摘要
随着无线MESH网络技术的不断发展,客户端型MESH网络中,节点移动产生的网络拓扑变化问题影响着路由选择。因此,在考虑网络节点移动的前提下,如何选择稳定性路由是必须面对的问题。针对此问题,提出了一种基于移动预测的稳定性路由选择方法。该方法预测链路生存时间的同时,研究分析了平均传递时延和加权稳定度对网络稳定性的影响。所提方法明显优于传统路由选择的效果,能够提高路径稳定度,延长路径生存时间,实现稳定的路由选择。
With the development of wireless mesh networks technology,changing network topology effected by mobile nodes affects routing selection in client mesh networks.Therefore,the prerequisite for the mobility of the nodes,how to choose a stable routing is the problem what the mesh networks have to face.To solve this problem,a method based on mobility prediction of the stability is proposed in this paper.The schemes predicts the link expire time and makes researches on average transmission delay and weighted stability to the influence of the network stability.The route selectede by the method is obviously better than usual routing selection,it can improve the route stability,prolong the route survival time and support the most stable routing selection in the networks.
