In this paper we characterize the proprietary active scanning algorithms of several wireless network interface cards (WNICs) and driver combinations. We believe our experiments are the first of their kind to observe the complete scanning process as the WNICs probe all the channels in the 2.4GHz spectrum. We discuss the 1) channel probe order; 2) correlation of channel popularity during active scanning and access point (AP) channel deployment popularity; 3) number of probe request frames (PRFs) sent on each channel across WNICs; 4) amount of time spent on each channel across WNICs (dwell time); and 5) variation in scanning algorithms. The knowledge gained from pr...
