Survey: Classification of the IoT Technologies for Better Selection to Real Use

Nowadays, more and more devices are connected to the Internet labeled as the Internet of Things (IoT). They are used everywhere and anytime to improve our everyday life and make processes easier. In our work, we specify the term of IoT for better understanding. These systems are usually powered by batteries, which is critical to power consumption. Each team, researcher or expert should consider it while designing the new application or solution for uses in the area of the Internet of Things. Therefore, we provide a brief survey and introduce the classifications for IoT technologies, specifically IoT devices and processors, communication technologies, and security protocols used in such networks. We focused primarily on power consumption, and according to that, we specified rules or criteria for a better selection of the related technology. In the end, we described the application of the IoT solution into real life in the area of healthcare.
