Advance Stable Election Protocol in Wireless Sensor Network

Abstract

Wireless sensor network (WSN) is an emerging research field. There are large numbers of sensors that collect and send data to base station. Saving energy by using various routing techniques is a challenge. Clustering is main technique used for this. Various protocols like SEP (Stable Election Protocol) and ESEP (Extended Stable Election Protocol) are clustering based heterogeneous aware protocols. In this paper, a new protocol ASEP (Advance Stable Election Protocol) has been proposed based on SEP. This is based on changing more efficiently and dynamically the cluster head election probability. Performance of this protocol has been evaluated in MATLAB and graphical results have been shown. The performance of ASEP is better than SEP in form of first node dies and total number of packets delivered.
