Layered OSGi-based Reconfigurable Lightweight RFID Reader Protocol

Radio Frequency Identification (RFID) systems are emerging as a practical means of auto-identification in a wide variety of applications in the modern era and as one of the most pervasive computing technologies in history. A typical RFID system is usually composed of four parts: tag, RFID reader, RFID middleware and application system. The host system seeking between the hardware and the enterprise system should introduce intelligent operational environment using configurable rules and lightweight, event driven architecture for smoothing and restricting high volume of raw events injected from the physical world. Such implementation should be part and parcel of a generic middle-ware platform to ensure an open environment and adaptability. To make the RFID reader integration uniform and effective, and meet the low calculation requirement of low-cost readers, a layered OSGi-based Reconfigurable Lightweight RFID Reader Protocol is presented here. Bearing in mind that the EPC standard has become a virtual standard of RFID system due to its rapid development, to meet the demand of EPC Reader Protocol Standard (RPS), the presented protocol is specified in four layers, respectively the Discovery Layer, the Reader Layer, the Tag Layer and the Notify Layer. Differ from EPCRPS, in which different Messaging/Transport Bindings provide for different kinds of transport, the Messaging Layer and the Transport Layer are no longer designed to be working in pairs. This protocol makes the reader integration uniform and effective.
