摘　　要：针对当前多汇聚LLN中RPL路由协议存在的雷鸣效应、待入网节点唯一决定父节点选择以及数据传输利用网络资源不够合理等问题,提出BPSM-ERPL——一种基于双向父节点选择的高效RPL改进路由协议。改进M-DAO消息使其携带数据传输速率信息,采用双向父节点选择新机制,防止大量待入网节点选择同一父节点,通过边界路由节点使数据在多个RPL实例中合理分配。理论分析和仿真实验结果表明,所提协议的网络吞吐量、数据分组传送成功率和网络生存时间优于现有相关协议。Aiming at the problem in the current research of RPL in multi-sink LLNs such as thunder effect,the nodes to be connected to the network only determine the parent node selection,and data transmission fails to make reasonable use of network resources.BPSM-ERPL,an algorithm called efficient RPL routing protocol in LLN based on bidirectional parent selection in multi-sink,was proposed.The data transmission rate information was carried by the improved M-DAO message.A bidirectional parent node selection mechanism was proposed to avoid a large number of nodes selecting same optimal parent node.The rational distribution of data among multiple RPL instances was realized through border routing nodes.Theoretical analysis and simulation results show that the presented protocol outperforms the existing algorithms according to network throughput,success rate of data packets,and network survival time.
