摘　　要：针对窄带电力线网络节点通信状态变化剧烈和通信成功率低的问题,提出了一种新的基于节点相关度的动态网络分簇算法。该算法根据接收信号强度、历史抄通概率和网络连通度选取簇头节点,根据节点相关度确定簇内成员;在算法稳定工作阶段,路由以固定数据传输和网关节点主动发起传输相结合的方式来完成数据收集;当部分网络节点以现有路径不能正常通信时采取基于邻居节点数目的概率泛洪机制重构网络,可保证数据的即时传输。分析表明该路由器具有灵活性、实用性和有效性。As the node state of power line communication network changes exquisitely and its success rate is very low,a dynamic clustering algorithm based on the node relevance is proposed,which selects cluster head according to the signal intension,historic communication probability and node connectivity rate,and determines the cluster members based on node relevance. Within the steady working stage,the router completes the data collection by the fixed data transmission and the gateway initiating transmission. When some nodes could not communicate properly via existing paths,the probabilistic flooding mechanism based on the number of neighboring nodes is used to rebuild network for ensuring the real-time data transmission. Analysis shows that this router has better flexibility, practicality and effectiveness.
