ABSTRACT:
The coordinator broadcasts a candidate inquiry request command while having a list of candidate coordinators performing a coordinator role. The candidate coordinators receive the candidate inquiry request command, one of the candidate coordinators broadcasts a candidate notifying command, and other candidate coordinators check whether the candidate notifying command has been received. Devices check whether the candidate notifying command has been received from the candidate coordinator, and broadcast a candidate inquiry information command including the candidate notifying command receipt information. The candidate coordinator checks whether the candidate inquiry information command has been received, and broadcasts a candidate inquiry response command including number of accessible devices and the candidate notifying command receipt information. The coordinator receives the candidate inquiry response command and estimates communication performance ranks for the respective candidate coordinators.
