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 continuous development of wireless MESH network technology, the client-based MESH network, node movement caused by the network topology changes affect the routing. Therefore, considering the movement of network nodes, how to choose a stable route is a problem that must be faced. Aiming at this problem, a method of stability routing based on motion prediction is proposed. The method predicts the link lifetime and at the same time studies the influence of average transfer delay and weighted stability on the network stability. The proposed method is obviously superior to the traditional routing, which can improve the path stability, extend the path survival time and achieve stable routing.
