移动Ad hoc网络无基础设施仅靠网络节点之间的协作完成通信。其路由协议的安全性是研究热点之一。通过对按需路由协议AODV及其安全性进行分析,提出一种基于其安全性的改进方案。该方案采用隐藏身份寻找路由、唯一标识路由请求,对报文分组进行认证等方法,增强路由信息安全性。最后在NS2网络仿真平台上对该方案进行仿真和性能分析,结果表明改进方案的安全性有较大提高。
Mobile ad hoc networks have no infrastructure to communicate simply by collaboration between network nodes. The security of its routing protocol is one of the hot spots. By analyzing the on-demand routing protocol AODV and its security, an improved scheme based on its security is proposed. The scheme uses hidden identity to find routes, uniquely identifies routing requests, and authenticates packet packets to enhance the security of routing information. Finally, the simulation and performance analysis of the scheme on the NS2 network simulation platform show that the security of the improved scheme is greatly improved.
