1. A communication apparatus employing a plurality of communication devices to construct a wireless network to be a control
station transmitting management information in the wireless network, the communication apparatus comprising:
a communication means transmitting information among the plurality of communication devices;
a determining means determining as to whether, when the control station disappears from the wireless network, in order that
any one of other communication devices is newly operated as a control station, the other communication devices have a control
function as a control station candidate or not;
a set means setting priority order for each of control station candidates when there exist a plurality of communication devices
to be the control station candidates; and
a notification means for notifying the wireless network of priority order information of the control station candidates, said
priority order information identifying a predetermined ordering of at least a subset of said other communication devices based
on at least one of performance and coverage information so as to avoid negotiation between said other communication devices
regarding which ultimately operates as a replacement control station,
wherein the notification means specifies, as the priority order information, stand-by times corresponding to the times until
the respective control station candidates start to reconstruct the wireless network, and
the set means sets the priority order in the order of communication quality between the control station candidate and other
communication devices for the respective control station candidates.
