A game theoretic method, called the first price sealed auction game, was introduced to control routing overhead in wireless sensor networks in this paper. The players of the game are the wireless nodes with set of strategies (forward or not). The game is played whenever an arbitrary node in the network forwards packets. In order for the game to function, a multi-stage pricing game model is established, this provides the probability that the wireless nodes forward the receiving packets, and the payoff of all nodes can be optimize through choosing the best neighbour node. The simulations in NS2 showed that the pricing routing game model improves performance, not only decreasing the energy consumption, but also prolonging network life time. Finally the numerical analysis about nodes’ payoff is given through Matlab.
