Game theory based ETDMA for intra-cluster wireless sensor network

Wireless sensor networks (WSNs) consist of large number of sensor nodes which have adhoc topology. Sensor nodes are usually battery operated and their operational lifetime should be maximized for various applications, therefore energy consumption of the node is a critical issue. In this paper, a game theoretic energy efficient MAC protocol named as game based energy efficient TDMA (G-ETDMA) for intra-cluster WSN is proposed to reduce the energy consumption of the nodes. Performance of G-ETDMA is evaluated in terms of energy consumption and compared with conventional MAC schemes. Simulation results show that the G-ETDMA MAC protocol considerably reduces the energy consumption to maximize the lifetime of the sensor network.
