一种基于博弈的移动自组网节点协作机制研究

Research on a Kind of Game Theory Based Node Cooperation Mechanism in Mobile Ad Hoc Networks

针对移动自组网中自私节点拒绝路由和转发服务请求,影响整体网络性能的问题进行研究,基于经济学中提出的博弈理论,提出了一种引入节点协作自主性的节点协作机制,将节点按其协作意愿进行节点类别划分,对不同个性节点采取不同的行为策略,并利用修正因子进行协作激励和惩罚自私,在一定程度上解决节点的协作问题。

Aiming at solving the problem of selfish node refusing route and forward service requests in mobile Ad Hoc network, based on game theory in economics, proposes a cooperation mechanism with node cooperation autonomy. The nodes are divided into several types ac- cording to the wishes of the cooperation, and nodes of different types act different strategies. Some correction factors are used to encourage cooperation and punish selfishness. To a certain extent, addresses the issue of node cooperation in mobile Ad Hoc networks.
