RFID Middleware Event Processing Based on CEP

As RFID is being applied in more and more business applications, events to be processed by RFID middleware is becoming more and more complex. It is needed that some original events are processed to create a complex event in order to get complex information. This paper introduced the design of an RFID middleware based on complex event process (CEP) concept, and presented checking method that is based on limited auto-machine and Hash. Moveover, a detail design of the event processing method of our RFID middleware is presented. Experiment study has also been performed with experimental results given.
