ABSTRACT:
Communication stations select the channel which as many communication stations as possible can receive as a beacon sending channel based on interference information of each channel specified in a beacon signal. When there is a communication station which cannot receive a beacon, the beacon sending channel is changed. The communication stations can receive a beacon from all other communication stations by performing beacon receiving operation over a particular channel, avoiding the deadlock state.
