Abstract: The present invention relates to a time synchronization method in a wireless sensor network. In the present invention, if an upper node requests a lower reference node to start time synchronization, the lower reference node broadcasts a first sync reference packet. The upper node receives the first sync reference packet and transmits the first sync reference packet reception time to the lower reference node.
