2. “A hundred years hence people will be so
avid of every moment of life, life will be so
full of busy delight, that time-saving
inventions will be at a huge premium…”
“…It is not because we shall be hurried in
nerve-shattering anxiety, but because we
shall value at its true worth the refining and
restful influence of leisure, that we shall be
impatient of the minor tasks of every day….”

64 kilobytes of memory
operated at 0.043MHz.
An iPhone 5s has a CPU running at speeds
of up to 1.3GHz
and has 512MB to 1GB of memory
Cray-1 (1975) produced 80 million Floating
point operations per second (FLOPS)
10 years later, Cray-2 produced 1.9G FLOPS
An iPhone 5s produces 76.8 GFLOPS – nearly
a thousand times more
Cray-2 used 200-kilowatt power

5. Smart City
“A smart city uses digital technologies or information and
communication technologies (ICT) to enhance quality and
performance of urban services, to reduce costs and resource
consumption, and to engage more effectively and actively with
its citizens.” [Wikipedia]

Is this a good definition?

9. What are smart cities?
9
“An ecosystem of systems enabled by the
Internet of Things and information
communication technologies.”
“People, resources, and information coming
together, operating in an ad-hoc and/or
coordinated way to improve city operations
and everyday activities.”

10. What does makes smart cities “smart”?

11. Smart Citizens (more informed and more in control)
Smart Governance (better services and informed decisions)
Smart Environment
Providing more equality and wider reach
Context-aware and situation-aware services
Cost efficacy and supporting innovation
What does makes smart cities “smart”?

12. How do cities get smarter?

13. How do cities get smarter?
13
Continuous (near-) real-time sensing/monitoring
and data collection
Linked/integrated data
and linked/integrated services
Real-time intelligence and actionable-information
for different situations/services
Smart interaction and actuation
Creating awareness and effective participation

14. How can technology help to make
cities smarter?

15. The role of data

“The ultimate goal is transforming the raw data
to insights and actionable information and/or
creating effective representation forms for
machines and also human users, and providing
automated services.”
This usually requires data from multiple sources,
(near-) real time analytics and visualisation
and/or semantic representations.

17. What type of problems we expect to solve
using the IoT and data analytics solutions?

20. Common problems

Guildford, Surrey

22. Applications and potentials
− Analysis of thousands of traffic, pollution, weather, congestion,
public transport, waste and event sensory data to provide
better transport and city management.
− Converting smart meter readings to information that can help
prediction and balance of power consumption in a city.
− Monitoring elderly homes, personal and public healthcare
applications.
− Event and incident analysis and prediction using (near) real-
time data collected by citizen and device sensors.
− Turning social media data (e.g.Tweets) related to city issues
into event and sentiment analysis.
− Any many more…

35. In conclusion
−Smart cities are made of informed citizens, smart
environments and informed and intelligent decision
making and governance.
−Smart cities should promote innovation, equality and
wider reach of services to all citizens.
−IoT plays a key role in making cities smarter;
openness of data and interconnection and
interoperability between different data sources and
services is a key requirement.
−Technology alone won’t make cities smart.
