Abstract
A communications system for communication among plural stations in a network has stations (CH CM CM CH CH CM CM ) arranged in clusters ( ) of communication member stations, each communicating with each other. One of the member stations (CH CH CH ) is a head station of the cluster. The cluster head stations (CH CH CH ) communicate with other cluster head stations (CH CH CH ). A method for configuring the network of stations includes a step of operating at least a first (CH ) and a second (CH ) station of the plural stations as cluster head stations, the first (CH ) and second (CH ) stations forming a communications link. The method also includes a step to resign the first (CH ) 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 (CH ) and second (CH ) station as the first station (CH ) transitions from operating as a cluster head station (CH ) to operating as a cluster member station (CM ) of a cluster headed by the second cluster head station (CH ).
