摘要: 随着大规模无线多跳自组网在军队通信、应急通信等领域的广泛应用,域路由协议(ZRP)作为一种混合路由协议,其灵活的路由发现和维护策略,使其在大规模网络中的应用受到了更多的关注。ZRP的域内路由协议以及域间路由协议的选取,对协议整体性能影响巨大。面向具有一定拓扑变化的大规模无线多跳自组网,基于传统ZRP框架,优化设计得到改进的域路由协议。改进协议中,域内路由协议采用具有更高路由有效性以及较小资源消耗的主动路由策略,域间路由协议则通过增加过期路由缓存机制降低网络控制开销。通过建模分析验证了改进协议的域内路由具有更高的有效性;通过软件模拟平台NS2仿真,验证了改进协议具有更优的性能。

Abstract: Since the large-scale wireless multi-hop ad hoc networks have been widely used in military communications, emergency communications and other fields, the zone routing protocol (ZRP), as a hybrid routing protocol, has been paid more attention in the large scale network application because of its more flexible routing discovery and maintenance strategy. The selection of intrazone routing protocol and interzone routing protocol of ZRP has great impact on the overall protocol performance. An improved zone routing protocol based on the traditional ZRP framework is proposed for large-scale wireless multi-hop ad hoc network that has certain topological changes. In the improved protocol, the intrazone routing protocol uses a more effective and less resource consumption routing strategy, and the interzone routing protocol uses an expired routing cache mechanism to reduce network overhead. The modeling and analysis results show that the improved routing protocol has higher validity. It is verified through NS2 simulation that the improved protocol has better performance. Key
