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...

Volume 22, Article x, pp., January 2008 In today’s global competitive environment, organizations face a variety of challenges. Continuous improvement in organizational efficiencies and improving the entire supply chain are necessary to stay competitive. Many organizations are adopting radio frequency identification technologies (RFID) as part of their information supply chains. These technologi...

Radio Frequency Identification (RFID) is a system that uses radio frequency to transmit identification wirelessly. Its functionality is much more powerful than bar code system, with which a contacting reader must be used to read the bar code. RFID, on the other hand, may read the information stored in a tag with a non-contact reader from a distance as far as tens of meters. Health care industry...

In recent years, several retailers gained experience with the implementation and use of radiofrequency identification (RFID). Although extensive benefits through the use of RFID have been discussed in academia and practice for many years, strategic approaches to reach the promised targets still are largely unexplored. To support practitioners with using RFID in retailing, the reliability of dat...
