摘　　要：针对当前低功耗有损网络拓扑构建及路径选择的参考度量单一,能量均衡性差的问题,提出了一种基于三角模算子的RPL协议路由优化算法。本文阐述了低功耗有损网络路由协议的网络拓扑构建机理和路由过程,基于三角模融合算法,重新定义了网络节点的能量指标和逻辑距离隶属度并进行了融合,更为合理地进行父节点选定,实现数据采集传输业务可靠性和有效性的进一步提升,最后通过实验仿真验证了改进后的路由协议性能。For the current routing process and topology construction of low-power and lossy networks（LLNs）goingwith unique factors and unbalance energy distribution,an improved routing algorithm for RPL protocol based on tri-angle module operator is proposed to optimize path selection. This paper describes the mechanism of network topolo-gy and routing process of Routing Protocol for LLNs（RPL）,also proposes a new index fusing the energy and logicaldistance of the nodes through triangle module operator. As a result,more reasonable parent node selection isachieved and further improvement of the reliability and effectiveness of data acquisition and transmission is real-ized. Finally,the performance of the optimized routing protocol is verified through simulation experiments.
