WiFi clients and access points (APs) in large-scale and dense WiFi networks transmit millions of MAC layer frames at a granularity of microseconds. Thus, resulting in performance problems due to complex MAC layer interactions that may not be useful. Literature suggests existence of three such problems-(1) Useless and Aggressive Active Scanning (AAS), (2)(More)
—IEEE 802.11 WLAN (Wireless or WiFi LAN) clients discover neighboring APs (Access Points) by active or passive scanning. Such an active scan of WLAN injects probe frames in the network. Network conditions like packet losses, roaming, etc. result in increased active scanning and hence, an excessive increase of the probe traffic. Of the several causes(More)
