Internet of things or IoT is the network of physical devices, which are connected by different communication protocols and this can be controlled over the internet, Individual elements in these networks are called ‘things’. Mobile phone and other device are already connected with internet ‘things’ refer to the devices like a thermostat, A>C and coffee maker etc. which yet to connect to the internet. lets take a small example to discuss IoT, I’m leaving from my office at 6 pm, there is 20mins driving to my apartment, when I leave the office GPS in my phone share my location information with device in my apartment, so they will guess I will arrive in a 30 mins or something, then my A.C set room temperature to optimum, coffee maker will start to make a coffee which is still hot when I arrive at doorstep. IoT not only enables these devices to control over the internet but also establish a device to device communication. It is important not to get confused with M2M communication in which homogenous machine form a network to establish communication to increase efficiency, in IoT, it is the network of the heterogeneous system doing completely different functions, all this function will be monitored, processed and controlled by a cloud server, which 24/7 connected with the devices.
IoT has its application in various fields like industrial, Energy transmission, weather monitoring, pollution control, Traffic control, heal monitoring, home appliances etc. Industrial expert is saying by 2020 there will be 50 billion functional IoT devices.
1. Smart home
Smart Home clearly stands out, ranking as the highest Internet of Things application on all measured channels. More than 60,000 people currently search for the term “Smart Home” each month. This is not a surprise. The IoT Analytics company database for Smart Home includes 256 companies and startups. More companies are active in the smart home than any other application in the field of IoT. The total amount of funding for Smart Home startups currently exceeds $2.5bn. This list includes prominent startup names such as Nest or AlertMe as well as a number of multinational corporations like Philips, Haier, or Belkin.
There are plenty of wearable innovations to be released: like the Sony Smart B Trainer, the Myo gesture control, or LookSee bracelet. Of all the IoT startups, wearables maker Jawbone is probably the one with the biggest funding to date. It stands at more than half a billion dollars.
3. Smart City
The smart city spans a wide variety of use cases, from traffic management to water distribution, to waste management, urban security, and environmental monitoring. Its popularity is fueled by the fact that many Smart City solutions promise to alleviate the real pains of people living in cities these days. IoT solutions in the area of Smart City solve traffic congestion problems, reduce noise and pollution and help make cities safer.
4. Smart Grids
Smart grids are a special one. A future smart grid promises to use information about the behaviors of electricity suppliers and consumers in an automated fashion to improve the efficiency, reliability, and economics of electricity. 41,000 monthly Google searches highlight the concept’s popularity. However, the lack of tweets (Just 100 per month) shows that people don’t have much to say about it.
5. Industrial internet
The industrial internet is also one of the special Internet of Things applications. While many market types of research such as Gartner or Cisco see the industrial internet as the IoT concept with the highest overall potential, its popularity currently doesn’t reach the masses like smart home or wearables do. The industrial internet, however, has a lot going for it. The industrial internet gets the biggest push of people on Twitter (~1,700 tweets per month) compared to other non-consumer-oriented IoT concepts.
