A communications system for communication among plural stations in a network has stations (CH1, CM2, CM3, CH4, CH5, CM6, CM7) arranged in clusters (1a, 1b, 1c) of communication member stations, each communicating with each other. One of the member stations (CH1, CH4, CH5) is a head station of the cl
A communications system for communication among plural stations in a network has stations (CH1, CM2, CM3, CH4, CH5, CM6, CM7) arranged in clusters (1a, 1b, 1c) of communication member stations, each communicating with each other. One of the member stations (CH1, CH4, CH5) is a head station of the cluster. The cluster head stations (CH1, CH4, CH5) communicate with other cluster head stations (CH1, CH4, CH5). A method for configuring the network of stations includes a step of operating at least a first (CH5) and a second (CH4) station of the plural stations as cluster head stations, the first (CH5) and second (CH4) stations forming a communications link. The method also includes a step to resign the first (CH5) station from operating as a cluster head station when a predetermined resignation condition is met. The method also includes a step of maintaining the communication link between the first (CH5) and second (CH4) station as the first station (CH5) transitions from operating as a cluster head station (CH5) to operating as a cluster member station (CM5) of a cluster headed by the second cluster head station (CH4).

1. A mobile communications station which communicates among a plurality of mobile stations in a network in which stations are arranged in clusters of communication member stations, with one member station in each cluster being a head station for the cluster, each member station communicating with the network through one or more cluster head stations, the cluster head stations communicating with other cluster head stations, the mobile station including a transceiver which transmits signals to and receives signals from mobile stations in the network, said mobile communications station comprising:a memory having network information stored thereon; a processor which (i) operates said mobile station as a cluster head station; (ii) resigns said mobile station form operating as a cluster head station; and (iii) maintains affiliation with a cluster head neighbor at least during a period in which said mobile station resigns from operating as a cluster head station and commences operating as a cluster member of the cluster head neighbor, wherein sad processor determines whether said mobile station is a network n-connectivity point, and prevents said mobile station from resigning as a cluster head station when said mobile station is an n-connectivity point, wherein said processor selects a first neighboring cluster head station to maintain affiliation with while resigning as a cluster head station, and wherein said processor controls the transceiver to transmit a signal to the selected first cluster head station requesting a status change from a cluster head station to a cluster member station.
