SYSTEM AND METHOD FOR PERFORMING BUILDING-WIDE WIRELESS NETWORK INTRUSION DETECTION VIA CONNECTED LUMINAIRES

摘要

A method (100) and connected lighting system (10) for detecting an intruder to a wireless network (24) of a connected lighting system formed by a plurality of luminaires (14). Each luminaire receives (120), over a designated time interval, a physical layer characteristic of each client device (26) accessing the wireless network. An array (50) of reference distributions is retrieved (110) by a processor of the system. Each reference distribution corresponds to an expected distribution of the characteristics for one of the luminaires during a corresponding time interval. An observed distribution is generated (130) for each luminaire, representing an actual distribution of values of the characteristic received by one of the luminaires over the designated time interval. Each observed distribution is compared (140) to the appropriate reference distribution for the designated interval in order to detect an anomaly and initiate an alarm status.
