ABSTRACT:
A communications system has stations arranged in clusters (1a,1band1c) of communication member stations (CM2, CM3, CM6and CM7), with one member station (CH1, CH4or CH5) in each cluster being a head station for the cluster. Each member station (CM2, CM3, CM6and CM7) communicates with the network through a cluster head station (CH1, CH4or CH5). The cluster head stations (CH1, CH4and CH5) communicate among other cluster head stations (CH1, CH4and CH5). A mobile communications station (e.g., CM3) evaluates a beacon message received from a first member station (e.g., CM6) of the plurality of mobile stations through a transceiver6. The station CM3also determines whether to communicate with the first member station CM6directly or to communicate with the first member station CM6by forwarding messages through a cluster head station CH1that is affiliated to the mobile communications station CM3.
