A Novel Approach for Energy-Efficient of WSN Using PEGASIS Protocol

Abstract

Wireless Sensor Networks (WSNs) have hardware and software limitations and are deployed in hostile environments. The problem of energy consumption in WSNs has become a very important axis of research. To obtain good performance in terms of the lifetime of the WSN, several routing protocols have been proposed. We present in this article a new approach for the energy efficiency of WSN by using the PEGASIS (Power Efficient Gathering In Sensor Information Systems) routing protocol in order to reduce sensor energy consumption and to achieve good performance in terms of the lifetime of the network in WSN. The simulation results have shown that our proposed protocol excels regarding energy consumption in wireless sensor networks, resulting in an extension of a lifetime for the network. We simulated the proposed technique compared with traditional LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol using MATLAB environment
