Other AbstractThis utility model claims a wireless sensor network time synchronization method comprises: Creation of layer of wireless sensor network; According to the upper layer node to the lower layer node sends message sending time and the lower layer node in the local of the received message the receiving time of calculating clock state parameter estimation value; Calculating clock state transferring coefficient according to the computer the clock state parameter estimated value computing coefficient observation; According to last time clock state and clock state transfer coefficient prediction current clock state and according to clock state parameter estimation value and the test data to the predicted current clock state updating; According to updating of the current clock state and the lower layer node upper layer node to do time synchronization. The invention it realizes the hierarchical wireless sensor network high precision time synchronous.
