A method of generating networks by utilizing a multi-channel so that channels may be efficiently used, inter-channel interference may be avoided, and a network may be energy efficiently managed is provided. Through a super personal area network (PAN) coordinator that manages all networks based on a multi-channel, a PAN capable of avoiding inter-channel interference may be formed. In addition, it is possible to grasp use states of channels used for transmitting and receiving beacon frames, to observe a change in a network topology, and to form an energy efficient PAN.
