摘　　要：在无线传感器网络(WSNs)中,由于节点数量较多,使得无线信道资源极其有限,如何分配有限的无线信道资源一直是WSNs和无线通信网络的研究热点之一。博弈论是一种有效的资源配置方法,以博弈论中的抓钱博弈为基础,引入了信誉机制和权重机制用于分配无线信道资源。信誉机制用于实现用户使用信道的公平性,权重机制用来增加算法的真实性和信道的利用率。使用Matlab作为仿真工具对使用该算法两个用户进行仿真分析。仿真结果表明:该算法在提高信道资源利用率的同时,保证了信道使用的公平性。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.
