Internet of things IOT

The IOT is an environment in which objects, devices, vehicles, buildings and other items which are deeply merged with electronics, software, sensors and network connectivity, which enables these objects to collect and exchange the data from one thing to another thing. This network allows the objects to be sensed and controlled automatically across the existing infrastructure .This network creates the opportunities to integrate the things into computer based network system for improving the efficiency, accuracy, and economic benefits. When it is augmented with sensors and actuator then this technology becomes cyber-physical systems. Smart grids, smart homes and intelligent transportations are examples of  the internet of things.

HISTORY OF IOT

The concept of internet of things was developed in 2013, because of the convergence of multiple technologies, whose range from wireless communication to the internet and embedded system to electromechanical system .its means that wireless sensor network, control system and automation are involved to enable the IOT. The smart devices concept was discussed in 1982, with a modified coke machine at Carnegie Mellon University. This was the first internet connected appliance. Between 1993 and 1996 several companies proposed a  solution like Microsoft’s at work or Novell’s Nest. The IOT was became popular first time in 1999, through the Auto-ID center at MIT and other concerned market analysis publications.

 STRUCTURE & WORKING OF IOT

The structure of IOT composed of three layers, sensing layer, network layer and application layer, which has been vastly accepted in the industry.The sensing layer mainly realize physical information collection, automobile identification and intelligent control. Since objects do not have capabilities to communicate with each other they are communicate through sensing layer. The network layer includes various kind of wireless or cables gateway and access network .The main work of this layer is to realize the two-way transmission, routine, and control between sensing layer data and application layer. The application layer provides support between sub layer and various kinds of Practical IOT applications

DIFFERENT STRUCTURES OF IOT:




There are different type of IOT structures are used in industry, some of which are.

  • Automatic identification and data capture (AIDC) including sensors and sensors networks.
  • Communication structures and networks
  • Computer data and information processing and storage structure
  • The whole infrastructure that is internet including applications layering, texting and emailing.
  • Cloud, computing infrastructure and services support

WHY IOT HAS A SO MUCH IMPORTANCE IN CLOUD COMPUTING

In the internet of things cloud computing is so much important because it acts as a front end to access the internet of things .Cloud computing is now more popularservice that comes with more advantages and characteristics. Actually, cloud computing is based on the user,the user do his duty entirely through the internet. Nowadays the internet of things gives the hope for human life activity. If the worker needs to finish his work and submit the repot to the manager then he/she just use the computer memory space .There is no problem if the computer is connected to internet. He/she can use the cloud computing services to finish theirs works because the data is controlled by the server ,so the IOT is so much important in cloud computing.

DIFFERENCE BETWEEN IOT AND CLOUD COMPUTING

The internet of thing and cloud computing two are very different technologies but both are very important in our daily life. The internet of thing is based on intelligent and self-configuring things interconnected in a dynamic and global network infrastructure.it represents the one of the most disruptive technology. IOT is generalized used on small things with limited storage and processing capacity but there are some issues on privacy, security and reliability. Cloud computing has virtually unlimited capabilities in term of storage and processing power. It is much more mature technology and more of the issues of IOT is partially solved through cloud computing. IT is new technology in which these two technologies are merged together.

APPLICATION OF IOT

Environmental monitoring:  It is used in environmental monitoring, use sensors to assist in environmental protection by monitoring air or water quality.

Infrastructure management:It is used in monitoring and controlling the bridges, railway tracks, off and on shore wind farms.

Manufacturing: It is used in control of network, management of manufacturing equipment and situation management.

Energy management: It is used to control the energy consumption in energy management system .it is combined used in all forms of energy consuming devices (switches, power outlets, bulbs, televisions etc.)

Medical and health care systems: IOT devices can be used to enable the remote health monitoring devices and emergency notification systems. The health monitoring devices can range from blood pressure and health rate monitor.

ADVANTAGES OF INTERNET OF THINGS

There are several advantages of internet of things but the six major advantages are.

  1. Tracking behavior for real-time marketing.
  2. Enhanced situation awareness.
  3. Sensor driven decision analytic.
  4.  Process optimization.
  5.  Optimized resources consumption.
  6. Instantaneous control and response in complex autonomous systems.

DISADVANTAGES OF IOT

The disadvantage of internet of things is the breach of privacy when anyone put on anything on internet then it will always be there. There is no protection for save the data from hackers any one can search the data and use.The reliance on technology is another argument against IOT. As time has passed our generation has grown up with readily availability of internet technology in general. However relaying on technology on day to day basic, making decision by information that gives up could lead to devastation.
