Structure of Middleware in RFID Based System： Application to the Infant Protection

This paper introduces a middleware design and implementation for an infant protection system-maternal infant safety and surveillance(MISS), using radio-frequency identification(RFID) technology. The middleware is located between application level and hardware-device level in the hierarchical software structure, which is in further divided into three levels, i.e. data, logical and service respectively. The rationale for the design is based on the consideration of the performance, organization,maintenance, and upgrade factors.
