摘　　要：由于网络拓扑的开放性和缺乏集中管理,移动Ad hoc网络容易遭受恶意节点的攻击。借助层次分析法和模糊逻辑规则预测方法,建立一种信任管理模型,并在多径OLSR路由协议的基础上提出基于信任的多径路由协议TMP-OLSR。该协议可以剔除恶意节点以获得从源节点到目的节点可靠路径。仿真结果表明:和MP-OLSR协议相比,TMP-OLSR协议能够有效地检测恶意节点,降低丢包率,提高网络吞吐量。Owning to the openness of network topology and the absence of centralised administration,mobile Ad hoc network is vulnerable to attacks from malicious nodes. We build a trust management model by using analytic hierarchy process and fuzzy logic rules prediction method. Based on the multipath OLSR,we propose a new trust-based multipath routing protocol—TMP-OLSR. It can eliminate the malicious nodes in order to obtain a reliable path between source node and the destination node. Simulation result shows that compared with MP-OLSR protocol,TMP-OLSR can effectively detect the malicious nodes,decrease packet drop ratio and increase network throughput.
