Summary:
This paper describes a method of the human-body detection by using beacon signals of a wireless LAN. To achieve stable and accurate detection, we focus on the variance of measured beacon signals over time as a signal processing technique. On the basis of evaluation in a real environment, we confirmed that the proposed scheme can achieved the detection rate of more than 90%, meaning that our scheme is effective for detecting the movement of human bodies as crime prevention measures.
