Architecture Research And Prototype Implementation Of RFID Object Naming Service

RFID (Radio Frequency Identification) is a non-contact automatic identification technology. Using RFID the objects in rapid movement are identifiable, a number of labels can be identified simultaneously. The speed and convenience of operation, without manual intervention are also the advantages of RFID. With the maturity of RFID technologies and standards, RFID industry is developing rapidly in recent years coupled with the support of national policies.Combination of RFID and Internet to build RFID Networks is an important trend of RFID application. RFID Object Naming Service provides the mapping between electronic label and information service, which is the core and foundation of the RFID Networks operation. The Object Naming Service specifications framed by some international RFID standards organizations are deficent in distribution, scalability and multiple-code compatibility of service architecture. Designing a reasonable architecture of RFID Object Naming Service is an urgent task for developing RFID standards and building RFID Networks.The concept, composition and workflow of RFID Object Naming Service are first introduced. Based on the discussion of existing relevant standards, this thesis focuses on the architecture design of RFID Object Naming Service. With in-depth analysis of the existing architectures, the hash based hierarchical architecture is presented, with advantages in distribution, scalability and manageability. Then key issues of dynamic expansion, cache update and multi-code compatibility are analyzed based on the architecture. Then the prototype for RFID Object Naming Service is implemented in Linux platform using modular, multi-thread, and other mechanisms. Software testing is done for the prototype system at the end.The prototype system for RFID Object Naming Service based on the hash based hierarchical architecture is implemented, which provides a convenient platform for RFID Object Naming Service research.
