Advancements in electronic and computer technologies have cemented the way for explosion of wireless sensor networks. A fundamental component of resource management is transmitter power control and an efficient power control technique is essential to support system quality and efficiency. The data transmitted from the sensor nodes is highly susceptible to error in a wireless environment which increases the transmit power. Error control coding (ECC) schemes can improve the system performance and has an impact on energy consumption as node energy is sturdily influenced by the modulation and error correction coding used. This paper proposes a power control solution for wireless sensor network (WSN) considering MIDRS code in the analytical setting of a game theoretic approach. The game is formulated as a utility maximizing distributed power control game while considering the pricing function and the existence of Nash equilibrium is premeditated. From the analysis it is evident that the system is power stable only if the nodes comply with certain transmit power. The utility of nodes employing RS and MIDRS codes is compared; the results show that employing MIDRS achieves the best response for the sensor nodes by consuming less power.
