Performance Evaluation of Energy Efficient Clusterbased Routing Protocol in Wireless Sensor Networks

Energy efficient is the most important issue that must be solved in designing a qualified routing protocol for wireless sensor networks (WSNs) is how to save sensor node energy while meeting the needs of applications/users as the sensor nodes are battery limited. . There are number of various routing protocols have been proposed to optimize the efficiency of WSNs. From these protocols, cluster based routing algorithms have achieved more significant and increasing the life time of the WSN even the nodes are in mobile state. In this paper, we introduce an energy efficient clustering algorithm for sensor networks based on the LEACH protocol. LEACH (Low Energy Adaptive Clustering Hierarchy) is one of popular cluster-based structures, which has been widely proposed in wireless sensor networks. LEACH uses a TDMA based MAC protocol, and in order to maintain balanced energy consumption. This paper mainly compares the clustering protocols, namely LEACH, LEACH-C, MTE and Stats-Clustering using NS2 tool for analyze the performance of the simulation results with different metrics like Network Life time, received packet and Energy Consumption.
