An Empirical Analysis of Wi-Fi Activity in Three Urban Scenarios
A better understanding of people's daily behaviors with respect to the underlying wireless network is a crucial step toward Wi-Fi based pervasive networking. Existing analyses found in the literature have focused on closed environments such as university campuses, offices, or conferences. This paper develops a new approach to analyze Wi-Fi user behaviors in the wild based on wireless sniffing. With the technique, the authors are able to investigate Wi-Fi activity in areas usually inaccessible to traditional systems. Moreover, instead of focusing on a single network, the authors capture behaviors of all users around specific locations regardless of their relationship with existing networks.
