Study on CEP-Based BCEPS Model of RFID-Based RLTLUM System

RFID technology being applied for the field of tracking and locating application faces many challenges. In order to solve the problem, we design and construct a model of RFID-based tracking and locating system which is based on complex event processing, that is BCEPS model. BCEPS model consists of physical device layer, RFID data processing layer, event processing engine, application layer and data storage layer. BCEPS model filters the RFID data which is gathered in real time and then generates RFID events. At the same time, BCEPS model responses to the requirement coming from users and then generates user events. RFID and user events are sent to event processing engine and are processed. Finally, results are returned to users. To enhance the efficiency of processing massive events and the real-time performance of system, we first propose and design the real-time event scheduling algorithm for event processing engine. Finally, we verify BCEPS model by implementing RFID-based tracking and locating system in underground mine which uses the time-shifting tracking and locating algorithm which is designed by ourselves.
