The advancements in wireless communication have dictated the need of wireless sensor network (WSN) with infrastructure free support to intervene with hostile environment. The principal deliberation of WSN has been to save energy and to enhance the lifetime of the network. The data transmitted from the sensor nodes is highly vulnerable to error in a wireless environment which increases the transmit power. Error control coding (ECC) schemes can perk up the system performance and has an impact on energy consumption. In addition, a proper node deployment scheme minimizes the number of interfering nodes in the network. Moreover, channel fading and interference which increases the energy consumption of sensor nodes are mitigated by employing diversity techniques. Virtual multiple input multiple output (VMIMO) schemes that provide diversity gain are used to reduce the retransmission probability so as to improve energy savings. In this paper, an attempt has been made to develop a game theoretic framework considering ECC in hexagonally deployed VMIMO WSN.
