摘要
为提高无线自组织网络分簇管理的安全性,提出一种基于网格的Ad Hoc网络匿名组播路由协议。通过设置簇首非周期性随机发送hello消息机制,降低被窃听的成功率;为防止窃听者通过分析消息格式获得有效信息,为自组织网络的各种消息设计统一格式;新节点入簇时,无需向簇首发送请求即可与网格中的其它节点建立链接与路由。协议设计的匿名组播方法可全面保证网络节点的匿名性与安全性。仿真结果表明,与其它协议相比,该协议具有较好的链接性与匿名性,较低的能耗、路由建立延时和较高的分组数据包投递率。
To improve the security of cluster management in wireless Ad Hoc networks, a mesh-based anonymous Ad Hoc multicast routing protocol network was presented. Random cluster head aperiodic message sending hello mechanism was utilized to reduce the chances of being tapped successfully. A uniform format was designed for a variety of messages of Ad Hoc network to prevent eavesdroppers from obtaining useful information through the analysis of message formats. When the new node was in the cluster, it was not necessary to send a request to the cluster head. Anonymous multicast protocol design can guarantee the anonymity and security of network nodes. Simulation results show that the proposed protocol not only has better linkability and anonymity, and lower power consumption, latency as well as higher packet delivery ratio compared with other protocols.
