Smart phones have become an important part of our daily lives due to their capabilities of accessing the web using WiFi and mobile data networks. These WiFi equipment are constantly sending out packets referred as probe requests, which can be tracked using wireless sniffers. In this thesis, first we investigate capturing of WiFi probe request packets using the help of WiFi Pineapple devices, and analyze how we can use signal strength information of probe request data for indoor occupancy monitoring. Applications of such occupancy monitoring into building surveillance and building energy management are also discussed.

After completing the initial test indoors, research was moved to outdoor monitoring with the help of unmanned aerial vehicles (UAVs) flying in various trajectories and capturing probe request messages. The information captured from the probe requests is used to identify and localize WiFi users with a single UAV, which can be instrumental in search and rescue applications. Finally, we study in detail various security, privacy, and public safety issues related to drones equipped with wireless communications capabilities.
