Using received signal strength variation for surveillance in residential areas

Abstract

There are various uses of wireless sensor technology, ranging from medical, to environmental, to military. One possible usage is home security. A wireless sensor network could be used to detect the presence of an intruder. We have investigated the use of Received Signal Strength Indicator (RSSI) values to determine the mobility of an intruder and have found that accurate intruder detection is possible for at least short distances (up to 20 feet). The results of interference monitoring show that a wireless sensor network could be a feasible alternative for security and surveillance of homes.
