Abstract

WSN is a typical distributed system. Data fusion, energy management, transmission scheduling, target tracking and positioning, and network security all require monitoring nodes in the wireless sensor network to maintain time synchronization. The application of synchronization technology at this stage is discussed. The clock model of the nodes in WSN is given, and the basic types of time synchronization technology are introduced respectively: RR mechanism, SR mechanism, RO mechanism, and hybrid synchronization mechanism. The principle of synchronization mechanism of different time synchronization algorithms in each mode is analyzed. The application scope, advantages and disadvantages are analyzed. The error analysis is simulated, the requirement of wireless sensor network for time synchronization is analyzed, and the existing time synchronization technology is compared. Finally, the HRTS algorithm is selected as the synchronization mode of the WSN network.
