在设计基于电力线载波通信的智能家居系统时,为应对电力线信道的时变性和随机性特征而提出了一套基于遗传算法思想的动态路由算法,以实时寻找传输路径,调度载波信号在各个节点间的传输。采用此算法可成功实现某个组控与其下属终端之间以及总控和各组控之间的通信。本算法中,除控制器节点外的其它节点都采用相同的驱动程序,因而实现了节点的即插即用。
In designing smart home system based on power line carrier communication, a set of dynamic routing algorithm based on genetic algorithm is proposed to deal with the time-varying and random characteristics of power line channel. In order to find the transmission path in real time and schedule the carrier signal between nodes The transmission. Adopting this algorithm can successfully achieve the communication between a group control and its subordinate terminals and between the general control and each group control. In this algorithm, the same drivers are used for all the nodes except the controller node, thus realizing the plug-and-play of the nodes.
