摘　　要：无线通信网络在现代电信网中扮演重要角色,其无线信道环境使得对恶意节点的区分和恶意行为的防御变得较为困难。针对无线通信网络中的路由安全问题提出了一种相对独立于路由协议的可信路由框架,该框架以模糊多目标决策为基础,通过计算信任环路来实现信任拓扑控制,构建安全可信的路由,并最终实现该框架的高移植性,高扩展性,可方便灵活地应用于多种不同的网络。在半实物仿真平台上对提出的独立可信路由机制进行实现,仿真结果表明,文章提出的可信路由框架具有良好的性能,能有效防御网络中的恶意节点,为无线通信提供安全保障。Wireless networks play an important role in modern telecommunication systems.The wireless channel environment makes it difficult to detect malicious nodes and defend malicious behaviors.To solve the security problem in wireless networks,this paper proposes a novel trust framework which is independent of routing protocol.The framework uses fuzzy multi-objective decision making and topology control.In the proposed framework,the trust routing is based on the trust topology obtained by calculating trust circle.The framework has high flexibility and scalability,which can be applied to multiple different wireless networks.This paper also implements the proposed framework on a SITL（system in the loop） platform.Simulation results show that the proposed framework has excellent performance on defending malicious nodes and providing security for wireless networks.
