一种新的低压电力线载波网络软件路由器设计

Design of a New Software Router for Low-Voltage Power Line Carrier Networks

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软件路由器的设计方法。该路由器根据接收信号强度、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;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。分析表明这种路由器具有灵活性、实用性和有效性。

In this paper, design of a new software routing is proposed for power line communication. With regard to the great changes in channel state as well as the small ratio of successful communication, dynamic clustering based on correlation of node is used. According to the intension of signal, the probability of communication and connectivity of node, the router selects cluster head and the members of cluster based on Node correlation. When the communication of some network nodes is unusual, the router adopts mechanism of probabilisfic flooding based on the number of nearby nodes to rebuild network. This method can guarantee real-time data transmission. The analysis shows that this router is flexible, practical and effective.
