RFID middleware design: addressing application requirements and RFID constraints

Radio Frequency Identification (RFID) technology holds the promise to automatically and inexpensively track items as they move through the supply chain. The proliferation of RFID tags and readers will require dedicated middleware solutions that manage readers and process the vast amount of captured data. In this paper we analyze the requirements and propose a design for such an RFID middleware. We argue that an RFID middleware should not only focus on the application needs, but must also consider the constraints imposed by passive RFID technology.
