In wireless sensor networks（ WSNs）

wireless channel resource is limited because there are so many nodes. It become an important problem that how to allocate the limited channel resources in WSNs and wireless communication networks. Game Theory is an efficient method to allocate resources

based on grasping money game

reputation and weight mechanism are intoduced. Reputation mechanism is used to achieve fairness for users

and weight mechanism is joined to increase the authenticity of the algorithm and the utilization of channel. Matlab is used as simulation tool to simulate and analyze two users who use the proposed algorithm. Simulation results show that this algorithm can improve channel utilization efficiency

at the same time

guarantee fairness of channel access.
