Determining physical location of indoor objects is one of the key issues in ubiquitous computing. Although there are many
proposals to provide physical location tracking, those have some restrictions such as a dependence on the type and size of
objects and a trade-off between position accuracy and the number of sensing devices. In this paper we present a hierarchical
approach to conquer these restrictions using mobile detectors. We describe a system called MobiTra that estimates the position
of indoor any and all objects using mobile detectors’ detection histories. The effect of position estimation is evaluated
through prototype testbed and simulation.
