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.
Aiming at the problem of unbalanced energy consumption of Low Power Lossy Network Routing Protocol (RPL), an energy-efficient RPL multi-path data flow allocation algorithm is proposed.A more realistic node energy consumption model is proposed and a new energy dispersion Degree metric to effectively determine the degree of energy balance of the nodes.A quick solution algorithm based on this metric is proposed to obtain the optimal data distribution scheme.The experimental results show that the proposed RPL multi-path data flow allocation algorithm balances the nodes Of the energy consumption, improve the reliability of routing, extend the network’s survival time.
