What is IoT:
In the most simple terms, it is a connection of everything to the Internet or machine-to-machine communication. For example: 1) If you are driving a car and you got late somehow then the car will itself message to the other party about your presence. 2) You can set an alarm in your mobile such that it will notify to your tea machine as soon as you wake up. So imagine if your refrigerator telling you about its wear and tear or your tea machine is asking for more sugar by itself. It’s pretty much like IRON MAN life ;).
Why we need it:
Humans have very limited time, energy, accuracy and memory as compared to Computers. Moreover, most of us don’t want to waste our time in doing unimportant tasks. So IoT will make our devices interconnected so that one could guide another with minimal human interaction. We will reduce waste, loss and cost would be able to know when things needed replacing, repairing or recalling and whether they are fresh or past their best.
Now let us give you a very practical and real example. In 2009 Kota Chambal Bridge, Rajasthan was collapsed, killing many people, because steel rods were inadequate to handle to pressure. Now in the world of IoT, we can use smart rods that can tell us about its wear and tear or sensors equipped in cement to monitor stresses or cracks. It will alert us before a catastrophe. IoT is not limited to only technological advancements but it can even help drivers driving towards the bridge. These rods will detect it and communicate info. to the driver via wireless internet in one’s car. Once car knows there’s a hazard ahead, it will instruct the driver to slow down, and if the driver doesn’t, then the car will slow down for him.
How is it possible:
It is actually possible through the IPV6 address. According to Steve Leibson, we can assign an IPV6 address to every atom on the surface of the earth, and still have enough addresses left to do another 100+ earths.” In simple words, we can easily assign an IP address to every “thing” on the planet. So when we can assign an IP address to almost everything then we can easily connect them to the Internet. Right?
Security is one the biggest issue. When billions of device are connected together, anyone who has access to your tea machine will have access to your entire network. Now imagine what possibly he could do with it. Especially hackers could drive you crazy.
Another major concern is data storage. With petabytes (a petabyte is 1,024 terabytes) of data that all these devices going to produce will need storage and tracking. This massive storage needs new innovative techniques of data handling.
We don’t really know what more opportunities and challenges are going to be as more and more devices join IoT. The best thing that we can do right now is to grab more information about IoT and how it could impact human race.
