| Abstract: | With respect to the characteristics of industrial operation/maintenance management of substations and research on wireless sensor network time synchronization protocol, this paper presents a time synchronization algorithm combining the timing deviation compensation of the bidirectional time synchronization at aggregation nodes and the virtual bidirectional synchronization at sensor nodes.In the early stage of the network deployment,gateway nodes and aggregation nodes are arranged according to the model,and aggregation nodes and sensor nodes use different time synchronization methods.Simulation experiments show that this method has good network convergence time and synchronization precision. |
