This paper presents a new auditing system scheme based on radio frequency identification technologies for cryopreservation applications using liquid nitrogen at temperature of -196°C. Conventional approaches such as hand written labels or printed barcodes suffer from the significant manual labor work and freeze-thaw-damaging risk of the sample. The proposed scheme integrates miniaturized RFID electronic devices and antennas in the thin cryogenic straws without significantly changing their dimensions. In addition, 900 MHz frequency band is chosen for long reading range, which eliminates the need to take the preserved biological samples out of liquid nitrogen and minimizes the damaging risk. Four most important technical aspects for the system have been identified and investigated: 1. The link budget is evaluated by FDTD numerical simulations to make sure the RF signal strength meets the requirement for the reading range. 2. The total efficiency of small and tightly coupled RFID dipole antennas is studied and obtained by simulations. 3. The current-voltage behaviors of two types of transistors in typical RFID electronics have been characterized by measurements to identify the suitable transistor type for reliable circuit designs at -196°C. 4. The easy-to-access and anti-collision reading system for fast data collection is analyzed. The obtained results indicate that the proposed scheme is feasible, which can be beneficial for the relevant scientific fields.

In this paper it is shown that a conductive feed used to excite a standing surface wave on a metallic object can be used to reliably power a passive UHF RFID sensor tag mounted to the same. The read rates of this method and that of free space are compared. Findings show that along the metallic bar structure, and for a greater distance, minimum read rates were at least 9 times greater than in free space. The maximum read rates were found to be around 20 times larger than in free space. It is shown that by utilizing the metallic structure itself, as a secondary nearfield antenna, it is possible to read accelerometer sensor data effectively from a passive UHF sensor tag such as the WISP 5.0. Such a technique may provide a low cost alternative to traditional SHM systems.

This paper presents a multi-antenna approach of the phase-based SARFID method to locate static tags by employing two UHF-RFID reader antennas installed on an Unmanned Grounded Vehicle (UGV). The UGV is remotecontrolled and equipped with Laser Range Finder sensors to move inside an indoor environment, and the knowledge of its trajectory is achieved through a Simultaneous Localization And Mapping procedure. By processing the phase data collected from each reader antenna, different matching functions can be obtained and combined to improve the estimation of the bidimensional tag position. Differently from other localization techniques, neither reference tags (anchor tags), nor large phased array antennas are required.

In this paper, an approach to the simultaneous two dimensional localization of 16 LF-RFID transponders is proposed. The underlying hardware setup as well as the localization algorithms are explained. Prior to the localization, the transponders must be programmed with a special modulation pattern. A detailed discussion on the modulation pattern and the synchronization of the signals is given. The advantage of the proposed method is that no complex bi-directional communication protocol or anti-collision method needs to be employed. The theoretical amount of simultaneously localizable transponders is limited to 64 by the size of the transponder memory. Using a laboratory setup consisting of a wooden shelf with 16 compartments, the localization and identification method is demonstrated with 16 transponders. Limitations of the method are pointed out and probabilities of failures are measured. The robustness of the method is shown with metallic components being added to the shelf.

Passive radio-frequency identification (RFID) tags are widely used due to its economic cost and satisfactory performance. So far, passive RFID tags are mostly applied to identify certain objects, such as underground pipe identification under buried conditions. However, there is lack of study on the application of buried tags for further application. In this paper, the performances of buried RFID tags are studied to develop a flooding warning system based on RFID tag array for energy facility such as power stations. In this study, the corresponding signal strength received by the RFID reader is evaluated when the RFID tags are buried by seven materials respectively. The results show that flood warning detector can be constructed using passive RFID tag array and reader.

Indoor is one of the most complicated propagation environments depending on the specific type of buildings structure. In this paper, we present a combination of 2 models using active UHF-RFID tags at 433 MHz: The Dual One Slope Model (DOSM) and the Dual One Slope with Second Order Polynomial Model (DOSSOM). Further, a comparison with different propagation models have been proposed. Our work aims to study, analyze and improve the accuracy of the two new path loss models. Distance errors are determined based on all different propagation models. According to experimental validations, the mean distance error had a value 56 cm using the DOSM, whereas, it had a value of 51 cm using the DOSSOM. In short, distance errors derived from the two new empirical path loss models (DOSM and DOSSOM) closely match real measurements. Thus, referring to the mean distance errors already reached, the stability of our new indoor propagation models will be affirmed.

The rapid development of the land-based edge computing architecture has pushed the horizon of a new processing mode, which transfers the big data processing from the cloud to the edge side. In the contex of mobile edge computing, combined with the idea of collaborative cooperation, we put forward a maritime mobile collaborative edge communication model. A novelty of the model is the addition of a new level of collaborative edge as a small-type processing center between the cloud and the edge sides. For the sake of high efficiency in task scheduling of the collaborative edge part, we adopt an improved Cooperative Co-evolution Algorithm to overcome the constraints of marine environment and communication costs. In order to make the complex matters simplify, this paper adopts the divide-and-conquer strategy and transforms the scheduling optimization problem into the issue of seeking the best individual set of subpopulations. Simulation results verified the performance of the solution.

There are a large number of RFID chip sets on the market. These chip sets cover the most widely deployed RFID technologies. These chip sets enable the rapid development of RFID readers as well as the inclusion of RFID into other devices. These market offerings frequently require an ancillary microprocessor to undertake the anti-collision algorithm in conjunction with the RFID chip set. These chip sets largely act simply to provide an RF front end with some encoding, decoding, protocol framing and CRC checking to support the overall activity. This paper presents the current state of the RFID chip set market and argues that these offerings fall short of what is required from a genuine RFID solution-on-chip (SoC). Alternatives, including a genuine RFID SoC and dedicated RFID ASIC implementing anticollision algorithms are proposed.

Vehicular Ad Hoc Network (VANET) plays an important role in the future development of Intelligent Transportation System (ITS). VANET has provided a promising solution for building smart roads. Besides, Radio Frequency Identification (RFID) is more widely used in the field of urban transportation to facilitate smart parking and Electronic Toll Collection (ETC). In this paper, we consider RFID-Integrated VANETs to monitor traffic flow, detect road accidents, and help avoiding chain crush. The deployment of Road Side Units (RSUs) at roadsides in VANETs, which send the accident information to the drivers timely on the city road, enhances the road safety. This paper investigates the placement problem of Base Stations (BSs) and RFID-reader-embedded RSUs to achieve an efficient network design by considering communication constraints, coverage requirement, connectivity of tree-based architecture and network characteristic. We formulate the problem as an Integer Linear Programming (ILP) and solve it by Gurobi. Simulation results show that our proposed architecture is cost-effective and scalable to different scenarios in practice.
