A communication system has stations arranged in clusters of member stations, each of which communicates with the other member stations. One member station is a head station of the cluster that communicates with head stations of other clusters. The stations are configured by determining the communication state between a station and one or more cluster head stations. The station is assigned to at least one cluster when a prescribed communication state has been determined between the station and the cluster head station. The station is set to be in independent communication with the one or more cluster head stations which have the prescribed communication state with the station.
