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.frClustering, Greey Forwarding, K-means, Wireless Sensor Networks, Routing.Clustering, Greey Forwarding, K-means, Réseaux de capteurs, RoutageUne nouvelle approche de clustering pour améliorer les performances des réseaux de capteurs sans fil.Thesis
