摘要： 针对移动自组织网络路由的可靠运行和安全保障问题,提出一种基于Dempster-Shafer 证据理论的节点信任评估模型。利用历史交互信息计算直接信任度,通过邻居节点的推荐度量值获取间接信任度。对直接和间接信任度进行权重修正后根据Dempster 组合规则合成,得到节点全局信任度。利用该模型对优化链络状态路由协议的多点中继技术进行优化,设计改进的路由协议TOLSR。仿真结果表明,TOLSR 协议能发现和抑制网络的自私节点和恶意节点,有效提高移动自组织网络的可靠性,证明了该信任度评估模型的有效性和合理性。

Abstract: Specific to reliability and security problems in Mobile Ad Hoc Network(MANET),a trust evaluation model based on Dempster-Shafer(D-S) evidence theory is proposed. Direct trust degree is calculated with historical interaction information and indirect trust is obtained from neighbor nodes’ commendations. The direct trust degree and indirect trust are combined according to Dempster combination rule after being amended with weight,to obtain node’s comprehensive trust finally. On this basis,it optimizes the Multi-point Relaying (MPR) technology in Optimized Link State Routing Protocol(OLSR),and proposes an improved routing protocol (TOLSR). Simulation result shows that the model can discoveries selfish nodes and malicious nodes,thus effectively improves the reliability of MANET,which also proves the validity and rationality of the trust evaluation model.

Key words: Mobile Ad Hoc Network(MANET), selfish node, Dempster-Shafer(D-S) evidence theory, trust degree evaluation, Optimized Link State Routing Protocol(OLSR), Multi-point Relaying(MPR)node
