An object-oriented implementation of a Low Level Reader Protocol (LLRP) library

Abstract

This Master of Engineering Thesis describes the design and implementation of an object-oriented Low Level Reader Protocol (LLRP) library. LLRP is a recently released protocol which standardizes the formats and methods of communication between RFID Readers and Clients and aims to become the global standard for Reader management in RFID systems. LLRP provides a standard Reader - Client interface by defining a. number of Messages in binary format, which Clients and Readers can each send and receive. This implementation uses a nested object model to represent all the Messages and Parameters defined in the LLRP specification. It also provides a serialization module, which converts Message and Parameter objects to the binary format described in the LLRP specification and vice versa. The use of this object model simplifies the implementation of Client logic and makes it easier to develop rich Client applications without having to deal with the low level details of the LLRP interface.
