摘要：

Exact time synchronization is one of the main conditions for realizing wireless sensor network's self protocol run, data fusion, TDMA attempter, cooperative sleep, orientation etc. The architecture of wireless sensor network (WSN) for large generator on-line monitoring is analyzed firstly. Then a time synchronization scheme which is suitable for the wireless sensor network is proposed on the basis of comparing existing time synchronization protocol, mechanism and algorithm of wireless sensor network. This time synchronization scheme integrates internal synchronization with external synchronization, unidirectional broadcast combined with linear regression is adopted in the course of synchronization. At last the algorithm is simulated and compared by simulation software NS, which proves that the algorithm is suitable for the monitoring networks.
