ENHANCEMENT OF SENSOR NODE EFFICIENCY IN HETEROGENEOUS NETWORK USING DISTANCE (SEP) IN WSN

In this research we reflect the Wireless Sensor Networks (WSNs) have seen an increased interest in various applications like border field security, disaster management and medical applications. So, large number of sensor nodes are deployed for such applications, which can work autonomously. Due to small power batteries in WSNs, efficient utilization of battery power is an important factor. Clustering is an efficient technique to extend life time of sensor networks by reducing the energy consumption. In this paper, we propose a protocol; Distance based Stable Election Protocol (D-SEP). Our CH selection scheme is based on the weighted election probabilities of each node according to the Energy Consumption (EC) of each node.Our simulation results show that our proposed protocol, ECRSEP outperforms all these protocols in terms of network stability and network lifetime
