INTERNET OF THINGS AND APPLICATIONS
- 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.
Several IoT protocols have been introduced to provide an efficient communication for resource-constrained applications. While developers employ existing technologies to build the IoT, research groups are working on adapting protocols to the IoT in order to optimise communications.
To address this issue, we evaluated and compared several communication protocols, namely, MQTT, SMQTT, AMQP, CoAP, XMPP, DDS, RESTful and WebSocket and we discuss their suitability of the IoT protocols by considering architecture, security, message techniques and QoS aspects.
Lastly, we provide our conclusions for the IoT communication protocols according to the study that we have conducted.
The existing 4G networks have been widely used in the Internet of Things (IoT) and is continuously evolving to match the needs of the future Internet of Things (IoT) applications.
The 5G networks are expected to massive expand today’s IoT that can boost cellular operations, IoT security, and network challenges and driving the Internet future to the edge.
The existing IoT solutions are facing a number of challenges such as large number of connection of nodes, security, and new standards.
This paper reviews the current research state-of-the-art of 5G IoT, key enabling technologies, and main research trends and challenges in 5G IoT.
