Nuzzer: A Large-Scale Device-Free Passive Localization System for Wireless Environments

The widespread usage of WLANs and mobile devices has fostered the interest in localization systems for wireless environments. The majority of research in the context of wireless-based localization systems has focused on device-based active localization, in which a device is attached to tracked entities. Recently, Device-free Passive localization (DfP) has been proposed where the tracked entity is neither required to carry devices nor participate actively in the localization process. Previous studies have focused on small areas and/or controlled environments. In this paper, the authors present the design, implementation and analysis of Nuzzer, a large-scale DfP localization system, which tracks entities in real environments, rich in multipath.
