无线多跳网络中的节点通常都具有自主性和资源受限的特点,因此开展效用研究具有重要意义.论文提出将声誉机制与价格机制相结合,并应用博弈理论促使发送端同时兼顾所预付的通信价格与转发节点的可信度.根据博弈理论对无线多跳网络中节点行为进行了建模分析.最后,本文给出纳什均衡的存在条件,并且通过仿真实验证实了以誉价比机制作为发送端决策因素的合理性.
The nodes in wireless multi-hop networks usually have the characteristics of autonomy and limited resources, so it is of great significance to carry out utility research.The thesis proposes to combine the reputation mechanism with the price mechanism and use the game theory to make the sender balance both the prepaid Communication price and the credibility of forwarding nodes.According to the game theory, the behavior of nodes in wireless multi-hop network is modeled and analyzed.Finally, the paper presents the existence conditions of Nash equilibrium, and through the simulation experiments, The rationality of the decision-making factors at the sender.
