Self-Learn Yourself IoT in 21 Blogs – #1 – In this we will be seeing What is IoT ? Why do we need it? Significance & Impact on Modern life?
Time to Greet the New Clone that it set to rule the world !
Hello All ! Well, this is my first blog for dataottam and so henceforth I welcome your valuable feedback and that in return helps me to deliver better!
Alright, what is Internet of Things (IoT) ? How does it differ from Internet of Everything ? What is M2M ?
All the above queries would be running in your mind if you’re a beginner/newbie to this child protocol. So, the simplest answer is “They all are the same”. I will give a precise story about the emergence of IoT and inter-relationship/dependency (however, you would like to relate them) between the above mentioned terminologies.
Machine-to-Machine (M2M) is the grandfather of IoT/IoE.
Control systems made use of feedback loops to govern the state of system depending on the parameters captured during the operation. A simple example can be that of an alarm panel, safe circuitry, etc. They simply meant that any machine connected to a bus would be able to communicate with another machine connected to the same bus.
Later, as networks were born, people expanded the communication over long distances and so did the strength of connected devices. Supervisory Control and Data Acquisition (popularly known as SCADA) was the then established M2M application.
Internet, which shrunk the world, provided devices (located at remote terminals) to interact with each other in an efficient manner. This involved exchanging of useful information with human interaction. Later emerged the idea of making devices to communicate without human intervention. Researchers decided to sophisticate the human interaction with devices. So, they came up with an idea of connecting every single device irrespective of their size and volumes. This gave rise to the next-gen-tech model “Internet of Things (IoT)” and Cisco coined their own terminology “Internet of Everything (IoE)”. Though, they differ in their names, they mean and are the same.
Hopefully the above content has given some clarity on IoT. Now, we have to justify the need for IoT. Take an instance where, you need to monitor your home/child when you are away from them. A simple solution will be to fix an IP camera and monitor the same stuff using a web/mobile application. You can even hire/rent a baby-sitter. Well, the former can just give the monitoring data and the latter may not be true all the time. If you fix sensors/devices which can be reached from anywhere, you have the flexibility to monitor as well as control those devices to the best of their ability, which means your home/baby is 99.99% secure.
Note: Machines cannot be 100% fault-free
For instance, you can have separate sensors for gas, door, motion monitoring and also an IP camera. These sensors send you the useful data, based on which corresponding alarms/alerts to the local fire/police station can be raised. Well this example is for a Smart Home. Applications of IoT can be scalable across verticals like Healthcare, Industries, Asset Tracking, and Street Lighting, etc.
So, how does IoT create an impact in one’s life and prove its significance? Following issues can be solved/rectified using IoT. For instance, we can enable IP camera for 24 x 7 monitoring of your house/industry. But this results in enormous bandwidth consumption. But when integrated with proper sensors, we could trigger the video capturing at moments of danger. Apart from this, we can also replace humans at places like heat monitoring close to huge boilers, furnaces. Adding to safety financially is helps huge industrial players by Tracking of valuable assets, animals, monitoring of cellular antenna angles, etc. Entertaining/interactive features could be added to existing advertisement boards and also replacing them with Dynamically changing display boards. Management of inventories at industries, hospitals/clinics, would be a key advantage of enabling IoT in respective fields.
However, there are few people who still have an aversion towards IoT. Reasons include high installation costs, operation costs, maintenance difficulty, environmental and integration challenges, etc.
For now, I have shared my basic inputs on IoT. In the forthcoming series of Self-Learn Yourself IoT in 21 Blogs, I will explaining the protocols included as part of IoT and how to develop your unique IoT solution.
In the next blog, I will be explaining the TCP/IP stack layer-wise protocols. In the mean time, you can have a look into my thoughts on IoT and start-ups.
