Internet of Things: Surveys for Measuring Human Activities from Everywhere

Abstract

The internet of things (IoT), also called internet of all, is a new paradigm that combines several technologies such as computers, the internet, sensors network, radio frequency identification (RFID), communication technology and embedded systems to form a system that links the real worlds with digital worlds. With an increase in the deployment of smart objects, the internet of things should have a significant impact on human life in the near future. To understand the development of the IoT, this paper reviews the current research of the IoT, key technologies, the main applications of the IoT in various fields, and identifies research challenges. A main contribution of this review article is that it summarizes the current state of the IoT technology in several areas, and also the applications of IoT that cause side effects on our environment for monitoring and evaluation of the impact of human activity on the environment around us, and also provided an overview of some of the main challenges and application of IoT. This article presents not only the problems and challenges of IoT, but also solutions that help overcome some of the problems and challenges.

Analysis, Design, and Manufacture of a Compact UHF RFID Tag Antenna for Operating in a Metallic or Non-Metallic Environments

“…It is set on the economical FR4 substrate and has a dimension of 46 x 21,63 x 0,8 mm 3 .in the case of operating in a free space. It can even work in metallic environment with the enlargement of the substrate of 2.5mm from each side which means a total size of 51 x 26,63 x 0.8 mm 3 . It provides a stable performance when it is placed in a metallic milieu and reached a measured read range of 6.5m.…”

“…The folded dipole, which modifies the electrical length, is directly coupled to the π-structure resulting reduction of the physical size of the antenna and consists of a dipole, having a width of 0,75 mm, bent into a serpentine shape structure. The radiating element of the tag is printed on a thin, single-layer and inexpensive FR4 substrate (permittivity Ɛr=4.4 and loss tangent tanδ=0.0025) with a thickness of h=0.8 mm and a total area of 46x2,63x0,8mm 3 . The antenna design is simulated using CST (Computer Simulation Technology) microwave studio [26], whose numerical analysis is based on the Finite Integration Technique, and the optimized parameters are enlisted in Table 1.…”

“…Radio-frequency identification (RFID) is considered as the most significant identification technology, because it is exploited in a wide range of fields such as positioning and identification of objects [1] or health monitoring with wearables [2], the Internet of Things [3] and communication with different sensors military, passport, supply chain, and so on [4]. This makes it inescapable in the daily life of the person.…”

{Cloud, IoT}-powered smart weather station for microclimate monitoring

“…The advances made in many related areas including hardware technologies, sensor development, software engineering and networking implementations have contributed to the development of IoT. On the hand, research on Mobile Computing (MC), Pervasive Computing (PC), Wireless Sensor Networks (WSN), and Cyber Physical Systems (CPS) have also being carried out in parallel to IoT with the objective of making this planet a smart one [18,19]. Though, the above fields appear to work with different objectives and applications, they have several things in common and rely upon many common underlying technologies including real-time computing, machine learning, security, privacy, signal processing and big data analytics [18,20].…”

A New Scheme of Group-based AKA for Machine Type Communication over LTE Networks

“…However, these types of services and new types of services and technologies are available on request. Of all these, MTC is the most important issue in the fields of standardization and industry [2]. Many standards exist from the level components, speaking different radio interfaces, different choice routed or mesh networks, or offer a choice of identity systems.…”
