无线Mesh网络中激励机制研究

Research on Incentive Mechanism for Wireless Mesh Networks

为了激励无线Mesh网络中自私节点转发数据,通过分析节点自私行为激励的原因和目标,将适用于无线Mesh网络中对节点自私行为的四类激励机制进行比较.讨论了无线Mesh网络博弈模型,并对无线Mesh网络中重复博弈模型进行理论分析.针对节点的自私行为提出了基于博弈论与信誉相结合的激励方案.仿真实验表明,该方案不仅降低了基于信誉的复杂度又能有效激励更多自私节点转发数据,从而提高了网络的整体性能.

In order to motivate selfish nodes to forward data in wireless mesh networks, through analyze the reason and object of the nodes selfish behavior. Comparison four types of incentive mechanism of the nodes selfish behavior in wireless mesh networks. The discussion of game theory in wireless mesh networks and the theoretical analysis of repeated game theory are another emphasis. An incentive mechanism is proposed combined game theory and reputation ~or the selfish behavior of nodes. The simulation results show that the strategy not only reduces the complex of the reputation but also can effectively motivate more selfish nodes forwarding data which improve the overall performance of the wireless mesh networks.
