Une nouvelle approche de clustering pour améliorer les performances des réseaux de capteurs sans fil.

Abstract

The use of wireless sensor networks in several areas has prompted researchers to propose energy-efficient routing protocols to ensure long network lifetime as the networks are considered energy-autonomy networks. In this work, we proposed a new routing scheme based on the clustering approach. This protocol organizes the network into clusters by considering the distance between the nodes and uses a routing scheme based on an improved greedy approach (Greedy Forwarding) to route data from a source node to the base station. This routing scheme establishes paths from clusterhead to clusterhead (CH-to-CH) until the base station, which reduces ennergy consumption and therefore increases network lifetime.
