摘要:

综合移动自组织网络(MANET)路由节点的状态和行为因素,提出了一种基于多属性决策的MANET路由动态信任模型(MDF-Trust)。该信任模型采用多属性决策理论量化路由节点的状态和行为等信任决策因素并对MANET路由节点的信任进行评价,通过引入推荐信任度和推荐节点搜索算法遏制恶意节点的欺骗行为。仿真实验结果表明,该信任模型能准确地反映MANET路由节点的信任变化,具有更好的动态响应能力,并且在存在欺骗节点的情况下有更高的分组投递数和更低的网络时延。

Abstract:

A dynamic trust model in mobile Ad hoc network (MANET) based on multiple factors decision (MDF-Trust) was proposed. Through quantifying the decision factors of state and behavior of the node, the routing node trust by multiple factors decision theory was evaluated. The deceptive behavior of malicious node was restrained by the trust model when introducing recommendation credibility and recommendation node searching algorithm. Simulation shows that the proposed trust model can reflect the node's trust changes accurately with better dynamic response ability with higher number of packet delivery and lower delay in the circumstance of existing deception nodes.

Key words: mobile Ad hoc network, multiple factors decision, dynamic trust model, routing node trust
