A Jini-enabled active badge system

摘要

We present an active badge system to test the efficacy of Jini as middleware for a system of small, mobile devices. Our system consists of badges that transmit infrared signals, detectors attached to fixed PC's serving as Jini clients, and a Jini server to keep track of the locations of all badges. A second type of Jini client can query the server and display location information.
