Leveraging neighbors' wireless access points in wireless-signal-variation-based physical intruder detection systems

摘要

A method for intruder detection is provided. The method includes monitoring, at a wireless sniffer in a building, received signal strength relative to each of a plurality of wireless access points, wherein a first wireless access point of the plurality of wireless access points is located within the building and a second wireless access point of the plurality of wireless access points is located external to the building. The method includes creating a profile of the received signal strength from each of the plurality of wireless access points, during a learn mode and comparing activity of the received signal strength from each of the plurality of wireless access points to the profile, during an intruder detection mode. The method includes issuing a notification, based on the comparing. An intruder detection system is also provided.
