在无线Ad Hoc网络中,源节点和目的节点互相通信需要中继节点的支持,但节点是理性的,所以可能会拒绝转发请求。这里就节点之间存在的合作问题,对针锋相对策略、冷酷策略、完全合作策略、宽恕的针锋相对策略、严厉针锋相对策略进行了纳什均衡分析。理论分析可知,针锋相对策略相对于其他策略更具优势,因为它的阈值较低。
在無線Ad Hoc網絡中,源節點和目的節點互相通信需要中繼節點的支持,但節點是理性的,所以可能會拒絕轉髮請求。這裏就節點之間存在的閤作問題,對針鋒相對策略、冷酷策略、完全閤作策略、寬恕的針鋒相對策略、嚴厲針鋒相對策略進行瞭納什均衡分析。理論分析可知,針鋒相對策略相對于其他策略更具優勢,因為它的閾值較低。

In wireless Ad Hoc network,the intercommunication between the source and destination nodes needs the sup?port of relay node. Since the node is rational,it may refuse the forwarding requests. For the cooperation problem among the nodes,the tit?for?tat strategy,grim strategy,full cooperation strategy,tolerant tit?for?tat strategy and severe tit?for?tat strategy are analyzed with Nash equilibrium. According to the theoretical analysis,the tit?for?tat strategy is more advantageous than other strategies because of its low threshold value.
