Continuous location tracking in an assistive environment is considered to be the fundamental step for most of the monitoring applications, as it provides a very good indication about different ongoing activities. But, tracking in a multi-person environment, such as hospitals, requires simultaneous identification and localization mechanisms, which makes the system extremely complex. In this paper, we describe a system that uses RFID and other passive sensors deployed at various locations of the environment to continuously track and identify a person in a multi-person assistive environment. Given, sensor activations at different time points, the proposed system considers location uncertainties of each person and applies the nearest neighbor algorithm to update the location of a person.
