摘要:

电力线信道的剧烈变化使得节点之间的网络连接变的很不可靠,甚至影响网络的逻辑拓扑结构。该文通过对现有电力线载波网络的路由结构进行分析比较,提出了适用于窄带低压电力载波通信的树簇路由算法,给出了树簇路由算法的协议框架,设计了簇生成算法、簇维护算法、生成树维护算法以及树维护算法的具体实现,最后给出了树簇路由策略。经过性能仿真与分析,树簇结合的动态路由适合低压窄带载波通信技术条件,满足了其工程实施的需要。

Abstract:

Physical topology of low-voltage networks is unpredictable and its Power Line Communication (PLC) channel is changeable, reliability of communication limits badly the application scale of PLC in practice. In this paper, a new Router Algorithm is proposed for PLC. Considering the channel state which is exquisite change and the successful level which is very lower in communication, dynamic clustering based on node relevance 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 relevance. In the stage of steady arithmetic, router completes the data collection through the way of fixed data transmission and gateway nodes initiating transmission. When the communication of some network nodes is unusual, the router adopts mechanism of probabilistic 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 has the flexibility, practicality and effectiveness.
