We have already developed embedded software in off-the-shelf WLAN APs, our system can sniff out data packets transmitted by WLAN devices without the need to install client programs on mobile user devices. Experiment results show that once wireless activities had been detected, our signal strength based localization algorithm can estimate positions of the(More)
With the prevalence of mobile Wi-Fi devices and infrastructures, there are growing interests in mobile surveillance and device tracking for providing better location-aware services in metropolitan areas. With a good location estimation integrated into a wireless infrastructure, system administrators can closely monitor the network traffic as well as the(More)
With the prevalence of Wi-Fi activity within a wireless network, there are growing interests in mobile surveillance and device tracking for better network services. With a good location estimation algorithm integrated into a wireless network, system administrators can closely monitor the network traffic as well as the behavior of the mobile users. By(More)
With a good location estimation integrated into a Wi-Fi surveillance system, system administrator can closely monitor the network traffic as well as the behavior of the mobile users. Hence, there is a growing demand to have a quick and efficient way to indentify a specific group of people, or devices or asset within a controlled wireless network. In our(More)
