Abstract

Radio-Frequency Identification (RFID) technology can provide global visibility for each product by the Discovery Service (DS) of EPCglobal, the de facto international standard for RFID. Only the role of a DS has been introduced and no concrete standard for a DS has yet been specified. A DS should have high scalability because of the huge volume of products and therefore tracing information. We propose a scalable distributed architecture for a DS that is Object-Based Discovery Service (OBDS). An OBDS consists of several unit-DSs and a Unit-DS Lookup Service (UDLS). A unit-DS contains all data for some objects and a UDLS enables the discovery of the desired unit-DS among distributed unit-DSs for global tracing of an object. We present an analytic comparison of several approaches for the DS and an experimental comparison of several approaches for designing a UDLS.
