认知 Ad-Hoc 网络中一种基于稳定性和时延的路由协议
A stability and delay based routing protocol for cognitive radio Ad Hoc networks
摘要
Abstract
In the future cognitive Ad-Hoc networks,the activities of the primary users will cause great influence on the sta-bility of multiple hops routes between cognitive users.To ensure the route stability and reduce the route latency between cognitive users,a stability and delay based routing protocol is proposed.In the protocol the concept of stability factor is in-troduced,only the paths under the stability constraint can be the candidate routes.Then the transmission delay is used as a metric to select the best route from those candidate routes.First,the superiority of the proposed routing selection strategy is demonstrated through a sample topology model.Then,the latency and route stability in cognitive radio Ad-Hoc networks are detailed analyzed.Last,improvements are made on the traditional AODV protocol to realize the proposed channel allocation and routing selection strategy.Simulation results show that the proposed protocol has a better performance on route stability and end to end delay both under different source and destination distances,and different primary user activities.关键词
