摘　　要：提出一种基于模糊逻辑的链路信任安全路由(Fuzzy logic-Link Trusted-based Secure Routing,FLTSR).先利用直接信任和间接信任估计FLTSR路由节点的总体信任值,再将链路质量和构建链路两个节点的总体信任值作为模糊逻辑系统的输入,最后由模糊逻辑系统中的规则库推演出链路的信任值,从而降低恶意节点参与路由的概率,进而构建稳定的安全路由.仿真结果表明,提出的FLTSR路由能有效地提高对恶意节点的检测率和数据包的传输率.Fuzzy Logic-Link Trusted-based Secure Routing(FLTSR) is proposed in this paper.The FLTSR route first estimates the total trust value of the node using both direct and indirect trust.Then,link quality and the total trust value of the two nodes building the link are taken as the input of the fuzzy logic system,and the trust value of the link is deduced from the rule base in the fuzzy logic system,so as to reduce the probability of the malicious node participating in the routing,and then a stable and secure route is constructed.Simulation results show that the proposed FLTSR route can effectively improve the detection rate of malicious nodes and increase the packet transmission rate.
