Abstract
WLANs are indispensable for providing Internet access to users at locations such as universities, corporate offices, conferences, airports, and coffee shops. Many of these environments often experience flash crowds, which we define to be a sudden surge in the number of users simultaneously attempting to access the WLAN. When flash crowds occur, WLANs are likely to suffer from destructive interference, excessive channel load, and unsustainable packet processing at access points (APs). These conditions lead to a plethora of problems, such as a deterioration in network throughput, heavy packet loss, intermittent connectivity, overwhelmed APs, and sometimes, a network collapse. To verify these claims, we present two case studies of operational WLANs that experienced the aforementioned problems. The two WLANs each consisted of over 100 APs and more than 1000 simultaneous users, deployed at recently held 62 nd and 64 th Internet
