摘要
提出了一种可靠的节点不相交多路径路由算法(RNDMRA).结合预测模型和能量模型,利用网格中节点的地理信息,有效减少路由发现泛洪的频率.同时为了选择与最短路径相似的稳定多路由,RNDMRA应用相似性因子选择相似的稳定节点不相交多路径路由.模拟结果显示,与AODV和NDMR相比,RNDMRA有更高的投递率,更小的路由延迟和路由负载.
A new scheme called reliable node-disjoint multipath routing algorithm （RNDMRA） is presented. Based on prediction model and energy model, RNDMRA utilizes node＇s geographical information and effectively reduces the frequency of route discoveries. And in order to select stable multiple routes similar with the shortest path, RNDMRA uses similarity fact-or to select similar stable node-disjoint multipath routes. Simulation results showed that, compared with AODV and NDMR, RNDMRA has a higher packet delivery ratio, lower route delay and routing load.
