Internet of things a to z
Information and communication technology (ICT) has always been dynamic
and evolutionary in nature, leading to the continuous emergence of new
technologies and business models. The recent advances in terms of available
computing resources, software systems and communication networks, and the
continuing miniaturization of hardware components have made it possible to
integrate ICT into virtually anything, thus leading to the rise of a new computing
paradigm known as the Internet of Things (IoT). The IoT aims at realizing an old
dream of turning everyday objects into smart ones that are interconnected via
the Internet and able to collect and exchange data and to make decisions
autonomously. This additional “smartness” covers both the communication
infrastructure and applications, including monitoring systems, industrial automation,
and ultimately smart cities. In a recent report, Gartner estimates that
there will be 11.2 billion connected devices in use in 2018 and 20.1 billion in
2020.1 This clearly demonstrates the great potential and importance of this
model and is also the motivation behind this book.
