Internet of Things

WHAT IS INTERNET OF THINGS?

Internet of Things envisions a wide network of interlinked computing devices, including both

digital and mechanical devices. The connection between these devices is powered through the

internet where each device carries unique identifiers to communicate with other devices. These

“things” or objects are designed in such a way that they can engage in communications without

manual intervention. The linked network, where automation systems and connected devices

work together, provides a modern outlook for a futuristic world where data could be collected

and analyzed to perform the right action.

The term IoT is used primarily associated with devices that were not supposed to be con-

nected to the internet in the first place. For example, PCs, internet and laptops are known to have

an internet connection. On the other hand, a smartwatch can be considered as an IoT-powered

device.

BRIEF INTRODUCTION TO VARIOUS

TECHNOLOGIES USED IN IoT

There are various technologies involved in IoT. These technologies are placed at dierent tiers.

Every tier under a technology stack requires communication and integration with the rest of the

tiers of the existing stack. The stack of IoT is also known as the Thing Stack. The Thing Stack

comprises of three dierent technology tiers:

• Sensors,

• Microcontrollers and internet connectivity, and

• Service platforms.
