INTERNET OF THINGS

• Dr.K.THIRUGNANASAMBANTHAN, Asst.Professor, SIMS

The Internet of things (IoT) defines the network of physical objects “things” that are implanted with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. A thing in the IOT can be a person with a farm animal, a heart monitor implant with a biochip transponder.  IOT organizational applications are in medical and healthcare (IOMT), transportation, v2x communication, Home automation etc.  IOT is also used in various fields like manufacturing, agriculture, infrastructure, environmental monitoring, Military applications (IOBT) etc.

Characteristics of IOT:

1) Dynamic & Self Adapting: IoT devices and systems may have the competence to dynamically alter with the changing contexts and take actions based on their operating circumstances, user‘s context or sensed atmosphere.

 2) Self Configuring: allowing a huge number of devices to work together to provide certain functionality.

3) Inter Operable Communication Protocols: support a number of interoperable statement protocols and can interconnect with other devices and also with infrastructure.

4) Unique Identity: Each IOT device has a exceptional identity and a sole identifier (IP address).

5) Integrated into Information Network: that allow them to communicate and altercation data with other devices and systems.

IoT is not distinct from the Internet, but an extension of it – a way of intelligently blending the real and cyber worlds. By 2050, there will be 24 billion interconnected devices such as thermostats, electric meters, streetlights, fitness trackers, water pumps, cars, elevators etc.  These IoT-enabled devices contain sensors that continuously collect and respond to data, and this vast level of data can be used to unlock new levels of astuteness.
