摘　　要：针对Zigbee网状网络AODVjr路由算法在路由发现过程中引起的节点能耗不均衡问题,提出了一种通过有效选择转发节点,动态建立通信路径的路由选择算法。该算法在定义通信代价函数的基础上,通过限定邻居前区集合来确定待选节点集,并综合考虑待选节点的剩余能量以及待选节点转发数据至下一跳的能量损耗,选择具有最小通信代价的节点转发数据,尽可能的减小节点在路由发现过程中所引起的不必要的能量损耗。仿真结果表明,该算法能够有效地均衡节点能量、降低网络能耗、延长网络生命周期。Aimed at the problems that unbalanced node energy consumption in the process of routing discovery in Zigbee AODVjr routing algorithm, a routing algorithm which can effectively select the forward node and dynamically establish communication paths is proposed. In the basis of communication cost, through the former area of neighbors to determine the conditions of matching nodes, comprehensive consideration of the residual energy of candidate nodes, the energy consumption of candidate nodes forward data to the next hop, the minimum communication cost of node is choosen to forward data and to reduce the unnecessary loss of energy in the process of route discovery. The simulation results indicate that the algorithm can effectively balance node energy, reduce network energy consumption, extend the network＇s lifetime.
