A Review on Different Cluster Head Selection Methods for Improving The Lifetime of Wireless Sensor Network

Abstract
Increasing the life time of sensor nodes in the wireless sensor network is the fundamental aim of most of the recent researches in this area. Different routing protocols have been evolved in the last decade aiming at this task and various suggestions have been discussed in literatures. Selection of the Cluster Head is one of the key processes which determines the lifetime of the node. In this paper, different methods of Cluster Head selection have been discussed focusing on few parameters which affect the performance of the sensor network.
