Overview
What is Internet of
Things(IoT)?
Where is IoT?
How IoT works?
Applications of IoT.
How Big is IoT?
Internet of Things (IoT)
 Friendly Technology.
 IoT is the network of physical objects
devices, vehicles, buildings and other items
embedded with electronics, software, sensors.,
And network connectivity that enables these
objects to collect and exchange data.
 "The Ultimate Goal of IOT is to Automate
Human Life."
Contd…
 This new wave of connectivity is going beyond
laptops and smart phones,
 It’s going towards connected cars, smart homes,
connected wearable's, smart cities and
connected healthcare.
 Internet of Objects refers to a wireless network
between objects.

Internet of Things(IOT)_Seminar_Dr.G.Rajeshkumar

  • 1. Dr.G.RajeshkumarBE.,ME.,Phd., Professor, Department of IT, Velalar College of Engineering and Technology, Erode-638 012.
  • 4. Overview What is Internet of Things(IoT)? Where is IoT? How IoT works? Applications of IoT. How Big is IoT?
  • 5. Internet of Things (IoT)  Friendly Technology.  IoT is the network of physical objects devices, vehicles, buildings and other items embedded with electronics, software, sensors., And network connectivity that enables these objects to collect and exchange data.  "The Ultimate Goal of IOT is to Automate Human Life."
  • 6. Contd…  This new wave of connectivity is going beyond laptops and smart phones,  It’s going towards connected cars, smart homes, connected wearable's, smart cities and connected healthcare.  Internet of Objects refers to a wireless network between objects.
  • 7. Contd…  Sensors act as primary devices to collect data from the environment.  Next generation devices-that can sense aspects of the real world like temperature, lighting, the presence or absence of people or objects etc., and report that real world data (or) act on it.  IoT allows objects to be sensed and controlled remotely across existing network infrastructure.
  • 9. Why You Need an IoT Gateway  First, sensors usually have very limited capabilities in terms of networking connectivity.  Sending all the information collected by sensors to a data center would be highly ineffective in terms of performance and network utilization.
  • 10. Contd…  The sensors/devices can be connected to the cloud through IoT gateway as central point where we will getting real world information from the sensors as an input to this gateway.  An IoT gateway is needed to perform the pre- processing of information, before they’re sent to the data center.  such as device connectivity, protocol translation, data filtering and processing, security, updating, management and more.
  • 13. Real World Applications of IoT 1. Smart Home if you could switch on air conditioning before reaching home • or unlock the doors to friends for temporary access even when you are not at home. • To make your life simpler and convenient. or switch off lights even after you have left home.
  • 14. 2. Wearable's  Wearable devices are installed with sensors and software's which collect data and information about the users.  These devices broadly cover fitness, health and entertainment requirements.  Highly energy efficient or ultra-low power and small sized.
  • 16. 3. Connected Cars  Most large auto makers as well as some brave startups are working on connected car solutions.  Major brands like Tesla, BMW, Apple, Google are working on bringing the next revolution in automobiles.
  • 17. 4. Industrial IoT  Smart machines are more accurate and consistent than humans in communicating through data.  Applications: a. Tracking goods, b. Real time information exchange about inventory among suppliers and retailers and c. Automated delivery will increase the supply chain efficiency.
  • 18. 5. Smart Cities  Powerful application of IoT.  Smart surveillance, automated transportation, smarter energy management systems, water distribution, urban security and environmental monitoring.  IoT will solve major problems faced by the people living in cities like pollution, traffic congestion and shortage of energy supplies etc.
  • 20. 6. IoT in agriculture(Smart farming )  With the continuous increase in world’s population, demand for food supply is extremely raised.  Governments are helping farmers to use advanced techniques and research to increase food production.  Sensing for soil moisture and nutrients, controlling water usage for plant growth and determining custom fertilizer are some simple uses of IoT.
  • 22. How Big is IoT? (IoT Market)  As of 2013, 9.1 billion IoT units  According to Gartner report, by 2020 connected devices across all technologies will reach to 20.6 billion. That’s a huge number.  Revenue growth from $1.9 trillion in 2013 to $7.1 trillion in 2020
  • 25. Plan for IoT growth:  Increased network traffic: will your firewall / IDS / IPS be compatible and keep up?  Increased demand for IP addresses both IPv4 and IPv6  Increased network complexity – should these devices be isolated or segmented?
  • 26. Threat vs. Opportunity  What happened when 50B machines become connected?  If misunderstood and misconfigured, IoT creates risk to our data, privacy, and safety  If understood and secured, IoT will enhance communications, lifestyle, and delivery of services
