摘　　要：为了满足低压电力线网络的自适应性、时效性需求,在分析了电力线网络信道特点及拓扑结构后,指出了侦听一个时间片循环以优选最短路径的思路,提出了一套基于时分复用信道接入机制的自适应组网算法,给出了算法网络层协议及对应状态机,并使用Matlab建立了一系列仿真模拟机制及节点模型,以仿真电力线网络上实时数据流信息和组网结果。仿真结果表明,相比近年来的分簇算法,该算法在组网时间、平均通信长度和平均通信跳数方面都有明显优化,能在组网时效性和网络性能方面取得平衡。In order to fulfill the demands of self- adaptivity and timeliness of the low- voltage power line network,the thought of optimizing the shortest route by monitoring the network for one cycling period is pointed out by analyzing the channel characteristics and topology structure of the power line network. A set self-adaptive networking algorithm based on time division multiplexing channel access is proposed,and its network layer protocol and corresponding state machine are given. In order to simulate the real-time data flow information and networking results of the power line network,a series analogue simulation mechanisms and node models were set up with Matlab. The simulation results show that,in comparison with the clustering algorithms in recent years,the proposed algorithm can optimize the networking time,average communication length and average communication hop obviously,and achieve a good balance between networking timeliness and network performance.
