| 摘 要： | 针对Ad Hoc网络中的多跳通信需要自私节点间的数据分组中继,不使用协作的激励机制,提出了一种基于博弈论的解决方案。该方案通过建立节点间中继协作的无限次重复博弈模型,给出此博弈的纳什均衡中继策略TFT,并对其群体稳定性进行了分析。通过仿真表明,各节点根据网络拓扑结构变化速度的快慢调整TFT策略的宽容因子g,能够有效激励节点间的中继协作。

| Abstract: | To enhance the packets forwarding cooperation between selfish nodes in Ad hoc networks without the incentive mechanisms,a solution based on game theory is developed.Modeling the forwarding cooperation as infinitely repeated game,a TFT forwarding strategy is presented as NE(Nash equilibrium) for selfish nodes.The colony stability of the NE strategy is analyzed and testified.Simulation indicates that adjusting the generosity factor g under the TFT scheme according to the changing speed of the network topology results in effectively stimulated cooperation between the selfish nodes. |
