The Internet of Things (IoT): An Overview
Abstract
Information and Communications Technology (ICT) controls our daily behaviors. It becomes a main part of ourlife critical infrastructure bringing interconnection of heterogeneous devices in different aspects. Personal
computing, sensing, surveillance, smart homes, entertainment, transportation and video streaming are examples,
to name a few. [...] As a critical living entity, Internet is contentiously changing and evolving leading to emerging
new technologies, applications, protocols and algorithms. Acceleration of wireless communication trends brings
an ever growing innovation in Internet connectivity and mobile broadband. Infrastructureless communication
devices become ubiquitous, smart, powerful, connectible, smaller, cheaper, and easier to deploy and install. This
opens a new future direction in the society of ICT: the Internet of Things (IoT). Nowadays, the IoT, early
defined as Machine-to-Machine (M2M) communications, becomes a key concern of ICT world and research
communities. In this paper, we provide an overview study of the IoT paradigm, its concepts, principles and
potential benefits. Specifically, we focus on the IoT major technologies, emerging protocols, and widespread
applications. This overview can help those who start approaching the IoT world aiming to understand and
participate to its development.
