Abstract: Wireless Sensor Networks (WSNs) contains group of sensors which are used for wide variety of applications. Many constraints in which WSNs needs to operate like limited battery capacity, coverage issues and these constraints needs to be crafted carefully to maintain minimal energy consumption and improving Network Lifetime. During routing process dead lock situations occur due to faster drain out battery levels for neighbour’s nodes which makes the WSN network to die. In order to minimize such cases Modified Game Theory Energy Balancing with Fixed Relay Stations (MGTEB-FR) at optimized points in the WSN is proposed. Once the neighbour nodes contain one of the relay stations it takes care of sending the packets at a faster rate to destination thereby allowing lesser load on the sensor nodes for data transmission which reduces the energy consumption levels and increases lifetime. The MGTEB-FR is compared with existing techniques namely Game Theory Energy Balancing, Energy Game Theory, Coverage Game Theory and Randomized Algorithm. The performance of MGTEB-FR is studied for various radio propagation models.
