摘要： 针对ZigBee网络中AODVjr路由算法存在节点死亡率高、网络能耗大的问题,结合节点的存储结构、能量和链路质量特点,提出一种改进的ZigBee网状网络路由算法F-AODVjr。在路由发现之前,利用路由节点自动维护的邻居表寻找目的节点,以降低因路由请求(RREQ)分组寻址目的节点导致的能量消耗。在路由发现阶段,通过改进AODVjr路由算法的最短路径寻址思想,设计含有路由跳数、节点剩余能量和链路质量的路由算法,寻找具有最低路由成本的优化路径。仿真结果表明,F-AODVjr路由算法可以有效降低网络整体能量消耗,提高节点生存率及数据分组成功投递率。

Abstract: In ZigBee network,aiming at the problem that AODVjr routing algorithm has a high node mortality and large energy consumption,combined with the storage structure,the energy and link quality characteristics of the node,an improved F-AODVjr routing algorithm is proposed.The Improved algorithm uses neighbor list maintained by routing node to find destination node before starting a route discovery process,in order to reduce the energy consumption of starting a process in Route Request(RREQ) addressing destination node.In the routing path discovery phase,routing algorithm is designed with routing hop,residual energy and link quality to find the optimal path with minimum routing cost,and the thought of shortest path in AODVjr routing algorithm is improved.Simulation results show that the F-AODVjr routing algorithm effectively reduces the network energy consumption,raises node’s survival rate and packet’s successful delivery rate.
