Abstract : In Wireless Sensor Networks, usually sensor nodes suffer from limited battery power. It is a difficult task to work with sensor nodes in an energy-efficient way. To work with this claim, in this work authors propose a ClusterHead (CH) selection approach named as Energy-Efficient Approach to select Cluster Head (ECS) which works with two algorithms: ECHSA-1 and ECHSA-2. The ECHSA-1 algorithm works with Nash Equilibrium (NE) decision of the game theory. Here, each player in a game is considered as a cluster for both ECHSA-1 and ECHSA-2. The players select their best strategy according to the node’s residual energy. But, ECHSA-1 algorithm suffers from multiple NEs. So, ECHSA-2 algorithm is proposed based on the Sub-game Perfect Nash Equilibrium (SPNE). Based on the SPNE decision, CHs are selected. The simulation results show that the network lifetime is longer in case of ECS as compared to the baseline algorithms such as UCR, DEEC, and BEEG.
