PURPOSE: A super frame structure for mesh networking and beacon scheduling method is provided to easily adapt to the conversion of a network environment by executing a beacon scheduling in a distribution method. CONSTITUTION: A join node acquires the neighbor node beacon allocation information of the neighbor node from the beacon of the received neighbor node(S203). The join node selects an empty beacon slot(S205). A node selected by a beacon slot periodically transmits beacon to the corresponding beacon slot(S211). When the beacon is not received from the neighbor node, the joint node forms a network(S207). The joint node selects the beacon slot of a first super frame within space between beacons(S209).
