The present invention relates to a method of controlling broadcasting in a wireless sensor network. The method includes performing broadcasting from an upper node to a lower node for a predetermined number of times, transmitting a time offset calculated according to the broadcasting from the lower node to the upper node, calculating an average of the time offsets received from at least one lower node, by the upper node and resetting the number of times of broadcasting according to the calculated average by the upper node. Accordingly, the number of times of broadcasting may be controlled according to the average of received time offsets in the wireless sensor network. In another aspect, an adjustment to the number of times of broadcasting may be received and the number of times of broadcasting may be adjusted based on an average of the received adjustments.
