Abstract

With the evolution of the fifth-generation (5G) wireless network, the Internet of Things (IoT) has become a revolutionary technique that enables a diverse number of features and applications. It can able a diverse amount of devices to be connected in order to create a single communication architecture. As it has significantly expanded in recent years, it is fundamental to study this trending technology in detail and take a close look at its applications in the different domains. It represents an enabler of new communication possibilities between people and things. The main asset of this concept is its significant influence through the creation of a new world dimension. The key features required for employing a large-scale IoT are low-cost sensors, high-speed and error-tolerant data communications, smart computations, and numerous applications. This research work is presented in four main sections, including a general overview of IoT technology, a summary of previous correlated surveys, a review regarding the main IoT applications, and a section on the challenges of IoT. The purpose of this study is to fully cover the applications of IoT, including healthcare, environmental, commercial, industrial, smart cities, and infrastructural applications. This work explains the concept of IoT and defines and summarizes its main technologies and uses, offering a next-generation protocol as a solution to the challenges. IoT challenges were investigated to enhance research and development in the fields. The contribution and weaknesses of each research work cited are covered, highlighting eventual possible research questions and open matters for IoT applications to ensure a full analysis coverage of the discussed papers.

Highlights

With an extensive growth in demand for a higher throughput, larger capacity, and lower latency for users, the 5G network is greatly expected to fulfill the desired requirements [1]
The main areas covered in this study include healthcare, environmental, smart city, commercial, industrial, and infrastructural aspects of Internet of Things (IoT) applications
To the best of the author’s knowledge, no such work has been conducted where all of these aspects are collectively discussed while focusing on various IoT applications, i.e., healthcare, environmental, smart city, commercial, industrial, and infrastructural applications

Summary

Introduction

With an extensive growth in demand for a higher throughput, larger capacity, and lower latency for users, the 5G network is greatly expected to fulfill the desired requirements [1]. The principal advantage of IoT consists of its ability to enable communication between an infinite amount of machines incorporated into a large-scale wireless network [47]. These automated devices and sensors together produce and transmit information in real-time, which is useless in the case of incorrect or insufficient filtering and data processing. A hybrid IoT architecture consists of the things involved, followed by the insight data processes which end with the action that needs to be done (as shown in Figure 2) [49,50].
