摘　　要：针对有损低功耗网络(Low-power and Lossy Network,LLN)中由于无线链路的有损特性以及节点部署不均匀无法有效实现网络能量均衡,提出一种基于能量均衡的高效低时延路由算法(Efficient Low Latency Routing Algorithm Based on Energy Balance in Low-Power and Lossy Networks,ELLEB-RPL)。该算法采用"ELLEB组网"策略,使得节点能够有效避免在DODAG(Destination Oriented Directed Acyclic Graph)间来回切换;通过采用"最优父节点选择"策略,使得节点选择的父节点达到最优;通过采用"流量自适应分配"策略,达到网络能量均衡的目的。仿真结果表明,ELLEBRPL在Sink节点平均吞吐量、网络平均寿命以及端到端时延上均有提升。In the low-power and lossy network(LLN),network energy balance cannot be effectively realized due to the lossy characteristics of the wireless link and uneven node deployment. For this problem,an efficient low latency routing algorithm based on energy balance(ELLEB-RPL) is proposed. The algorithm adopts the "ELLEB networking" strategy so that nodes can effectively avoid frequent switching between DODAGs. By adopting the "optimal parent node selection" strategy,the parent node selected by the node can reach the optimal value. By adopting the strategy of "traffic adaptive allocation",the goal of network energy balance can be achieved. The simulation results show that ELLEB-RPL improves the average throughput of Sink node,the average lifetime of network and the average end-to-end delay.
