摘　　要：针对现有BPLC网络组网协议在回复关联确认消息的数量和时间上存在冗余的问题,对BPLC报文交互过程进行研究,提出一种基于自适应组播的高效组网协议。通过自适应地聚合关联确认消息并采用组播方式发送,在减少控制开销的同时加速发送部分关联确认消息。理论分析显示了该协议的有效性。仿真结果表明,与现有BPLC网络组网协议相比,该协议能够减少5.88%以上的控制开销并降低5.53%以上的入网时延。Aiming at the redundancy problem of the existing BPLC network networking protocol in terms of the number and time of replying association confirmation messages,the BPLC message interaction process was studied,and an efficient networking protocol based on adaptive multicast was proposed.By adaptively aggregating association confirmation messages and sending them in a multicast manner,the transmission of partial association confirmation messages was accelerated while reducing control overhead.Theoretical analysis shows the effectiveness of the new agreement.The simulation results show that compared with the existing BPLC network networking protocol,the proposed protocol can reduce the control overhead by more than 5.88%and reduce the network access delay by more than 5.53%.
