This document discusses Internet of Things (IoT) and smart cities. It defines IoT as interconnected devices that can communicate with each other to achieve common goals. It also defines smart cities as using information and communication technologies to integrate core systems and respond intelligently to various needs. The document outlines technologies used in IoT like RFID and sensors. It describes smart city components like smart communities, smart homes and smart grids. It discusses challenges of IoT like security and privacy and of smart cities like investment and interoperability. It concludes that IoT and smart cities are related areas with opportunities for innovation but also challenges to address.

9. Smart Cities

10. Smart City - O que é?
"The next generation information technology to
all walks of life..." - Samuel Palmisano – IBM, 2009
(SU; LI; FU, 2011)
"Smart city as the use of information and communication
technology to sense, analyze and integrate the key
information of core systems in running cities. At the same
time, smart city can make intelligent response to different
kinds of needs, including daily livelihood, environmental
protection, public safety and city services, industrial and
commercial activities."
(QIN; LI; ZHAO, 2010)

11. Smat City - O que é?
"A Smart City provides ubiquitous connectivity, future-proof
broadband capacity and total wireless fidelity,
with IP-enabled devices communicating and being
managed through a control center, allowing tenants,
residents, and visitors’ real-time access to key
information about their environment from anywhere."
(International Data Corporation)
(PAN et al,2011)

12. Smart, porém simples
"Cities must use new technologies to transform their
systems to optimize the use of finite resources. The
topics of the optimization include Transportation,
Public Safety, Energy/Utilities, Healthcare, Education,
and Developments."
(IBM)
(PAN et al,2011)

13. Quão smart?
• Smart Environment
• Smart Business
• Smart Citizens
• Smart Government
(PAN et al, 2011)

14. Arquitetura

and Xuemin (Sherman) Shen. Smart
Community: An Internet of Things
Application. The Internet of Things.
IEEE 2011.

16. Smart Homes
"[A building with implemented passive energy efficiency
measures], [central computer operated infrastructure
systems], [networked appliances, advanced energy
management and renewable energy sources]."
(LUGARIC; KRAJCAR; SIMIC, 2010)

17. Composição de Smart homes
• Sensores
• Atuadores
• Controladores
• Unidade Central
• Interface
• Rede
• Medição inteligente
(LUGARIC; KRAJCAR; SIMIC, 2010)

18. Smart Grids
"...integration of actions of generators, transmission
and distribution system operators, monitoring and
control centers, suppliers and consumers through
exchange of information in real time."
(LUGARIC; KRAJCAR; SIMIC, 2010)

19. Esquema Smart Grids
LUGARIC; KRAJCAR; SIMIC, Smart City - Platform for Emergent Phenomena Power System Testbed Simulator, IEEE

20. A tecnologia envolvida
"Modem systems will have to act more anticipatory:
weather forecasts, room bookings, energy prices
and other aspects that can - certain error probabilities
assumed - be predicted will be used for both increasing
comfort and efficiency."
(BACH; WILHELMER; PALENSKI, 2010)

21. Desafios
• Investimento em sensores e formas de
atuadores;
• Interoperabilidade:
o Dispositivos;
o Serviços;
• Processamento;
• Controle de privacidade;
• Mobilidade;
(Haubensak, 2011)

22. IoT e Smart Cities
• IoT contribui para a implementação de
Smart Cities;
• "Internet das Coisas + Internet = Cidade
inteligente" (Kehua, 2011);

23. Conclusão
• Duas áreas relacionadas e promissoras;
• Oportunidade de inovação e criação de
novos negócios;
• Muitos desafios -> Ainda poucas
soluções amplamente aceitas;
• Algumas barreiras:
o Investimento;
o Quebra de paradigmas;
