ABSTRACT:
In a self-organized distribution type wireless network without relationship between a controlling station and a controlled station, in order to execute a channel access by effectively utilizing a plurality of frequency channels, there is provided a communication system. In the system, a communication station determines a seed and generates a frequency channel switching pattern basing upon the seed. The seed is written in a beacon in each transmission frame to notify it to other stations. A new entry station scans all frequency channels, identifies a channel switching pattern of the frequency channels in accordance with the seed in the beacon received from another station, selects a candidate of a beacon transmission position and a transmission channel, and determines the beacon transmission position and transmission channel which are best for own station to transmit a beacon.
