Reliable ALE middleware for RFID network applications

Abstract

SUMMARYRadio frequency identifi cation (RFID) technology adopts the air interface to deliver the information required for object identifi cation. 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 identifi cation and sharing of information on items in the supply chain. This work proposes an RFID service middleware with a highly reliable and effi cient 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 fi lter attendance accurately, eliminating the possibility of reduplication in student records. Performance evaluation results indicate that the proposed novel scheme is much more effi cient and reliable than a naive ALE scheme.

An efficient code gateway for RFID seamless applications

“…Therefore, the uID tag can only accommodate ID code and additional attributes of products while the remaining product information is saved in a database on the network side. Its architecture consists mainly of five elements: uIDcode, economy and entity TRON (eTRON), tags and ubiquitous communicators (UC), ubiquitous IS and uID resolution server .…”

ID-Services: an RFID middleware architecture for mobile applications

“…Finally EPCglobal has decided to leave the implementation of the middleware up to software vendors and to only specify the interface (ALE-Application Level Events) between the RFID middleware and business application. Several implementations of this specification already exist (Chen et al 2007). While the attention on RFID middleware is almost completely focused on stationary applications, it has only been regarded very little in the mobile context ).…”
