Ad Hoc网络先应式路由算法(Proactive Routing Algorithm)具有寻由时延小,拓扑维护及时的优点,适合在网络负载较大的环境下高效运行.本文针对路由维护机制,以减少协议开销和寻由错误报文为目标,提出了基于Ad Hoc网络的先应式路由维护机制优化模型.通过对优化模型的相关参数讨论,得出如下结论:1.先应式路由协议的最优更新时间周期具有“逆向稳定性”;2.节点数目n与更新系数h有比例关系n→h3/2.通过模型求解和仿真结果相比较,验证了模型的正确性.优化模型的研究为先应式路由算法更新机制和算法的可扩展性支持提供了理论依据. 展开更多

Subarea Tree Routing (STR), a new routing protocol for multi-hop wireless ad hoc networks, is proposed. The novelty of the STR protocol is to divide the whole network into many subareas constructed as a result of establishing subarea trees. Its main idea is to identify root nodes by manual configuration or auto-discovery process firstly, then the root nodes originate the process of establishing subarea trees, and finally each node either joins in a subarea tree or become an interconnect node. STR belongs to hierarchical routing protocol and does not attempt to consistently maintain routing information in every node. Furthermore, through the use of tree’s intrinsic routing function, the STR protocol exhibits hybrid behavior of proactive and on-demand routing protocols. We prove the correctness of STR, and our simulation results show that the pro-posed scheme achieves lower route discovery delays, lower route discovery load and better performance of normalized routing load in large, mobile, ad hoc networks as compared with AODV. 展开更多
