Abstract: A time synchronization method for wireless sensor network is provided to reduce a transform time and perform a time synchronization based on a transmission time at a reference transmitter. A time synchronization method for wireless sensor network includes the steps of: transmitting a reference packet for a time synchronization at a reference transmitter(S101), and stores the transmission time of the reference packet at the same time(S103); receiving the reference packet and storing the transmission time of the reference packet at a base station and neighboring nodes(S105); transmitting the stored receiving time of the reference packet at the base station(S107); and after receiving the receiving time of the reference packet transmitted from the base station at the neighboring nodes and the reference transmitter(S109), changing a local time corresponding to the receiving time of the reference packet(S111).
