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.

Technological advances and pervasiveness of the Internet have recently led to the development of diverse technologies for the digital home. This study presents an RFID-based interdynamic system with an OSGi platform to support applications for digital home surveillance. In the proposed system, the OSGi platform is called a Residential Gateway, and it controls and manages the digital home services. Four service functions, called bundles, are designed to support the home interdynamic application. These bundles are the Device Access, the RFID Device Manager, the Monitoring and the RTP Receiver bundles. The proposed system is applied in the interdynamic between people and home appliances. A person holding RFID Tags is identified by the home appliances, and then can issue requests to them. The proposed system has been implemented in a digital home testbed, revealing that it achieves high-quality home surveillance.
