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)
