Abstract: The Internet of Things is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

I. INTRODUCTION

The term The Internet of Things (IoT) was coined by Kevin Ashton in a presentation to Proctor & Gamble in 1999. He is a co-founder of MITs Auto-ID Lab. He pioneered RFID (used in bar code detector) for the supply-chain management domain. He also started Zensi, a company that makes energy sensing and monitoring technology. The Thing in IoT can be any device with any kind of built-in- sensors with the ability to collect and transfer data over a network without manual intervention. The embedded technology in the object helps them to interact with internal states and the external environment, which in turn helps in decisions making process. The Internet of things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled "

  1. HOW DO IOT DEVICE WORKS

    An IoT system is compromised of four main components: 1.Sensors: enables the devices to collect data from the environment surrounding the device (eg. velocity, GPS coordinates, temperature, etc…).

    1. Connectivity: successively the data collected is sent to the cloud (through either WiFi or Bluetooth connection).

    2. Data Processing: once the data is received by the cloud infrastructure, it can then be processed (eg. check if the data received adhere to the requirements and if its not alert the user).

    3. User Interface: Once the data is processed, the results are then given to the and user.

    ADVANTAGES OF IOT

    Internet of things facilitates the several advantages in day-to- day life in the business sector. Some of its benefits are given below:

    1. Efficient resource utilization: If we know the functionality and the way that how each device work we definitely increase the efficient resource utilization as well as monitor natural resources.

    2. Minimize human effort: As the devices of IoT interact and communicate with each other and do lot of task for us, then they minimize the human effort.

    3. Save time: As it reduces the human effort then it definitely saves out time. Time is the primary factor which can save through IoT platform.

    4. Enhance Data Collection:

    5. Improve security: Now, if we have a system that all these things are interconnected then we can make the system more secure and efficient.

    IV.DISADVANTAGES OF IOT

    1. Privacy issues: There is always the possibility of hackers breaking into the system and stealing the data. And one might want some personal space in life. So staying connected with family and friends always giving them every detail of our life activity is not good. There is every possibility of misusing your information.

    2. Supper-reliance on technology and electronic gadgets: The younger generation has grown up with the readily available things. The internet and technology making them so non-brainy. A simple maths calculation of adding and subtracting is done through a calculator ready available in our phones. The more we entrust and dependent on the Internet, there are more chances to a potentially grievous events if we lose it.

    3. Becoming Indolent: People are more habituated to have a click based work making them lazy to any sort of physical activity, applied science in their daily routine.

    4. Unemployment: People who at lower level like unskilled labour may have high risks of losing their jobs. Security Guards, House Servants, Iron & Dry wash services etc may not have proper employment opportunities as the IoT devices replaces their work and people can work on their own.

  1. APPLICATIONS OF IOT

    1. The Smart Home: It is like making your home smart. You can control and automate the lights, room heater, ventilation, air condition, and security system by yourself. Home appliances such as washer/dryers, ovens and refrigerators can be remotely monitored and automatically get operated.

    2. Wearables: Watches along with time started giving people more data about their workouts, schedules, appointments and meetings, important days to remember Etc.

    3. The Smart Cities: The city officials interact directly with the city infrastructure management and govt department for solving real problems facing by the city citizen on each day . They can monitor what is happening in the city, how the city is evolving, and how to enable a better quality of life to their citizens. The IoT devices can solve traffic issues and reduce noise, crime, and air pollution. Having assets like local Govt departments, Security & information systems, schools, libraries, transportation systems, hospitals, power plants, water supply networks, waste management, law enforcement, and other community services.

    4. Connected Car: The vehicles are connected with the Internet can share that access with others that traveling on the same route, or another route to stay informed and safe.

    5. The Smart Home: It is like making your home smart. You can control and automate the lights, room heater, ventilation, air condition, and security system by yourself. Home appliances such as washer/dryers, ovens and refrigerators can be remotely monitored and automatically get operated.

    6. Wearables: Watches along with time started giving people more data about their workouts, schedules, appointments and meetings, important days to remember Etc.

    7. The Smart Cities: The city officials interact directly with the city infrastructure management and govt department for solving real problems facing by the city citizen on each day .

CONCLUSION

As IoT technology has already made itself comfortable in our homes, public spaces, offices and factories, and given the breakneck pace of its development, it seems that the hackneyed IoT phrase anything that can be connected will be connected is ever closer to becoming our daily reality. Therefore, the real question shouldnt be about when this will happen, but rather how the connections should be made to achieve the highest possible efficiency while retaining key features like security and cost-effectiveness. With this approach in mind, a deployment envisaging a great number of low-power, low-bandwidth devices would require the use of LwM2M, a lightweight protocol designed especially for the management of such resource-constrained machines. Therefore, seen from such practical perspective, the question of success in case of given IoT applications seems to boil down to the choice of appropriate IoT technology from the vast array of existing solution.
