Research on Time Synchronization Technology of Wireless Sensor Network

Time synchronization technology is the key support technology of wireless sensor networks. It is the core mechanism to ensure the cooperation of nodes in sensor networks. The traditional time synchronization algorithm is not suitable for wireless sensor networks. Based on the analysis of the current situation of wireless sensor network time synchronization technology at home and abroad, this paper summarizes a variety of new time synchronization protocols based on scheduling time synchronization, mixed time synchronization and distributed time synchronization. Finally, the development trend of time synchronization technology is prospected
