Enhanced active scanning in wireless local area networks
Abstract
A method for active scanning in a wireless network may include two transmitters. In such a method, the following steps may take place: initiating active scanning on at least one of a plurality of channels; waiting to transmit a first probe request on a first channel of the plurality of channels based on a delay timer; receiving at the first STA, while the delay timer is not expired, a probe request from a second STA; and skipping the first probe request on the first channel of the plurality of channels based on information contained in the received probe request from the second STA.
