The major issue which is of paramount importance in wireless sensor network is the power control since it is impossible to recharge or replace the batteries. Transmitting at high power not only reduces the lifetime of the nodes and that of the network, but it also introduces excessive interference. Therefore, every node should transmit at minimal power while maintaining connectivity and reducing interference. A proper node deployment scheme can lessen the complexity of problems in wireless sensor network like routing, data aggregation and communication. Moreover, it can extend the lifetime of WSNs by minimizing energy consumption. This paper analyses a game theoretic model taking into consideration the residual energy of the nodes in a homogenous wireless sensor network considering square grid, triangular and hexagonal topology schemes for sensor node deployment. The utility of the nodes that minimizes power consumption is analysed and the existence of Nash Equilibrium is studied. Simulation results show that, power consumption is reduced and throughput is maintained when hexagonal topology is considered.
