Internet of Things (IoT)

Internet of Things (IoT)

Although the Internet of Things i.e. IoT seem to be a hot topic in industry today, it dates back to 2000 when Kevin Ashton, one of the pioneers of IoT, at MIT’s AutoID lab laid the foundation for it. He explored the way RFID could be linked to internet. He believed that objects in everyday life can communicate to each other and can be controlled by a computer if they were identified and outfitted with wireless connectivity1.
IoT can be defined as association of physical devices having embedded technology to converse and sense and/or intermingle with their internal states and/or the external environment. It seems IoT will enable things to be connected on demand anytime, everywhere, with anything. The IoT shall provide solutions based on the integration of hardware and software i.e. information technology to store, retrieve, and process data via communication of electronic systems between individuals or groups.
The fast convergence of information and communications technology is taking place at three layers of technology innovation: the cloud, data and communication networks, and devices.
It will be appropriate to understand building blocks (that simultaneously operate and communicate with each other) of IoT, illustrated in Figure 1a below:

While Figure 1b above depicts IoT connected devices as given in IHS-Markit IoT trend watch 20172
A number of technology enablers such as cheap sensors, bandwidth, processing, smart-phones wireless coverage, big data and IPv6 (the latest version of the Internet Protocol (IP) standard) will lead to billions of IoT connected devices reality soon. Cisco’s Internet of Things Group (IOTG) predicts there will be over 50 billion connected devices by 20203.

The journey of evolution of IoT is interesting i.e. from human to human up to machine to machine via worldwide web and internet of services (e-commerce) followed by people (social media).
By 2019, the global IoT market is forecast to be valued at more than 1.7 trillion U.S. dollars by Statista4
IoT is one of the most broadly discussed technological perceptions in today’s technology circles and is expected to radically change how we work as well as how we live. The technology required for controlling IoT devices going down while internet connectivity through smart-phones is increasing will lead to IoT as an all persistent technology in the coming next 10 years.
