摘　　要：对Ad hoc网络中的DSR路由协议进行改进,提出了一种基于信任机制的安全DSR路由协议(SDSR).该协议利用节点的信任度来选择安全稳定的路径,限制了恶意节点参与路由建立过程,从而保证了路由传输的安全性和有效性.最后利用NS-2仿真软件对两种协议进行比较,结果表明SDSR协议的分组投递率优于DSR协议.For Ad hoc network, a Secure Dynamic Source Routing Protocol（SDSR） based on trust mechanism is proposed by improving DSR Routing Protocol. This protocol selected the safe and stability path by using node＇s trust probability, and Limited the malicious node in the route establish- ment process,so as to guarantee the safety and effectiveness of routing transmission, finally,two pro- tocol were compared by using NS-2 simulator, the results showed that SDSR protocol is superior to DSR protocol on packets delivery rate.
