Abstract
AbstractRadio frequency identification (RFID) technology adopts the air interface to deliver the information required for object identification. The RFID system is convenient to manage and operate, and is widely encouraged by the large‐scale chain industry. Additionally, electronic product code (EPC) network technology allows immediate, automatic identification and sharing of information on items in the supply chain. This work proposes an RFID service middleware with a highly reliable and efficient application‐level event (ALE)‐based prototype mechanism according to EPCglobal. A Student Muster Roll (SMR) application test bed is implemented in the proposed ALE‐based scheme. The SMR system can be employed to manage the absentee records of students in a class, and can manage and control several operation multi‐reader devices simultaneously. The proposed scheme can filter attendance accurately, eliminating the possibility of reduplication in student records. Performance evaluation results indicate that the proposed novel scheme is much more efficient and reliable than a naive ALE scheme. Copyright © 2008 John Wiley & Sons, Ltd.
