Game Theory Based NanoMAC Protocol for Inter Cluster Wireless Sensor Network

Abstract

Wireless sensor networks (WSNs) are ad hoc topologies with highly dynamic traffic rates offered. In this network, sensor nodes are often battery operated and the power consumption become more important issue. The medium access control (MAC) protocol designed for the network must be stable and consume less energy. The available non-persistent carrier sense multiple access (np-CSMA) based MAC protocol is not suitable for WSN because of higher possibility of frame collisions and consume more energy at variable traffic rates. To overcome this limitation, the carrier sense multiple access protocol with collision avoidance (CSMA/CA) called nanoMAC is used. The nanoMAC is more suitable for WSN to achieve high data and energy efficiency. In this paper Game theory based nanoMAC (G-nanoMAC) protocol and the performance is evaluated for the energy consumption and delay to maximize the lifetime of the multihop network. Simulation results shows that using game based nanoMAC protocol in WSN for multihop forwarding is more energy efficient
