| 摘 要： | 针对Ad Hoc网络匿名路由算法研究局限于路由发现过程的问题,该文探讨了路由维护过程。将本地路由修复机制引入到匿名路由中,提出了一种高效的修复算法。该算法能够在路由失效后通过局部发现,快速重建路由,极大地提高了路由算法的性能。理论分析说明了该算法的安全性。仿真表明:在引入本地修复后,路由算法的传输延迟在节点平均移动速度为20 m/s时下降13%,分组投递成功率提高1.5%,控制报文减少约15%;且节点移动速度越快,本地修复机制的优越性越明显。

| Abstract: | In view of the limitation of the researches on anonymous routing algorithm in Ad Hoc networks in the routing discovery procedure,the routing maintenance procedure is investigated.The local repair mechanism is introduced into the anonymous routing and a secure and efficient algorithm is proposed.It can repair the route rapidly based on a local discovery,significantly improving the performance of the anonymous routing algorithm.Theoretic analysis proves the security.Simulation shows that when the average spee... |
