User presence detection based on tracking network activity in smartroom

The SmartRoom system provides a set of services for assisting collaborative activity when many participants are physically present in the same room. The SmartRoom service intelligence is due to the use of diverse sources of information on ongoing activity. One promising source is information on user presence and network activity of the participants. In this paper, we consider the problem of utilizing such an information source for smart spaces based on the Smart-M3 platform. We employ the Innorange technology, which is one of the many examples for passive radio detection in WLAN. We define scenarios with this information source for use in SmartRoom services. We propose an integration solution oriented to Smart- M3 applications. Our software prototype is integrated into the SmartRoom system. Experimental study confirms the feasibility and reasonable performance of the proposed solution.
