摘　　要：路由协议是移动Ad Hoc网络中的一个重要部分,很多研究表明,Ad Hoc网络的特性使得传统的路由协议不再有效。在简述动态源路由协议DSR及其存在的问题后,着重介绍了具有安全路由发现、多路由的使用和提高路由缓存管理的S-DSR协议的设计,并对S-DSR与DSR就包传递率、包截获率等进行了性能仿真与分析比较。Eouting protocol in dynamic （multi--hop） ad hoc networks is a great important issue for network efficiency and performance. Many research works show that the dynamic features of mobile ad hoc networks deteriorate the effectiveness of the traditional routing protocols. This work begins with a brief introduction of the dynamic source routing （DSR,） and the analyses of its limitations. On this basis, a secure DSR protocol （S--DSR,） is designed, in consideration of a secure routing discovery strategy and multi--path routing mechanism. Our simulation experiments demonstrate that the S-DSR achieves the better performance compared to the existing DSR, in terms of packet delivery ratio, packet capture ratio, ect.
