摘　　要：为解决Ad-Hoc路由协议查找路径过程中,由于从源节点到目的节点的传输路径会因为某个节点移动而导致整条路径中断,造成最短路径通常不是最稳定路径问题,提出一个以信号方差为基础的路由选择方法。通过侦测到的节点间信号强度,观察其信号变动程度,当信号变动值很小时,表示该节点间的链接处于稳定的状态,较不易断线。这些稳定链接组成的路径将是一条最稳定的路径。通过实验仿真验证,利用该方法所选路由,路径的稳定度明显优于其它算法。To solve the problem that the shortest path is usually not the most stable path because the transmission path from the source node to the destination node will be interrupted due to the movement of a certain node during the path search process of the Ad-Hoc routing protocol,a routing method based on signal variance was proposed.The degree of signal variation was observed through the detected signal strength between nodes.When the signal variation value was small,it meant that the link between the nodes was in a stable state and was less likely to be disconnected.The path composed of these stable links would be one of the most stable paths.Through the experimental simulation verification,using the route selected using this method,the stability of the path is obviously better than that of other algorithms.
