Introductory Chapter: Internet of

Things (IoT) Importance and Its

Internet of Things is a recent technology that creates a global network of machines and devices that are capable of communicating and exchanging data with each other through the Internet. There is a difference between the Internet of Things and the Internet. Internet of Things can create information about the connected objects, analyze it, and make decisions; in other words, one can tell that the Internet of Things is smarter than the Internet. Security cameras, sensors, vehicles, buildings, and software are examples of things that can exchange data among each other.

As the number of real-time applications (devices) that need smart connections among each other is increased, the Internet of Things challenges will also increase.

Sensors and devices that are connected and communicated together through the Internet of Things infrastructure may need to update their trends or feature to be suited to the changes of surrounding environments. The Internet of Things is a smart infrastructure that can process the collected data and make the required decisions to improve itself and to change the trends or features of the connected devices to accommodate the surrounding environments' changes. Internet of Things is a smart technology that helps all connected devices to update themselves according to changes in the surrounding environment and to be able to be adopted and work in any other strange environment with high accuracy. As a result, smart connected system can be produced if smart infrastructure is well designed to treat the col-

The main idea of using the Internet of Things is to have a smart system and to connect billions of devices over the whole world. The expected devices to be connected together are expected to be 50 billion through the Internet of Things devices by 2020. **Figure 1** shows the growth of the world population and the connected devices by 2020. Connecting such a huge number of devices required high-security

lected data from devices correctly, to make the needed decisions.
