Abstract
RFID middleware is anticipated to one of the main research areas in the field of RFID applications in the near future. The Data EPC Acquisition System (DEPCAS) is an original proposal designed by our group to transfer and apply fundamental ideas from System and Data Acquisition (SCADA) systems into the areas of RFID acquisition, processing and distribution systems. In this paper we focus on how to organize and manage generic RFID sensors (edge readers, readers, PLCs, etc…) inside the DEPCAS middleware. We denote by RFID Sensors Networks Management (RSNM) this part of DEPCAS, which is built on top of two new concepts introduced and developed in this work: MARC (Minimum Access Reader Command) and RRTL (RFID Reader Topology Language). MARC is an abstraction layer used to hide heterogeneous devices inside a homogeneous acquisition network. RRTL is a language to define RFID Reader networks and to describe the relationship between them (concentrator, peer to peer, master/submaster).
Highlights
RFID technology has advanced significantly over the past few decades
These new situations require a more robust, flexible and complex middleware platforms in order to resolve issues at different layers of the communication architecture in different application contexts [3]. This complexity has brought up research issues in RFID middleware design that still pose a high entry cost for RFID technology adopters [4]
This work is devoted to describing the design and development details of an important part of the Data Electronic Product Codes (EPC) Acquisition System (DEPCAS) middleware: the so-called RFID Sensors Networks Management (RSNM), which is especially concerned with how generic RFID sensors are organized and managed
Summary
RFID technology has advanced significantly over the past few decades. Rapid advances in microelectronic transceivers have reduced the size and costs of HF and UHF RFID infrastructure, permitting longer reading ranges and faster reading rates than ever before. RFID technology is able to deal with novel applications with higher mobility and large numbers of tagged objects and software and hardware elements enable specific functionalities and general services [1] and offer important advantages over other identification mechanisms [2] These new situations require a more robust, flexible and complex middleware platforms in order to resolve issues at different layers of the communication architecture in different application contexts [3]. There is a lack of implementation details in this previous article that can be considered as a starting point of the work presented here In this sense, this work is devoted to describing the design and development details of an important part of the DEPCAS middleware: the so-called RFID Sensors Networks Management (RSNM), which is especially concerned with how generic RFID sensors (edge readers, readers, PLCs...) are organized and managed.
