基于受限和洪泛的电力线载波通信组网算法

Constrained Flooding Based Power Line Carrier Communication Networking Algorithm

组网技术是低压电力线载波通信(LPLC)网络的重要基础之一。当前基于LPLC的用电信息采集系统通信所使用的组网技术主要为洪泛。但是洪泛以系统资源利用率为代价,因为缺乏有效抑制,网络中将产生大量的冗余数据并造成严重冲突。针对该问题,文章提出了一种基于受限洪泛和分级的LPLC组网算法,该机制采用限定洪泛次数及分级广播的方式以有效抑制节点间的信道冲突和通信冗余。应用分析表明,所提出的组网算法能有效地降低节点间通信冲突并提高通信效率。

The networking algorithm is one of important infrastructures of low voltage power line communication （LPLC）. The common networking technology based on the LPLC used in power consumption collection system communication is the flooding method. But the flooding method with a high system resource usage rate results in a large number of redundant data and serious conflicts because of no efficient constraints. To solve this problem, this paper propose a constrained flooding and hierarchy based LPLC networking algorithm, which limits the number of flooding and uses the hierarchy broadcast to reduce the channel conflicts and communication redundancy. Application results show that the proposed algorithm can efficiently reduce the communication conflicts among nodes and improve communication efficiency.
