Occupancy monitoring in intelligent environment through integrated wireless localizing aggents

The application of wireless localizing agents in the occupancy detection of a single-occupant ambient intelligent environment in the presence of visitors is addressed in this paper. A wireless sensor network constructed from sensory agents of PIR motion detection sensors and door contact sensors is employed to collect the occupancy data from different areas in the ambient intelligent environment. Additionally, an RSSI detection capability is integrated to create wireless localizing agents along with tagging the occupant as a mobile node to distinguish him/her from other occupants or visitors. It is shown that by using a wireless sensor network of localizing agents for the occupancy detection of the tagged occupant, the redundancy and noise in the occupancy signal is reduced; hence, the efficiency of occupancy detection in different areas of the environment is increased.
