【Abstract】 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.更多还原
