RFID system is a wireless technology that can transfer data between tags and readers via radio frequency. In an RFID network, readers are located close to each other to obtain optimal connectivity and sufficient coverage. In such an environment, which is called dense reader environment (DRE).Different types of collisions such as Reader-to-Reader and Reader-to-Tag ones, often lead to serious pro...

In this paper we use the implementation of radio frequency identification (RFID) in various sectors of the healthcare industry as an illustration and application of how academics and managers may assess the potential for new technologies to be sustaining or disruptive to an organization. We review RFID technology, summarize literature related to disruptive innovation, develop a qualitative fram...

Anti-collision algorithms of active RFID system are studied and simulated by the OMNeT++ software. The active RFID system based on ZigBee RF module is analyzed firstly, which uses the anti-collision mechanism involving the CSMA/CA algorithm of IEEE 802.15.4 protocol. Given the IEEE 802.15.4 simulation framework and configurations on the OMNeT++ simulation platform, simulations and analyses abou...

Radio frequency identification systems with passive tags dramatically increase the ability of an organization to acquire a vast array of data about the location and properties of any entity that can be physically tagged and wirelessly scanned within certain technical limitations. However, if multiple tags are to be identified simultaneously, messages from the tags can collide and cancel each ot...

In some applications, the bearer of a radio frequency identification (RFID) tag might change, with corresponding changes required in the RFID system infrastructure. We survey the security requirements for RFID tag ownership transfer, and propose novel authentication protocols for tag ownership and authorisation transfer. The proposed protocols satisfy most of the requirements that we present, a...

In today’s global competitive environment, organizations face a variety of challenges. Many organizations are adopting radio frequency identification technologies (RFID) as part of their information supply chains. These technologies provide many benefits to the organizations that use them. However, how these technologies affect consumers and their willingness to adopt the technology is often ov...

This paper investigated various indoor positioning techniques and presented a comprehensive study about their advantages and disadvantages. Infrared, Ultrasonic and RF technologies are used in different indoor positioning systems. RFID positioning systems based on RSSI technology are the most recent developments. Positioning accuracy was greatly improved by using integrated RFID technologies.

With the increased radio frequency identification (RFID) applications different authentication schemes have been proposed in order to meet the required properties. In this paper we analyze the security of a server-less RFID authentication protocol which is proposed by Deng et al. in 2014. Deng et al. proposed an improvement over Hoque et al. protocol to overcome its vulnerability against data d...

The purpose of this study is to compare the organizational adoption factors of Radio Frequency Identification (RFID) between adopters and non-adopters in mandatory and voluntary environments respectively. This paper presents the result of an empirical study that investigates the adoption behaviour of livestock farms in relation to RFID technology adoption in the context of Australia. The quanti...

The suitability of application Radio Frequency Identification (RFID) Systems in the supply chain has been discussed since the late nineties. Like any new innovation, there are advantages (in operational efficiencies), and disadvantages (in its implementation). The hype created by this innovation suggests that advantages outweighed the disadvantages. Yet, adoption has lagged most predictions. Th...
