摘要
无线Ad Hoc网络中,节点的移动可能引起路由失效,从而导致路由重建,而这会降低网络的性能。针对这个问题,把图论中"节点度数"的思想引入到无线Ad hoc网络路由算法中,在AODV基础上提出了SRP路由协议。SRP根据"节点度数"和路由跳数寻找稳定路由,提高了本地路由修复的成功率,减小了源节点路由重建的次数,提供了QoS保证。该协议是一种同时兼顾路由稳定和QoS的路由协议。
In wireless Ad Hoc networks, the mobility of nodes may cause route failure that leads to route rediscovery. Frequent route rediscoveries degrade the performance of networks. To solve this issue, the concept of node degree in graph theory was introduced into Ad Hoc routing algorithm, and present a stable routing protocol (SRP) based on AODV routing. SRP finds stable routing based on node degrees and hops in a route. It enhances the suc- cess probability of local route repair, reduces the times of route rediscovery from source node, and supports QoS. Therefore, SRP is a routing protocol which can guarantee both routing stability and QoS.
