REMOVAL OF AMBIGUITIES IN FORMING NEW PICONET CONTROLLER (PNC) WHEN CURRENT PCN SUDDENLY BECOMES UNAVAILABLE

PROBLEM TO BE SOLVED: To provide a method of removing ambiguities in forming new piconet controller (PNC) when the current PCN suddenly becomes unavailable.SOLUTION: A piconet in which at least one master communication station and at least one slave communication station are self-designated implements a successor hierarchy. A wireless device (DEV) functioning as a piconet controller polls a plurality of DEVs to obtain data concerning other DEVs in range of each polled DEV. The data concerning other DEVs in range of each polled DEV is received, and at least one successor DEV is selected as a successor PNC on the basis of the received data concerning stations in range of each polled DEV. The selection of the successor DEVs is communicated to the successor DEVs. This provides continuity of communication.
