| Abstract: | 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 success 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. |
