摘要：Wireless Sensor Networks (WSNs) are been used in many applications such as: health care monitoring, environmental/Earth sensing, industrial monitoring, data logging. But in order to reach their potential, researchers must find solution to some difficulties which are slowing down the wide spread use of these networks. These difficulties are inherent to their constrained specificities which require adapted solutions unrelated to classical wire networks. The number of packets sent/received by WSN has a huge impact on the amount of energy consumed. In order to reduce this number and to ensure at the same time WSN successful operation, hierarchical clustering protocols have been developed. In this paper, we present Well Balanced TEEN (WB-TEEN) and Well Balanced with Multi-hops intra-cluster TEEN (WBM-TEEN): two hierarchical routing protocols, based on nodes clustering and improving the well-known protocol Threshold sensitive Energy Efficient sensor Network protocol (TEEN). This improvement is accomplished in a way such that the number of nodes in each cluster is balanced and the total energy consumption between sensor nodes and cluster heads is minimized by using multi-hops intra-cluster communication. Simulation results (using NS2 simulator) show that the proposed protocols exhibit better performance than Low Energy Adaptive Clustering Hierarchy (LEACH) and TEEN in terms of energy consumption and network lifetime prolongation.
