摘　　要：针对现有低压宽带电力线通信网络拓扑不均衡问题,提出一种宽带电力线通信网络最优中继选择算法。从入网申请节点到中央控制器所有路径中选择信噪比最高的路径,使节点选择最合理的中继节点;利用信标报文丢包率记录节点间通信状态,使节点分布更加均衡;以公有中继节点为顶端节点建立倒V型中转策略,提高数据传输效率。实验结果表明,该算法在平均端对端时延、网络控制开销、数据传输成功率等性能上优于现有技术。Aiming at the unbalanced topology of the existing low-voltage broadband power line communication network,an optimal relay selection algorithm for broadband power line communication network was proposed.The path with the highest signal-to-noise ratio among all paths was selected from the network application node to the central controller,so that the node selected the most reasonable relay node.The beacon packet loss rate was used to record the communication status between nodes to make the node distribution more balanced.An inverted-V transfer strategy was established with the public relay node as the top node to improve the data transmission efficiency.Results of simulation show that the algorithm is superior to the existing technology in terms of average end-to-end delay,network control overhead,and data transmission success rate.
