宽带低压电力线通讯信道冗余节点动态调度方法

A Dynamic Scheduling Method of Redundant Nodes in Broadband Low⁃voltage Power Line Communication Channel

常规冗余节点调度方法中,节点平均能耗较高,宽带网络覆盖受到限制,导致冗余节点无法被精准定位,影响节点调度效果。因此,设计了宽带低压电力线通讯信道冗余节点动态调度方法。构建电力线通讯信道模型,分析通讯信号的传输特性,定位通讯信道冗余节点,快速找到冗余节点位置,调整节点调度能耗,再建立冗余节点信息动态调度机制,确定节点能耗的动态变化,抑制宽带网络覆盖漏洞次数,进而实现宽带低压电力线通讯信道冗余节点的动态调度。利用仿真实验的方式,验证了该方法的节点能耗较低,冗余节点调度效果更佳,能够应用于实际生活中。

In conventional redundant node scheduling methods,the average energy consumption of nodes is high,and the coverage of broadband network is limited,which leads to the fact that redundant nodes can′t be accurately located,thus affecting the scheduling effect of nodes.Therefore,a dynamic scheduling method of redundant nodes in broadband low⁃voltage power line communication channel is designed.Build a power line communication channel model,analyze the transmission characteristics of communication signals,locate redundant nodes in communication channels,quickly find the redundant nodes′positions,adjust the energy consumption of node scheduling,and then establish a dynamic scheduling mechanism of redundant node information,determine the dynamic changes of node energy consumption,and suppress the coverage vulnerability times of broadband network,so as to realize the dynam⁃ic scheduling of redundant nodes in broadband low⁃voltage power line communication channels.The simulation re⁃sults show that this method has lower node energy consumption,better redundant node scheduling effect,and can be applied to real life.
