Disclosed is a method and system for switching at least one wireless node located within the coverage area of a basic-service set (BSS) or infrastructure-basic-service set (IBSS) in a wireless-local-area network (WLAN) from a first communication channel to a second communication channel. The method includes: determining whether the second communication channel to be used by at least one wireless node is needed; broadcasting by a source node a management frame to at least one of the wireless node when it is determined that the second communication channel is needed, the management frame including a channel-switch time and a second communication channel identifier; and switching, at least one wireless node receiving the management frame, from the first communication channel to a second communication channel within a countdown time corresponding to the channel switch time, wherein the channel-switch time is less than a beacon interval.
