| 摘 要： | 从演化博弈论的角度,提出一种能有效激励无线Ad Hoc网络节点参与数据分组中继协作的纳什均衡策略:G-TFT(Generous Tit for Tat).以节点中继的分组数与所需的能量开销为均衡点,建立了中继协作过程的单阶段博弈模型G,验证了节点的自私性动机,将G扩展为基于时闻序列、策略可转换的演化博弈R,并根据R的纳什均衡提出了协作激励策略G-TFT.仿真结果表明.通过调整宽容因子g,G-TFT能有效地激励节点参与中继协作.

| Abstract: | To enhance the packets forwarding cooperation between selfish nodes in mobile Ad Hoc networks,a solution based on evolution game theory is developed.Trading off between energy cost and packets forwarded,the forwarding cooperation is modeled as a single stage game,and the selfish motive of the nodes is testified.Extending the single stage game as an evolution game,a G-TFT(generous Tit for Tat) forwarding strategy is given as the Nash equilibrium for the selfish nodes.Simulation results show that adjusting th... |
