Transfer-type clock calibration and synchronous dormancy method of wireless sensor network

The invention discloses a transmission type clock calibration and synchronous dormancy method of a wireless sensor network. The method is used in a wireless sensor network system which has large-scale child node layout and has high requirements on dormancy management and clock precision. According to the method, clock calibration is carried out on all nodes in a network by utilizing a transmission mechanism of a data link in the network, the calibration method takes a sink node as a 0 # calibration source, and the network transmits a clock calibration signal downwards step by step from the sink node by virtue of a message transmission path; the clock calibration data frame is written by the sink node or rewritten by the forwarding node which completes clock calibration, and the transmission-type diffusion of the clock calibration is realized in this way. The method is not affected by network depth, channel resources are saved, dormancy clock information is transmitted step by step from a sink node to a termin
