摘要
针对低功耗有损网络路由协议(RPL)能耗不均衡问题,提出一种能量有效的RPL多路径数据流分配算法.建立了一种更加符合实际的节点能量消耗模型,提出一种能量离散程度度量标准,以有效判定节点的能量均衡程度.基于该度量,提出一种快速求解算法,以获得数据的最优分发方案.实验结果表明,所提出的RPL多路径数据流分配算法均衡了节点的能量消耗,提高了路由的可靠性,延长了网络的生存时间.
An energy-efficient multi-path routing protocol for low-power and lossy networks（ RPL） distribution mechanism,energy-efficient routing protocol for low-power and lossy networks（ EM-RPL）,was proposed to solve the problem on imbalance of power consumption in RPL. Firstly,a model of node energy consumption was established,which is more in line with the actual node energy consumption. Secondly,an energy dispersion degree measurement criterion was presented. Based on this measure,a fast algorithm was proposed to obtain the optimal distribution of the data. Simulation results show that the improved RPL algorithm can balance the energy consumption of nodes,improve the reliability of routing,and prolong the lifetime of the network.
