改进的AODVjr路由算法研究
首发时间:2013-11-04
摘要:针对现有的AODVjr算法在网络能量均衡方面的不足,结合节点能量和Cluster-tree算法的特点分析,提出了一种改进的AODVjr路由算法。改进算法在启动路由发现过程之前使用邻居表寻找目的节点,在路由发现过程中尽量避免低能量节点的使用,并且添加flag标志位对RREQ分组的传输范围进行控制,降低网络的总体能量消耗。仿真结果表明,改进算法能有效降低网络总体能耗,合理分担网络负载,降低死亡节点数,延长网络的生命周期。?????

The research of improved AODVjr routing algorithm
Abstract:This paper proposes an improved AODVjr routing algorithm because of the insufficiency energy equilibrium of existing AODVjr algorithm, combined with the characteristics of the Clust-tree algorithm and the node energy analysis. Improved algorithm using the neighbor table to find the destination node before start the routing discovery process, avoiding the use of low energy node as far as possible and add flag flags to control the RREQ packet transmission range in routing discovery process to reduce the network's overall energy consumption.The simulation results show that the algorithm can effectively reduce the network energy consumption and reasonable sharing network load, reduce the number of death, prolong the network life cycle.
Keywords: computer application routing algorithms AODVjr algorithm the energy equilibrium energy flag
