The Inter-Cluster Routing Algorithm in Wireless Sensor Network Based on the Game Theory

In the resource constraint Wireless Sensor Network(WSN), link quality and node residual energy are the key factors that need to be considered in the routing problem. This paper proposes a routing algorithm based on game theory. Firs it sets up the game model based on the Quality of Service(QoS) and node residual energy. Then it shows that the game has a unique Nash equilibrium solution, and analyses the feasibility of the algorithm. The simulation results show that the proposed model could optimize the QoS, reduce the energy consumption of nodes and prolong the network life time.
