Decreasing the effectiveness of GPS technology in indoor environments has necessitated the use of different and cheaper technologies in these environments. Today's indoor positioning systems tend to be developed using wireless medium technologies such as RFID, BLE, WLAN, Geo-Magnetism, UWB and mobile device technology. The fact that these technologies are more likely to be affected by the environment...
This paper presents a localization system for objects tagged with UHF-RFID passive tags, where the reader is attached to a drone. The system implements the phase-based SARFID technique to locate static tags with respect to a UHF-RFID reader attached to a commercial drone. The reader antenna trajectory is achieved through a Global Positioning System. The bi-dimensional tag position is estimated with...
Nowadays, parents are perturbed about school going children because of the increasing number of cases of missing students. On occasion, students need to wait a much longer time for arrival of their school bus. There exist some communication technologies that are used to ensure the safety of students. But these are incapable of providing efficient services to parents. This paper presents the development...
In this paper a system for increasing children's safety is proposed. The focus is on the daily route from home to school and vice versa, assuming the use of school buses. IoT paradigm is exploited together with different localization techniques i.e. RFID and GPS, in order to design a solution for parents willing to make certain of their child's following the main steps to school or home, i.e. taking...
Text clustering, as a significant field in natural language processing, is a key technology of processing and organizing massive text data. In the era of big data, however, the massiveness of data brings great challenge in aspects of time and accuracy of text clustering. This paper focus on the issue of speed and preciseness in text clustering combined with genetic algorithm, feedback and distributed...
In indoor localization environment, RFID signal propagation is complicated because of the reflection and diffraction and NLOS. The LANDMARC system and KNN algorithm cannot achieve satisfactory accuracy. By using the passive UHF RFID system, we propose an improved KNN method to rectify the target's coordinate position. First we use the traditional method to collect the reference tags RSSI and KNN algorithm...
This concept paper reviews relevant literature in order first to identify the most common features needed for an effective health care Real Time Location System (RTLS) and secondly to evaluate common RTLS technologies against this identified feature criteria in order to determine the most feasible technology. The most feasible set of technologies arising from this evaluation is considered for further...
In recent years, many companies want to keep track of personnel, sources and working machines due to various reasons. This is sometimes achieved for security purposes and sometimes for coordination and performance purposes. The purpose and requirements are the main factors that determine the shape of tracking. Such developed systems for this purpose have different technologies according to their requirements...
This study focused on location based pricing in the public transport system. Aim of this study is design a system which automatically obtain tickets information by entering and leaving the means of transportation without any interaction with any devices. The fare collection device in the vehicles detects the passengers' presence and initiates services unnoticed in the background. Similar study has...
This study presents a multiband compact microstrip antenna for portable wireless applications. The proposed antenna, in addition to wireless local area network and a global positioning system (GPS) channels, is utilised for inductive and capacitive near- and far-field ultrahigh-frequency and 2.4 GHz radio frequency identification (RFID) applications. The fabricated antenna works at 890 to 933 MHz,...
The paper discusses testing the RFID locator system in real traffic in a 1 km2 area of interest for localization. Digital processing of the signal, arriving to a 20-element antenna array at the individual receiving stations, is based on the direction on arrival (DoA) method. The achieved accuracy is typically within 1 m, thus the system met its creators' expectations. The paper describes the basic...
In this paper, an all-textile antenna integrated in military beret for global positioning system (GPS) and radio frequency identification (RFID) applications is proposed. The proposed antenna consists of a left handed circular polarization (LHCP) GPS patch antenna and a circular ring patch antenna with conductive threads to operate as RFID in 915 MHz Industrial, science and medical (ISM) band. The...
The paper explains how IoT processors can be used to implement Autonomous Long Distance Trains (ALDT) that can out-perform the traditional trains in four important areas, namely, (a) better safety to itself and to other trains (b) better safety to others like bridges, objects at level crossings etc (c) efficient service to the train users and (d) better environment for the Railway authorities to improve...
Embedded radio-frequency identification, sensor technologies, biomedical devices and a new breed of nanotechnologies are now being commercialized within a variety of contexts and use cases. As these technologies gather momentum in the marketplace, consumers will need to navigate the changing cybernetic landscape. The trichotomy facing consumers are: (1) to adopt RFID implants as a means of self-expression...
Maritime boundary violation and intrusion by fishing boats has been a huge concern not only for the errant fishermen and their families but also a massive burden on governments and public alike, due to the complexity of the issue and the naivety of the people involved. The chief solution is to safe guard these fishermen from the danger which they are encountering in everyday life for their livelihood...
Security for women has become a major issue in most of the countries. Survey results shows that every year around 25000 crime against women were booked across India. From the last ten years, the statistics among women abusement, sexual harassment have been steadily increasing. It has become mandatory to come up with a solution to protect the women from being a victim and to reduce the attacks. The...
Fingerprint localization algorithm is widely used in indoor scenario positioning. Received Signal Strength (RSS) is commonly used as the signal feature of fingerprint algorithm. But RSS could be changed due to the temperature or environment reason, which makes it an unreliable signal feature. This paper proposes a novel positioning algorithm based on the formal K Nearest Neighbor (KNN) algorithm....
Indoor localization has been an active research field for decades. Location determination is normally accomplished using the Global Positioning System (GPS) for outdoor environment. For indoor environment GPS does not work due to the lack of the sight line to satellite. Several technologies are deployed to construct an efficient indoor positioning system. A compromise between cost, accuracy and time...
