This article, examines about Internet of Things (IoT) which is another emerging innovation. Internet of Things is the interconnection of the physical articles with the internet for correspondence with one another. The physical things can share, and trade information with one another via consequently recognizing the things with their one of a kind advanced characters through IoT. This article covers the IoT engineering, favourable circumstances and disadvantages of IoT and its applications.


Internet of things has interconnectedness with our daily activities and it has created remarkable influence in this world we live in. The term “Internet of things” was introduced by Kevin Ashton in 1999. During twentieth Century, Computers lack senses, they do the things what we told them to do. With Internet of things, the Computers and other physical things can sense each other. The way of our living is changing day by day. How we drive, how we purchase things and how we get energy appliances for our house is differing from the past ways of our living. If we imagine communicating with our vehicles, electric and other home appliances, it seems like unachievable. But, with Internet of things this is possible which is surprising. Revolution in the field of IT has been made with the creation of Internet of things. IoT is understood by three different models. First is web-based model (middleware), second one is things-based model (sensors) and third is semantic based model (knowledge). The total efficiency of IoT is only known when all these models intersect each other in application area (Chandrakanth, Venkatesh, Uma Mahesh & Naganjaneyulu, 2014)

How Internet of things work?

Each physical thing has unique identity over network in Internet of things. Hence, sensors and RFID (Radio frequency identification) chips are used for sensing application fields of environment. RFID chips fundamentally assume a key job in IoT which is utilized for programmed recognizing the things with which they are associated and enable the physical articles to have interesting computerized characters which can be incorporated into the system.

Presently, question emerges how they trade such extensive amounts of data? Where they put this information and how they apply these data to the different application situations? The procedure begins when the devices discuss safely with the IoT stage which incorporates the information from a few physical devices and applies examination to share most profitable data to the applications.

IoT Architecture

With the development of IoT, this joins the computerized and physical devices together to make the keen items for making life simpler, it wound up conceivable to digitize the world. As can be found in Fig. 2 each savvy devices in IoT is empowered with RFID innovation alongside the installed sensor chips and actuators to speak with other devices.

Internet of things has the ability to detect the surrounding, making it conceivable to make brilliant application situations for worldwide level. Be that as it may, it has restricted capacity and handling ability with minimal number of vitality calculation assets which make them unsatisfactory for complex information preparing.


  1. Data: IoT provides huge information which helps us to make right decisions at right time.
  2. Time: IoT technology saves time by giving accurate and precise time information on time.
  3. Economical: IoT technology is economical depending upon the application scenarios.
  4. Tracking: IoT helps in tracking or monitoring various objects which saves time and money.

Disadvantages and limitation

  1. Security: The communication between the physical devices needs to be secure.
  2. Processing capabilities: Physical devices in IoT have limited processing capabilities.
  3. Storage capacity: The physical devices in IoT have limited storage capacities.
  4. Energy Constraints: The physical devices in IoT have limited energy resources.

Applications of IoT

There are assorted scopes of utilization in IoT which can be found in everyday lives. Industries are the most conspicuous territory of IoT applications, by this, IoT application incorporate smart home, security frameworks, smart thermostats, smart city applications, smart energy applications, smart transportation frameworks and observing of real time parking spots and so on.

Internet of Things is transforming our lives in countless ways. For example, imagine a scenario where smart traffic camera monitors the road, for traffic congestion, accidents, weather conditions etc., and communicate that status to the gateway that combines with the data obtained from other smart traffic cameras; creating an intelligent city-wide traffic system. Now this intelligent city-wide traffic system can be connected to other city-wide transportation systems which get data from their own intelligent devices creating an ever-larger system of systems.


IoT represents the future internet which opens the door for new research directions and technologies. The solution of the issues pertaining to the IoT can take this technology to the next level and make a significant contribution to the IT world. This article discusses how IoT works, challenges of IoT and application of IoT.
