Enhancing RFID system configuration through semantic modelling

Abstract

Radio-Frequency Identification (RFID) system technology is a key element for the realization of the Industry 4.0 vision, as it is vital for tasks such as entity tracking, identification and asset management. However, the plethora of RFID systems’ elements in combination with the wide range of factors that need to be taken under consideration along with the interrelations amongst them, make the problem of identification and design of the right RFID system, based on users’ needs particularly complex. The research outlined in this paper seeks to optimize this process by developing an integrating schema that will encapsulate this information in a form that is both human and machine processible. Human readability will allow a shared understanding of the RFID technology domain; machine readability, automated reasoning engines to perform logical deduction techniques returning implicit information. For this purpose, the novel RFID System Configuration Ontology (RFID SCO) is developed. Hence, non-RFID experts are enabled to identify the most suitable RFID system according to their needs and RFID experts to retrieve all the relevant information required for the efficient design of the corresponding RFID system. The RFID SCO is validated and tested successfully against real-world scenarios provided by domain experts.

Effect of Human Body to the Read Range of Wireless Communication Devices and Wearable Antenna Worn in Close Proximity

“…The read range for active tags is longer than that of passive tags as active tags are powered by a power source. The read range for passive tags depends on frequency of operations, type of reader and tags, interference, and surrounding environments (Tsalapati et al, 2021).…”

Special issue on ontologies and standards for intelligent systems: editorial

“…In the next paper of this special issue ('Enhancing RFID system configuration through semantic modelling'), Tsalapati et al (2021) proposes a domain ontology for the configuration of radio-frequency identification (RFID) systems, which are a key element of the Industry 4.0 for data exchange within the realm of the internet of things (IoT). The ontology is thus an extensive formal representation of RFID technologies, and its formal semantics is defined by using a knowledge representation language to ensure a precise specification of the meaning of the described elements that is both machineand human-readable.…”
