Initially envisioned to accelerate association of mobile devices in wireless networks,
broadcasting of Wi-Fi probe requests has opened avenues for researchers and network …

Broadcasted WiFi traffic of mobile devices is the foundation of several estimation techniques
like location tracking or crowd counting. Many pervasive applications use these techniques …

To preserve people privacy and prevent device (and people) tracking, WiFi MAC address
randomization is been introduced by an ever increasing number of operating systems …

The ubiquity of wireless devices such as smartphones, tablets and laptops, has enabled
sensing large crowds. This was made possible with numerous methods available that mostly …

In the past decade, several algorithms have been proposed to monitor people's mobility

The process of estimating the number of individuals within a defined area, commonly
referred to as people counting, is of paramount importance in the realm of safety, security …

Abstract Traditionally, Wi-Fi networks are discovered by actively transmitting probe requests.
The alternative, passive scanning, is rarely used because it is substantially slower …

In the past few years, data privacy legislation has hampered the ability of WiFi network
operators to count and map client activity for commercial and security purposes. Indeed …

Crowd density estimation is one of the critical issues in social activities. The traditional
solution to this problem is to leverage video surveillance to monitor a crowd. However, this is …

Pedestrian dynamics are nowadays commonly analyzed by leveraging Wi-Fi signals sent by
devices that people carry with them and captured by an infrastructure of Wi-Fi scanners …
