Smart living, another name for the Internet of Things where everyone and everything is connected to the internet. 

With the internet being a revolutionary invention, IoT is emerging as a ubiquitous computing network. IoT is going to transform our way of living by making our homes, industries, cities and the environment smart.

According to Cisco, over 50 million devices are expected to be connected to IoT by 2020.

Significant areas of IoT applications are:

Smart Homes

In a smart home, your routine will be supported by Smart Things. With your wake up alarm, smart things will turn on/off the lights, thermostat, radio or coffee machine. While you leave for work, your doors will be locked automatically and a security camera will be turned on. If there is any problem in your absence, you'll even get an alert. 

When you return, your garage will be automatically opened, radio tuned to your favourite channel and smart home appliances will be active.  

Factories and Manufacturing

The smart industries are termed as a fourth-generation industry. The industry 4.0 concept is based on machine to machine (M to M) communications. Workers safety, environmental protection by controlled emissions are some merits of introducing IoT in manufacturing processes. 

Even the supply chain management is going to change the way it used to work. Now tracking is very convenient. Products which need specific environmental conditions (temperature, humidity) could be saved from damaging as any change in required conditions will create an alert.


Environment monitoring has a wide scope of IoT. It is useful in weather forecasting, water safety, waste management, commercial farming etc. In case of natural disaster, IoT could help in covering a larger area of a network, rescue announcement, emergency networking with hospitals and police stations. 

"What can be gained by directly connecting products to the internet that cannot already be attained with the current range of gadgets and contraptions? What are the consequences and critical issues of a transition to a connected world? Are firms obligated to incorporate another feature into their products'  just because or is there an actual rationale somewhere behind the hype?" (Business Horizons, volume 60, issue 5)

Above are obvious questions arising in the minds of people who are uncertain about the IoT's successful implementation in future.

Well, like many other technologies we'll be using it without actually realizing when and how we get connected to IoT.
It is wiser to say that everything could be connected to the internet soon rather than assuming everything will be connected to the internet in future. Many systems are getting redesigned to support more advanced IoT devices.

The European Commission, countries such as China and various multinationals are on the peak of doing various researches in IoT. Till 2020 we'll probably be able to see advancements such as large scale wireless sensor network, deploy and forget system, smart grid household metering and much more.

By 2025 and after we may have smart traffic, intelligent transport and logistics, autonomous vehicles and many things which we dream of. 


With every new technology, new challenges keep on arising and hence solving them gives rise to a more developed and fault-free advanced version. Scalability, data volume, data interpretation, interoperability, power supply, security and privacy are some of the significant challenges foreseen in IoT. 

"The charismatic and pleasing aspects of IoT can be envisioned in reality only if a `well-defined' standard can be constituted that could deal with the complexity, size, security, privacy, time, cost, peaceful co-existence and better integration among the things/objects, and the socio-economic implications." (Pradeep Kumar, Future Internet and Internet of things).

Since now benefits of IoT have been found significant in almost every field. Soon the Internet of Everything will be a household reality.
