2. What is IoT?

3. Evolution of IoT

4. IoT is…. (According to EU)
A global network infrastructure, linking physical and virtual objects through the exploitation of data capture and communication capabilities

5. IoT is…. (According to ITU)
A global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) things based on, existing and evolving, interoperable information and communication technologies [ITU-T Y.2060]

6. IoT is…. (According to IETF)
IoT is a world-wide network of interconnected objects uniquely addressable, based on standard communication protocols

7. IoT is…. (According to IEEE)
A network of items each embedded with sensors which are connected to the Internet.

8. IoT is…. (According to Wikipedia)
The Internet of Things (IoT) is the network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits, and reduced human exertions.

9. Machine to Machine Communication(M2M)
Data communication among the physical things which do not need human interaction.
Examples:
Data communication between things and a server.
Thing to thing communication either directly or over a network.

39. Research Need and Scope
Rapid Urbanization
6.3 Billion people to live in cities and surrounding areas by 2050
Increases pressure on city infrastructure
Makes it harder to maintain quality of life
Energy
Demands 60-70% of world’s energy
Power cuts
Emission of green house gases
Manage carbon footprint
Water resource
Consumption is around 60% of world’s water
20% results in water leak

40. Research Need and Scope
Urban traffic related
Congestion due to increase in vehicles
Creates poor traffic flow
Increases fuel consumption
Pollution
Creates a negative experience altogether
Parking problem
People looking for parking creates additional traffic congestion
Limited parking places
Waste of time and fuel to find a parking
Loss of revenue and local business

41. Research Need and Scope
Public safety
Remote monitoring of public attractions, homes, other places
Place with poor records become unattractive for citizens & businesses
In turn it slows the growth
City lighting
Problem with maintenance
Physical inspection
Lights are not intelligently operated
Intensity remains the same throughout the night

42. Research Direction…. (Simple Projects)
Smart Whether Monitoring
Smart Water Tank Monitoring
Smart Baby Monitoring
Smart Attendance
Smart Parking
Smart Health
Smart Home (Controlling Appliances)
