Wireless Nerve: Invisible Anti-theft System in Wireless Sensor Network

Abstract

There are limitations in traditional anti-theft technologies. All the technologies have a common ground, that is: the devices are exposed to the space, also easily found and destroyed by adversaries. This paper demonstrates a Hidden Anti-theft System (HAS) based on wireless sensor network. The sensors can be hidden in walls and furniture. The intruder influences the transmitting link, and RSSI of the link changes. According to the changes, the system can detect the movement in monitoring area, and keep invisible. HAS is applied in indoor environment. Experiment results show that HAS achieves very low false positive and no false negative.
