CSI-based passive intrusion detection bound estimation in indoor NLoS scenario.

ABSTRACT: Passive intrusion detection is important for many indoor safety applications. By utilizing widespread WiFi infrastructures, channel state information (CSI) based intrusion detection methods have attractive advantages such as low cost, non-line-of-sight (NLoS) support, and privacy protection. However, existing CSI-based methods lack in-depth and intensive analysis of intrusion detection bound. To the best of our knowledge, this is the first work that precisely characterizes and models CSI-based intrusion detection bound in typical indoor NLoS scenario. A bound is defined as an intruder's farthest position from the transmitter during intrusion detection. To derive a model for the bound, we first derived an intrusion-disturbed NLoS channel model by analyzing the influence of human intrusion o
