  1. INTERNET OF THINGS A Revolution in the world of internet.
  2. INTRODUCTION :Smart locks, smart cars — you’ve probably heard some of these terms lately, and you’re going to hear them even more as the year goes on. But what are these things exactly — and what makes them so smart? These devices are all part of an emerging category called the Internet of Things, or IoT for short. Internet of things refers to a concept that internet is no longer just a global network for people to communicate with one another using computers, but it is a platform for devices to communicate electronically with the world around them. It includes objects ranging from computers to washing machines and laptops to microwaves. It is based on a rule that “everything that can be connected should be connected”.
  3. The Internet Of Things  The term ‘Internet of things’ was first used by Kevin Ashton in 1999.  IoT refers to the connection of everyday objects to the Internet and to one another, with the goal being to provide users with smarter, more efficient experiences.
  4. CHARACTERISTICS OF IOT 1) Interconnectivity: With regards to the IOT, all kinds of objects or devices can be interconnected so that they can share information globally. 2)Intelligence : IoT comes with the combination of algorithms and computation, software & hardware that makes it smart. In spite of all the popularity of smart technologies, intelligence in IoT is only concerned as means of interaction between devices, while user and device interaction is achieved by standard input methods and graphical user interface. 3)Heterogeneity: The devices with different architectures and platforms can be connected to each other. They can interact with other devices or service platforms through different networks.
  5. 4)Safety: As we gain benefits from the IOT, we must not forget about safety. These smart devices collect a lot of data . So, should we be worried about safety? But in this context we can say that companies are making arrangements to ensure safety of all the data collected. 5)Connectivity: Connectivity enables different devices to communicate with each other and share the collected data . For example a smart device may data collect regarding the routine of a person and may share it with another device so that it can take appropriate actions.
  6. APPLICATIONS OF IOT 1.SMART HOMES :Wouldn’t you love if you could switch on air conditioner before reaching home or switch off lights even after you have left home? Or unlock the doors to friends for temporary access even when you are not at home. Don’t be surprised. With IOT taking shape companies are building products to make your life simpler and convenient. Smart Home has become the revolutionary ladder of success in the residential spaces and it is predicted Smart homes will become as common as smartphone. All more with the help of IOT. 2.WEARABLES : Wearables have experienced a explosive demand in markets all over the world. Companies like Google, Samsung have invested heavily in building such devices. But, how do they work? Wearable devices are installed with sensors and softwares which collect data and information about the users. This data is later pre-processed to extract essential insights about user. These devices broadly cover fitness, health and entertainment requirements. The pre- requisite from internet of things technology for wearable applications is to be highly energy efficient or ultra-low power and small sized.
  7. 3. CONNECTED CARS :A connected car is a vehicle which is able to optimize it’s own operation, maintenance as well as comfort of passengers using onboard sensors and internet connectivity . For example your car could pull up your work calendar and automatically provide the best route to your meeting, or send a note to relevant parties if you’re running late. 4. SMART RETAIL :The potential of IOT in the retail sector is enormous. IOT provides an opportunity to retailers to connect with the customers to enhance the in-store experience. 5. IOT IN HEALTHCARE : Connected healthcare yet remains the sleeping giant of the Internet of Things applications. For example some hospitals have implemented smart beds which detect which bed is connected and when a patient is trying to get up. Also there are some devices that collect data regarding blood pressure, glucose etc.
  8. CHALLENGES FOR IOT There are key challenges and implications that need to be tackled before adoption of IOT can occur. 1. PRIVACY AND SECURITY : New challenges identified for privacy, trust and reliability are: A) providing trust and quality-of-information in shared information models B) Providing secure exchange of data between IOT devices C) Providing protection mechanisms for vulnerable devices. 2. DATA MANAGEMENT: Data management is a crucial aspect in the Internet of Things. When considering a world of objects interconnected and constantly exchanging all types of information, the volume of the generated data and the processes involved in the handling of those data become critical 3.INTEROPERABILITY: As devices with different platforms can communicate with each other so IoT possesses the feature of Interoperability. This makes its use convenient for the end users as they do not need to be worried about platforms.
  9. ISSUES 4.Cost versus Usability : IOT uses technology to connect physical objects to the Internet. For IOT adoption to grow, the cost of components that need to be connected needs to be relatively inexpensive . 5.Device Level Energy Issues :One of the essential challenges in IOT is how to interconnect “things” in an interoperable way while taking into account the energy constraints, knowing that the communication is the most energy consuming task on devices.
  10. CONCLUSION Internet of Things is a new revolution of the Internet & it is a key research topic for researcher in embedded, computer science & information technology area due to its very diverse area of application & heterogeneous mixture of various communications and embedded technology in its architecture . Though its mass adoption will take some time but one thing is for sure, its introduction to the world will definitely make human’s life more convenient and this world, a place worth living and loving.
