On the basis of conventional clustering routing algorithm, a Game-oriented algorithm is proposed for adaptively optimizing the routing in wireless sensor network. In this network, the routing path is built from source cluster to base station according to the primary principles of both minimizing the overall energy consumption and prolonging individual life span. The communication mode between cluster heads can be self-adaptively selected among the direct, relaying and collaborative ways. During the routing process, routing selection and routing forwarding algorithms are introduced so that our algorithm cannot only identify the most reliable next-hop node through pairwise game but also adaptively select the most energy-efficient means of communication. Simulation results show that the proposed routing algorithm can effectively reduce communication energy consumption and prolong network lifetime.
