Enhanced Threshold Sensitive Stable Election Protocol for Heterogeneous Wireless Sensor Network - 2015

Research Area:  Wireless Sensor Networks


The major challenges in wireless sensor network include energy conservation, node life time, stability and throughput of network and its node. Clustering is widely used to reduce the energy consumption and to improve the stability of the network. The efficient routing protocol in a cluster plays an important role in energy saving and stability of the cluster and its nodes. Enhance Threshold Sensitive Stable Election Protocol (ETSSEP) is proposed for heterogeneous wireless sensor network in the paper. It is based on dynamically changing cluster head election probability. It selects cluster heads on the basis of residual energy level of nodes and minimum number of clusters per round. The ETSSEP is simulated using MATLAB and found that it performs better than Stable Election Protocol (SEP) and Threshold Sensitive Stable Election protocol (TSEP) in terms of stability and network lifetime. ETSSEP builds more stable routing environment as compared TSEP and SEP. It is also found that ETSSEP stability is increased by 33.5 % in comparison to TSEP and more than twice in comparison to SEP. The overall lifetime of ETSSEP is also increased by 37.79 % in comparison to TSEP and about thrice in comparison to SEP.
