Abstract
The Internet of Things (IoT) has changed the worldwide network of people, smart devices, intelligent things, data, and information as an emergent technology. IoT development is still in its early stages, and numerous interrelated challenges must be addressed. IoT is the unifying idea of embedding everything. The Internet of Things offers a huge opportunity to improve the world’s accessibility, integrity, availability, scalability, confidentiality, and interoperability. However, securing the Internet of Things is a difficult issue. The IoT aims to connect almost everything within the framework of a common infrastructure. This helps in controlling devices and, will allow device status to be updated everywhere and at any time. To develop technology via IoT, several critical scientific studies and inquiries have been carried out. However, many obstacles and problems remain to be tackled in order to reach IoT’s maximum potential. These problems and concerns must be taken into consideration in different areas of the IoT, such as implementation in remote areas, threats to the system, development support, social and environmental impacts, etc. This paper reviews the current state of the art in different IoT architectures, with a focus on current technologies, applications, challenges, IoT protocols, and opportunities. As a result, a detailed taxonomy of IoT is presented here which includes interoperability, scalability, security and energy efficiency, among other things. Moreover, the significance of blockchains and big data as well as their analysis in relation to IoT, is discussed. This article aims to help readers and researchers understand the IoT and its applicability to the real world.
Highlights
FC data is obtained from sensors connected to physical devices in an Internet of Things (IoT) platform The FC model uses local computing services located at the network edge rather than C
IoT developers and researchers are collaborating to bring these technologies to a wider audience and to benefit society as much as possible
IoT must allow seamless communication anywhere, for anyone and anything. This includes detecting, sensing, networking, encoding, and visualization capabilities. This concept has opened up a slew of new possibilities for large-scale service and product development, resulting in many new ideas and business opportunities
Summary
We have chosen a large number of research papers, and this article primarily outlines and provides an overview of the life-changing phenomenon of the Internet of Things, as well as the various technologies, challenges, and real-world applications that it has spawned, which have revolutionized our world with its wide-ranging outlook. The remarkable recent developments in IoT technology have provided the opportunity to broadly deploy tiny sensors for wireless communication for various applications such as smart homes, smart cities, smart healthcare, and the smart industry [13] The motivation behind this contribution is that in critical situations, IoT devices can effectively deliver highly secure information, less power consumption, and low-cost solutions to the wireless network.
