Reliable ALE Middleware for RFID Network Applications

Radio frequency identification (RFID), an identified object technology, utilizes air interface to deliver information required for object identification. The applicable technical information of RFID is convenient to manage and operate, and is widely promoted by the large-scale chain industry. Additionally, electronic product code (EPC) network technology enables immediate, automatic identification and sharing of information on items in the supply chain. This work presents an EPC Network backbone and an RFID service middleware with a high-reliable and highefficiency ALE-based (Application Level Event) prototype mechanism according to the EPCglobal. An SMR (Student Muster Roll) application testbed based on RFID system is implemented by the proposed ALEbased scheme. The SMR system is employed to manage the absent records of students for taking a subject, and can manage and control the operation multi-Reader devices simultaneously. The proposed system can filter attendance accurately, eliminating the possibility of reduplication in student records.
