摘　　要：首先介绍了非合作博弈均衡(纳什均衡),并将纳什均衡的基本原理应用到Ad hoc网络中节点间的数据传输中,对采用纳什均衡的几种常用的策略也做了介绍,并着重对其中的TFT策略进行了讨论。并用"Small World"这一概念替代传统的"最短路径"概念,同时对Small-World做了介绍。随后针对Ad hoc网络的某些拓扑结构,将"纳什均衡"策略和目前其他一些激励机制进行了比较和讨论。认为在目前的Ad hoc网络中,非合作博弈均衡(纳什均衡)是比较理想,比较简单的一种分组传输策略。The paper introduces the Nash equilibrium firstly, then applies its basic principle to the packet transmission of wireless Ad hoe network, and also shows some common strategy of Nash equilibrium, focusing on the TFT. The ＂shortest path＂ is replaced by ＂Small World＂ concept and some introduction to Small World is done. The Nash equilibrium is compared with some other stimulant mechanism according to some topology. And in current status, Nash equilibrium is an appropriate method for the packet transferring in Ad hoc network.
