Easy to understand. All basic concept will cleared about Big Data and Smart Cities.

3.  Big data
 Background of big data
 Introduction to Smart cities
 Challenges cities face today
 Vision of smarter cities
 Sensor technology

4. What is big data
Big Data is a massive volume of structured and unstructured
data so large it's difficult to process using traditional database
or software techniques.
Big data is being generated by everything around us at all
times. Every digital process and social media exchange
produces it.
Big Data and the Internet of Things (IoT) have a significant
role to play in making our lives simpler by inter-connecting
our scattered digital footprints to create an
efficient and cohesive habitable unit for us.

7. How to make a city smart:
Big Data and the Internet of Things are the fundamentals of
creating a connected city. There’s data everywhere due to the
presence of smart devices.
A city “connecting the physical
infrastructure, the IT infrastructure,
the social infrastructure, and the business infrastructure
to leverage the collective intelligence of the city”

8. Vision of smarter cities
 Environmental sustainability and efficiency
 Sustainable homes and buildings
 Efficient use of resources
 Efficient and sustainable transportation
 Better urban planning - livable cities

9. Real time information on transport, population and waste
No traffic Congestion
Access to energy-saving resources
Clean and fresh air
Water shortage or power outages

10. The sensors attached to everyday objects, permanent fixtures
or furniture around a city can receive and transmit data, track
the presence of vehicular and people
movement, and this data can be used
to optimize energy, plan deliveries, and
have a regulated movement around the city.

11.  Smart parking
 Structural health
 Noise Urban maps
 Smartphone detection
 Electromagnetic field levels
 Traffic congestion
 Smart lighting
 Waste management
 Smart roads

12. Targeted towards mobile class
Risk of data privacy and security threats
Uncertainty in cost effectiveness
