Abstract

Radio Frequency Identification (RFID) is a promising technology for automated non-line-of-sight object identification. Traditional research of RFID middleware does not concern RFID related integration with enterprise information systems. Considering the requirements of RFID middleware and business process integration with enterprise information systems, an integration framework for RFID middleware based on business process rule and data stream technologies are introduced. Main modules of the RFID integration middleware, such as devices monitoring, data management, XML business documents exchange, business process control and RFID event management, are designed and discussed in detail. The semantic definition of the complex RFID event and RFID event classification are presented. A real-time scheduling strategy of RFID event which is based on the buffer and priority queue, can process the concurrent RFID events. Application system based on RFID is realized to control the business process through RFID events.
