摘　　要：Ad Hoc网络是目前无线网络的一个流行趋势,但作为一种新兴无线网络,因其自身的特点,传统有线网络的安全技术并不完全适用于它,因此Ad Hoc网络的安全问题一直是一个研究的热点问题。深入分析了AODV协议及其路由发现、路由维持和路由修复过程。在此基础上,本文基于AODV协议提出了一种基于信任的安全路由协议(TBS-AODV),利用NS2仿真器对TBS-AODV协议进行了仿真,其结果表明TBS-AODV协议在付出一定的消耗代价后可以较好的避免灰洞、黑洞等攻击,可以实现安全可信的路由。Ad Hoc network is a popular trend of wireless network, but as a kind of new wireless network, it can not use the security technology of traditional network, plus the network＇s characteristic of being attacked easily, the security problem of Ad Hoc network is always the research hotspot. This paper deeply analyzed AODV protocol and its route finding, route maintaining and route repairing process, did the research of AODV~ route table structure, control group structure and related key technology, and proposed a trust -based secured routing protocol （TBS - AODV） based on the research of AODV. This paper used NS2 emulator to simulate TBS - AODV protocol, the result showd that TBS - AODV protocol could solve gray hole attack, black hole attack at a little bit more expense of spending, it could realize secured and trusted route.
