Real-Time Data Stream Management System for Large Volume of RFID Events

A data stream management system (DSMS) for the real-time processing of a large volume of RFID events is proposed herein. It allows the real-time scheduling of groups of operators, the components of a query, to process user queries of various kinds within the time limit. It also creates user-level threads consisting of operators, and the DSMS scheduler schedules the threads of a query, depending on the priority. A prototype of the proposed system was built, and the scheduling of a large volume of RFID events was shown through experiments.
