Abstract
A packet collision among a plurality of access points is avoided and QoS is ensured. An access point that shares a wireless channel with a plurality of access points to carry out communication is provided with a function for determining, based on information contained in a polling communication signal or a broadcast signal transmitted from another access point, an access point (preceding AP) that is to perform polling communication immediately before the own station to form a group within which the order of the polling communication is determined, and after determining that a polling communication period of the preceding AP has ended, starting the polling communication period of the own station in a wireless network.
