An Efficient Cluster Head Selection Strategy for Wireless Sensor Network

A wireless sensor network can be divided into several clusters. Each cluster has a number of sensors nodes and one of the nodes is elected as the coordinator, termed as head. The head is responsible for not the general mission but also collecting the sensed data of other nodes and routing to the sink. Accordingly, the energy-consumption is higher than other nodes. Therefore, the head selection will affect the life-time of a network. In this study, we consider the factor of energy consumption to determine the head. Simulation results demonstrate our study can enlarge the life time for wireless sensor networks.
