ABSTRACT
Location determination of devices in wireless networks has been around for some time. Due to the fact that most approaches are based on client collaboration, they are not suitable for being integrated in security related components as intrusion detection or access control systems. In this paper we propose an approach that works without any client collaboration and even awareness by the client. Further on, our architecture is intended to be deployed on standard state-of-the-art IEEE 802.11g access points which operate using open source firmware as OpenWRT. We use these modified access points to collect, process and relay received signal strength (RSS) values of all communicating clients. These values are then used for trilateration using a location determination algorithm on a centralized server. We also present a working prototype, its promising results and possible further enhancements of our approach.
