针对Ad hoc多径路由网络中各路径相互干扰的问题,提出了一种基于节点相关因子模型的多路径路由算法(AOMDV-LR)。该算法利用中间节点能够监听邻近节点接收报文的特性,结合邻近节点路由请求包数量的信息来计算每个中间节点的相关因子,得到总相关因子最小的节点不相交路径,保证各路径的数据传输干扰程度为最低。仿真结果表明,AOMDV-LR算法能显著增加数据包的投递率,降低端到端的传输时延。
The paper presents a new multi-path routing algorithm (AOMDV-LR) based on the model of node correlation factors to solve the problem of paths' interference in Ad hoe multi-path routing network. This algorithm uses the character that intermediate nodes have the ability of monitoring adjacent nodes' information of receiving packets, and combines the packets' amount of the request from adjacent nodes routing to calculate the correlation factor of each intermediate node. The aim of this algorithm is to get the minimum disjoint path of the sum of correlation factors to ensure the interference degree of .the paths' data transmission is the lowest. Simulation results show the proposed algorithm can improve the packet delivery rate uncommonly, and reduce the end to end transmission delay.
