| 摘 要： | 在介绍和分析认证路由协议ARAN后，发现其存在着无法防范认证节点丢弃数据包或者不参与到路由发送中去等弱点。因此，本文在ARAN的基础上提出了一种基于全局信誉机制的认证路由协议（RARAN）。其主要思想是计算和存储节点的全局信誉值并以此作为路由选择的依据来促进节点间的相互合作。仿真结果显示，在RARAN网络中存在自私节点的的情况下，与ARAN相比，在协议的安全性和网络的包传输率等方面具有更好的性能。

| Abstract: | After an introduction and thorough analysis of the Authenticated Routing for Ad hoc Networks(ARAN),we find that an authenticated node could disturb networks by dropping packets or not participating in this routing protocol.In order to deal with this kind of vulnerability we propose an improvement on the ARAN using global reputation mechanism(RARAN).The improved protocol computes and stores the global reputation values of the nodes,and uses it as the basis of routing choice.Through this kind of method,it enables the protocol to stimulate the nodes to cooperate with each other.Our simulation results showed that RARAN achieves more securities and a higher throughput compared with ARAN in the presence of selfish nodes. |
