Abstract
Abstract: A wireless sensor network (WSN) consists of inexpensive power constrained sensor nodes collectingdata from the sensing area and transmits data towards the base station in a synergetic way. The basic goal ofwireless sensor network is to enhance the node lifespan, stability period and throughput of network. The WSNnodes are restricted by energy, storage capacity, and computing power. So clustering is used to improve lifetimeand stability. Cluster routing protocol plays an important role for improvement of energy and stability of thenetwork. In this paper a new technique Enhance Threshold Sensitive Stable Election Protocol (ETSEP) isproposed and evaluated for heterogeneous wireless sensor network. In this technique cluster head electionprobability dynamically changes. The ETSEP is simulated using MATLAB and found that it performs better thanStable Election Protocol (SEP) ,Threshold Sensitive Stable Election protocol (TSEP) and Zonal Stable ElectionProtocol(ZSEP) in terms of stability and network lifetime. ETSEP builds more stable routing environment ascompared to SEP, TSEP and ZSEP. Simulation results shows that our protocol performs better than SEP, TSEPand ZSEP.
