In the present world, we all know about the importance of
internet. In today’s world, Internet helps us in daily life work like
communication, messages on mail, video conferencing and many applications that
runs on internet. In internet mainly as of now computers, mobiles and some
other computing devices are interconnected. Day by day people demand advanced
level of services to the society and to the business that growing the size of internet work.
Currently the size of connected device in network is large
but it is going to be extra-large in near future. As of now 9 million things
are connected to internet but in future this no. may cross 20 billion. Can you
guess why? The answer is IoT (Internet of things). Now the question is what is
IOT?
IoT stands for “Internet
of things” gives us the feeling of something that is connected with the internet.
IoT is a network of physical objects that can communicate with each other or
with the human. The objects are embedded with the sensors, processors and communication
technology so that they will be able to sense the command and communicate in
the network. It is going to interconnect different physical objects that we see
around us, the different objects such as the lighting system in a room, the
fans, the air conditioners, water pump, the microwave oven and the refrigerator,
not only in our homes, but also in our businesses such as internet working
different machines.
In IoT, devices communicate wirelessly
so the communication medium should be wireless. It cannot be wired because devices may also movable. Some wireless protocol are RFID (Radio frequency communication), Bluetooth
Zeebee, Wi-Fi cellular technology and others. The Coming 5G network technology
will also give boost to the IoTs.
Human can centrally control all
devices through the system that can interact with the other objects.
There is M2M (Machine to Machine)
interaction that means one machine can give or take instruction or human can
interact with the machine. That gives the concept of smart home or smart cities.
For example—suppose in hot summer days you are coming to your home and opens
the door. As soon as you open the door, Air Conditioner (AC) will be on. In
Smart home all the home appliances are smartly active or passive on the base of
requirement and time. That saves the power and improves the efficiency.
IoT Applications:
- In business/manufacturing sector for different machine interaction in assembly line Production
- In Healthcare for recording keeping and remotely monitoring health of patient.
- In Agriculture, like irrigation of field, and food supply chain.
- Home and office.
- Infrastructure monitoring and safety
- Weather Monitoring.
