“The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it."
-Dr. Mark Weiser, Father of Ubiquitous Computing
Introduction
Each day the amount of data produced is humongous. Each second, the present-day Internet allows massively heterogeneous traffic through it. This network traffic consists of images, videos, music, speech, text, numbers, binary codes, device status, banking messages etc and all these devices through the network for the transmission of data
Data from sensors and actuators, healthcare data, data from vehicles, home automation system status and control messages, military communications, and many more. This huge variety of data is generated from a massive number of connected devices, which may be directly connected to the Internet or connected through gateway devices This modern-day dawn of network-connected devices has given rise to the popular model of the Internet Of Things
IoT is an anytime, anyplace, and anything system or network of physical objects with Internet access that can sense their surroundings and make intelligent changes to those surroundings. On the "things" connected to the Internet, low-power, low-form-factor embedded CPUs are typically used to do this. In other words, the Internet of Things (IoT) can be thought of as a collection of interconnected machines, tools, and gadgets. These items are made up of sensors, actuators, and processors, which communicate with the Internet via wireless technologies. Another school of thought likewise believes that the IoT paradigm is inherently dependent on wired Internet access. For the sake of consistency, we shall refer to any technology—wired or wireless—allowing connection to the Internet in this book as an IoT-enabling technology.
Networking
IoT devices use basic principles of Computer Networking and basic terminologies (FTP, HTTPS, IP, SMTP) and technologies (LAN, WAN, MAN, PAN ) many more. The intercommunication between any two devices whether it's small scale or large scale the set of information has to pass through Layered Network Models like:
ISO-OSI which is popularly called the OSI model
TCP/IP Suite (Internet Protocol Suite )
It also uses different addressing terminologies for uniquely identifying the systems using an IP address or MAC address so these ideas on what two systems must come across in order to establish a connection between two systems
Associated IOT technologies
Cloud Computing
Conversational AI Eg: Alexa, Cortana, Google Assistant
Fog Computing
Future of IoT
1.🌽IoT in Agriculture 🥬🍎
At the moment, IoT-enabled technologies are widely employed to increase agricultural output, generate significant money, and improve farming efficiency. Precision farming benefits from the advancement of the IoT paradigm. Crop health monitoring, water management, crop security, farming vehicle tracking, automatic sowing, and automatic pesticide spraying are all functions of agricultural IoT systems. Different sensors must be installed over agricultural fields in an IoT-based agricultural system, and the detected data from these sensors must be communicated to a centralized entity such as a server, cloud, or fog device. These data must also be processed and evaluated in order to deliver various agricultural services. Finally, these services should be accessible via mobile devices or laptops.
2.In Vehicles 🚗 🚀
The use of connected vehicles is rapidly expanding around the world. As a result, the number of on-road accidents and traffic mismanagement is on the rise. The increasing number of vehicles creates a parking issue. However, the evolution of IoT aids in the formation of a connected vehicular environment to efficiently manage transportation systems. Vehicular IoT systems have infiltrated various aspects of the transportation ecosystem, including on-road and off-road traffic management, driver safety for large and small vehicles, and public transportation security. Vehicles in a connected vehicular environment are capable of communicating and sharing information. Furthermore, IoT allows a vehicle to sense its internal and external environments to make autonomous decisions. the best example is the self-driving cars by Tesla which are already ahead

3.IoT in Healthcare🚑
The salient features of IoT encourage researchers and industries to develop new IoT-based technologies for healthcare. These technologies have given rise to small, power-efficient, health monitoring and diagnostic systems. Consequently, the development of numerous healthcare technologies and systems has rapidly increased over the last few years. Currently, various IoT-enabled healthcare devices are in wide use around the globe for diagnosing human diseases, monitoring human health conditions, and caring/monitoring for elders, children, and even infants. Moreover, IoT-based healthcare systems and services help to increase the quality of life for common human beings; in fact, it has a promising scope of revolutionizing healthcare in developing nations
IoT is a very broad topic it is interconnected to AI/Machine Learning and it is growing day by day as there are each new research papers published on AI/ML and ideas are being invented each and every day so definitely wireless communications are going to dominate in the future (well it have already started :)
