The new era of computing technology

Internet of Things (IoT). Connecting everyday things with electronics, software and sensors to the internet enabling them

to collect and exchange data. Things can be anything and everything. IoT has got a great attention in each and every fields and it is an important technology. IoT provides

a way to interact with living beings, objects and machines. IoT works with the help of sensors and is combined and connected to internet. It has the ability to transfer the data over a network without human to human or human to computer interaction. IoT enables to share information about the surroundings with people, conditions of things, software system and machines. By the invention of IoT, our world is becoming smart in every aspects. As the technology grows, our world is building up smart cities, smart homes, and smart buildings. And also IoT

serves us in different ways such as transportation, waste management, irrigation facility, agriculture etc. In this paper we review a concept of IoT in all fields.


The IoT is referred to as Internet of Things. Internet of Things (IoT) the te rm

represents a conceptthat it is the ability of

network to sense, collect data around the world and sharing via internet. IoT consists of smart machines, human and even objects. IoT is becoming a relevant in every area. As we all know, we are communicating with people through the internet. Internet has impact in each and every fields such as education, business, government, society, science and technology. Our most communication way is Internet which connects people. Internet has become the most common way of communication and it came to relevant for nearly two decades. Internet is one of the most powerful creation of human history. But, now the Internet has introduced another interesting interactive way by using various things and devices. Even household appliances can also be connected to network and can enable it to work liberally. IoT in any situation is useful for real-world. IoT can be used in smart home like we can turn on the television by sitting at the place we are, we can turn on the air-condition before we are entering our home, windows can be closed automatically when the air condition is turned on, turn off the gas stove when required. All these can be done by sitting at where we are. These are some of the application in a home. There are many other purposes where IoT is applicable.

Thus IoT has ability to change including ourselves. It is a new technology of

By the IoT, cities can be improved in atmost all levels, by improving infrastructure, enhancing public transportation, reducing traffic congestion, Monitoring parking area in the city and keeping citizens safe, healthy and more engaged in the community. By connection all systems in the cities like transportation system, healthcare system, weather monitoring systems and there are also many facilities provided by the IoT technology. By the use of internet in every place, it helps to access the database of airports, railways, transportation tracking operating under specified protocols, cities will become smarter by means of the internet of things.

devices such as TVs, mobile devices, etc are usually supported by Wi -Fi. Wi-Fi have started becoming a part of the home network. Due the increasing rate of usage of mobile computing devices like smart phones, tablets, etc. The Wi-Fi and mobile devices can be used as gateways for IoT applications. The building automation with entertainment, healthcare monitoring and wireless sensor monitoring in the home and building environments. By the concept of the internet of things, homes and buildings may operate devices and objects smartly. Of the most interesting application of IoT in smart homes and buildings are smart lighting and media, air control and central heating, energy management and security.

Some of the advantages are:

Managing all of the home devices from one place.

Flexibility for new devices and appliances

Maximizing home security. Increased energy efficiency. Improved appliance functionality


The medical field has a great potential for IoT. IoT plays an from in-patient treatment to population health condition monitoring. IoT technologies in medical fields are able to automatically gather necessary information from patients and detect possible diseases in order to prevent them. Remote patient monitoring or RTM is a system that is profitable for people that have problems with the heart or diabetics. So, that patient just needs to carry the RTM device with them. So that it automatically alerts the doctor about patient deterioration. One of the best examples is the smart vaccine fridge. It is able to prevent vaccines from spoiling and monitor their conditions 24/7. There are a many ways to use IoT for optimizing everyday hospital activities and reduce costs. Lost and stolen equipment leads to spending a lot of money. The problem can be solved by integrating sensors to equipment, e.g. RFID or Bluetooth. This solution allows tracking the locations at any time. Assistance for elderly or disabled people, Monitoring

Smart Transportation:-

Technology advances are supporting the development and deployment of IoT applications in transportation.Use cases of IoT transportation are:

Connected cars

Vehicle tracking systems Public transport management Traffic management

Internet of Things can change the transport theme by transforming how transportation systems gather and make use of data. IoT is the networking of objects through embedded sensors, and other devices that gather and transmit data about real-world activities. Objects here include household appliances, mobile devices, vehicles, and structures.
