Localization And Tracking

Radio frequency identification (RFID) is poised for growth as businesses and governments explore applications implementing RFID. The RFID technology will continue to evolve to meet new demands for human and target location and tracking. In particular, there are increasing needs to locate and track multiple RFID-tagged items that are closely spaced. As a result, localization and tracking techniques with higher accuracy yet low implementation complexity are required. This paper examines the applicability of direction-of-arrival (DOA) estimation methods to the localization and tracking problems of passive RFID tags. Different scenarios of stationary and moving targets are considered. It is shown through performance analysis and simulation results that simple DOA estimation methods can be used to provide satisfactory localization performance.

This paper presents methods of localization of mobile systems using recent Radio Frequency Identification (RFID) technology. We consider an indoor environment where RFID tags are implanted along the wall or in objects in the room. If the absolute position and orientation of a tag are read by an RF reader, a mobile system can estimate its location using the information saved in the tags. A reader-tag model is obtained through experiments in order to derive relative positions and orientations between an antenna and an RFID tag. To estimate the location, we propose two estimation methods. One uses a single RFID tag and the other uses multi-RFID tags. Experimental results show that the proposed methods can provide good performance for mobile system localization in an indoor environment.

Radio Frequency Identification (RFID) is a common technology for identifying objects, animals, or people. The main form of barcode-type RFID device is known as an Electronic Product Code (EPC) and the most popular standard for passive RFID tags is Class-1 Generation-2. In this technology, the information transmitted between devices is through the air, therefore adversaries can eavesdrop these messages passed on the insecure radio channel and finally, the security of the system can be compromised. In this chapter, the authors analyze the security of EPC Class-1 Generation-2 standard, showing its security weaknesses and presenting some possible countermeasures.

In this paper, the use of passive Radio Frequency Identification (RFID) as a support technology for mobile robot navigation and environment mapping is investigated. A novel method for localizing passive RFID tags in a geometric map of the environment using fuzzy logic is, first, described. Then, it is shown how a mobile robot equipped with RF antennas, RF reader, and a laser range finder can use such map for localization and path planning. Experimental results from tests performed in our institute suggest that the proposed approach is accurate in mapping RFID tags and can be effectively used for vehicle navigation in indoor environments.

Radio Frequency Identification (RFID) technology enables wireless communication between a RFID reader and a RFID tag. One type, passive RFID tags, need no battery, being powered from the RFID reader's radio frequency signal. Passive RFID tags can support memories that can be used to store portions of the patient's medical history. One form factor for passive RFID tags is an employee ID (used for wireless access) or credit card form factor. This form factor allows the patient to carry their medical information with them. RFID benefits include providing information to Emergency Medical Technicians (EMTs), maintaining a patient's vaccination history and providing emergency contact information, all in a clear and unmistakable format. This simplifies information exchange during patient transfers, a cause of many preventable medical mistakes and errors. Cheap and simple systems, such as the one presented in this chapter, can reduce stress and prevent possible errors. Such systems with an intuitive human-machine interface can reduce the duration of a patient visit throughput. This system can prevent simple errors such as the administration of the wrong drug, dose, or drug omission, which is a major issue in hospitals. This requires that information be stored in a standardised manner, with limited healthcare provider access and use to protect patient privacy. This chapter explores the use of passive RFID tags to store medical information about a patient, with specific focus on storage of a child's vaccination history and safety.

Localization Performance

Radio frequency identification (RFID) is a promising technology for localization in various industrial applications. In RFID localization, accuracy is the top performance concern, and it is affected by multiple factors. In this paper, we investigate how the facility geometry impacts the expected localization accuracy in the entire region where the target is uniformly distributed. Three groups of geometries, namely, rectangles with various length-to-width ratios, circle, and regular polygons with 3–10 edges, are chosen for this study. A hybrid multilateration approach, which combines linearization and nonlinear optimization, is used to estimate the target location. Since the layout of landmarks significantly affects localization performance, we evaluate the expected accuracy in a facility obtained under the optimal landmark layout for the facility. The optimal landmark layout for each type of facility geometry is obtained, and then the effect of geometry is studied by comparing the expected accuracies of these layouts. It is discovered that (1) the optimal layouts follow several simple empirical deployment principles, (2) for all geometries, the expected accuracy improves and tends to reach the expected Cramer-Rao lower bound as more landmarks are used, and (3) if the same numbers of landmarks are used, the expected accuracies for circular and regular polygonal geometries are close. However, the expected accuracy for a rectangular geometry decreases as the length-to-width ratio increases.

Abstract Radio frequency identification (RFID) is one of the commonly used approaches to a short-range wireless data exchange. Numerous passive RFID tags are available on the market, and in a vast majority of cases, their designs are based on flat meandered dipole architectures. However, besides technological advantages, those realizations suffer from polarization mismatch issues and limited spatial sectors, from which flat tags can be interrogated. Here, we demonstrate and analyze a miniature omnidirectional tag accessible from all 4π stereo angles with a commercial RFID reader.

The features of the author’s patented method for determining the coordinates of moving objects using radio frequency identification tags (RFID tags) are studied, in which the coordinates of their constant position on the object’s path are recorded. On a moving object (personnel, warehouse forklift, car, etc.), RFID tag readers are installed that interact with RFID tags installed on the ground and read their coordinates. Thereby, the coordinates of a moving object on the track are accurately and quickly determined. A methodology for choosing an implementation option is proposed and examples of applying the obtained results in mines, warehouses, on automobile routes, for civil and dual-use systems are given. The necessity of using passive RFID tags and a circularly polarized reader antenna is established. The resulting solution has no real restrictions on the speed of moving objects.

Package Labeling

This article discusses the topic of labeling postal shipments by passive radio frequency identification (RFID) tags. Every delivery company needs to have all necessary information for every single postal shipment package it carries. Shipment package labeling is essential for processing and tracking the postal shipments along its delivery process. Using RFID technology for the process brings advantages in more efficient delivery and data collection along with regular information updates of shipment status across complete delivery chain.In this article, we focused on the problem of logical log of key shipment package information into EPC memory of the RFID smart label. We have taken into account the National postal administrator and its current system of shipment labeling. In the end, we presented a design for conversion of contemporary labeling using bar codes into labeling using RFID tags.
