable radio links, etc. In this paper, we investigate the benefits of Network Coding Wireless Sensor networking, especially resiliency. One of our main concern is the resiliency in Wireless Sensor Networks. We have seen that resiliency could be described as a multi dimensional metric [4, 3, 5] taking parameters such as Average Delivery Ratio, Delay Efficiency, Energy Efficiency, Average Throughput and Delivery Fairness into account. Resiliency can then be graphically represented as a kiviat diagram created by the previous weighted parameters. In order to introduce these metrics, previous works have been leaded on the Random Gradient Based Routing, which proved good resiliency in malicious environment. We look for seeing the improvements in term of resiliency, when adding network coding in the Random Gradient Based Routing with malicious nodes.

L’une de nos préoccupations concerne la résilience des Réseaux de Capteurs Sans Fils. Il a été montré que la résilience pouvait être représentée comme une métrique à plusieurs dimensions [4, 3, 5] ayant pour paramètres le Taux de Livraison Moyen, le Délai Moyen, l’Efficacité Énergétique, le Débit Moyen et la Distribution des Livraisons. La résilience peut être représentée sous forme d’un diagramme de Kiviat ayant pour branches les précédents paramètres. Afin de présenter la résilience, des travaux antérieurs ont été effectués sur le protocole Random Gradient Based Routing, qui présente une bonne résilience en environnement malveillant. Nous voulons observer les améliorations en terme de résilience que l’introduction de Codage Réseau sur le précédent protocole apporte en fonction du nombre de nœuds malveillants.

Data Dissemination in Wireless Sensor Networks with Network Coding

In wireless sensor networks (WSNs), it is often necessary to update the software running on sensors, which requires reliable dissemination of large data objects to each sensor with energy efficiency. During data dissemination, due to sleep scheduling designed for energy efficiency, some sensors may not receive some packets at some time slots. In the meantime, due to the unreliability of wireles...
