%0 Thesis %1 vesti2006 %A Vesti, Jens %D 2006 %K fingerprinting network positioning surveillance wireless %T Indoor Intruder Positioning in a Multimodal Wireless Network %U http://www.itu.dk/people/vesti/thesis.pdf %X Traditional positioning systems based on wireless networking technologies, requires a user to carry a mobile station which is then being positioned. It is not likely that an intruder carries a mobile station, and it would therefore be impossible to estimate his or her position using traditional positioning systems. But using the fact that an intruder cannot avoid affecting the signal propagation environment, we can detect the changes using the wireless access points, deployed in the building, during a continuous transmission between each of the access points. In this thesis, we present a concept, and a system for estimating the position of an intruder, without the use of a mobile station. We carry out a series of tests in different environments, under different conditions, with components off the shelf in the form of wireless access points. A model is presented that explains why, and how, the signal propagation environment is affected by the presence of an intruder, in the area being monitored. Finally we conclude that estimating a position of an intruder, without a mobile station, is possible, though quite imprecise. With the knowledge obtained and presented, a solid foundation for further research is laid and higher precision can be reached in future experiments.
