Internet of Things literally means an interconnected network of machines.
We are talking about our day to day machines communicating to each other. Imagine your alarm clock informing your coffee maker and toaster about the time when you’ll be awake and by the time you wake, your coffee and toast is ready.
Consider another scenario when your car receives a message from the traffic signals that there is an accident on your usual route to office and your car takes an alternative route saving you from getting late for that important client meeting.
Do you find these things imaginary? Well the technology is very close to offer this to us. Technology has covered a long distance after the first internet connected toaster was presented at a conference in 1989.
The Internet of Things (IoT) is the network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment. – Gartner
Is this real?
When the first computer was invented back in 1940s, no one could imagine that few decades later, doing business without a computer will become impossible. If you travel back in time and try to make someone in that era understand this, he would laugh at you. Same is the case of IoT currently. It is Hard to believe but is the truth of tomorrow.
DNA of IoT
This internetwork of devices called internet of things is comprised of three important aspects: Device, Network and Application which is also known as DNA of IoT.
What takes a device to become the ‘thing’ in ‘Internet of things’. First it should generate some sensory data like temperature, pressure, etc. it should have a unique identification so that it can be identified while communicating. It should have networking ability i.e. to get connected to a network.
A network becomes part of the IoT if it can provide unique identification to these devices. It has some IoT gateway access. It has a front end or an app or a controlling device where user interface is available. The cloud networks are the key to this kind of an environment.
As the devices in the IoT gather various sensory data and send it to the controlling application through network, it analyses the date and helps you take a decision or at times decides itself and instructs you what to do next. Cloud computing applications are the key to leveraging in an environment where data from various sources is to be analysed anytime anywhere.
Is it safe ?
Though IoT is the next big thing in the technology industry, the technologists are still debating over the kind of challenges it would raise against the security of the Data. Also since this is in nascent stages, there is no single underlying communication protocol decided
Market Drivers & Barriers
Expanded Internet connectivity
High mobile adaption
Low cost sensors
Large IoT Investments
Smart Homes: This is one of the most discussed applications of IoT. Basically, if you can connect every appliance in your house to the internet, you can remotely manage it.
Infrastructure management like traffic control, water supply, etc
Industrial Applications: Resource allocation, asset management, supply chain can be fully automated and reduce the people working in manufacturing plant.
Energy and Power sector: Power production, distribution and power saving can be improved considerably with IoT
Environment management: Disaster management with Anticipation of calamities, etc
Community Health-care: The remote monitoring of the patient can be extremely useful in regions where super-specialty hospitals are not there.
Defense: Drones are the weapon of today and military robots will rule the military of future.
Agriculture: Sensors in the soil to detect acidity levels, temperature and other variables
Logistics: sensors with the packages will help avoid loss of parcels
Hospitality: Next generation locks, room controlled devices, connected TVs and beacons
After the advent of internet, IoT is perhaps the next biggest thing happening in the world of technology. It is considered as the disruptive technology that will change the way we live today.
