Research by Dr. Moustafa Youssef

Today I had the opportunity to attend a session given by Dr. Moustafa Youssef on his research. The key point in his talk was about detecting the presence of humans inside a wireless network area by detecting variations in the wireless signal strength (Received Signal Strength Indicator, RSSI) at the receiver side. Dr. Moustafa introduced his Horus system based on this concept! Imagine the scenario in which your home wireless network acts as an intrusion detection system while you are sleeping at night. Dr. Moustafa and his group developed an all-software solution that provides this functionality by utilizing the hardware of the deployed wireless network and your laptop! If you are really interested, you can watch his Google Tech Talk here. The same concept is eventually being applied in hospital settings as well as discussed in this paper.
