Abstract
LLRP (Low-Level Reader Protocol) specifies an interface between RFID readers and RFID applications, also called LLRP servers and clients respectively. An LLRP server should concurrently execute various functions. This paper designs an LLRP server of a multi-threaded architecture. For that, (i) the operational procedure between LLRP servers and clients is investigated, (ii) the functional requirements of LLRP servers are presented, (iii) the operation of an LLRP server is decomposed into several threads to satisfy those functional requirements, and (iv) the operational procedure is further examined in thread-level. To validate the designed architecture, it is modeled and simulated by using the DEVS formalism which specifies discrete event systems in a hierarchical, modular manner. From the simulation result, we can conclude that the proposed architecture conforms the LLRP standard and satisfies all the given functional requirements.
