1. Internet of Things

2. Introduction
Kevin Ashton coined "Internet of Things" phrase to describe a system where the Internet is connected to the physical world via ubiquitous sensors

3. What is the Internet of Things?
Internet connects all people, so it is called “the Internet of People”
IoT connects all things, so it is called “the Internet of Things”

4. Why Internet of Things Dynamic control of industry and daily life
Improve the resource utilization ratio
Better relationship between human and nature
Forming an intellectual entity by integrating
human society and physical systems

5. 5
How Ubiquitous?
Gartner: “IoT Installed Base Will Grow to 26 Billion Units By 2020.” That number might be too low.
Every sensor in every device …
in every bed, chair or bracelet ... in every home, office, building or hospital room … in every city and village ... on Earth ...
Every mobile
Every auto
Every door
Every room
Every part, on every parts list

6. Things Connected: communicated between physical world and information world

The Challenges
Every one of those sensor and control points is generating data. Often, it's very informative and very private data. Systems are needed to help those devices talk to each other, manage all that data, and enforce proper access control.

8. Big Data means BIG Challenges8
Big Data means BIG Challenges
All of the messaging, management, and access control technologies used in these large-scale device networks must be massively scalable.

9. Key Challenges for an Open Internet of Things9
Key Challenges for an Open Internet of Things
Lightweight protocols for devices to work together, communicate
Unique and extensible identifiers for all those billions of devices
Demand for API access and interoperability
Cybersecurity
Privacy and Policy

10. The Application of IoT(1)
Regional Office
Biosensor taken by people
Network
House
Equipment in public place
Application area should be divided by that two
Transportation Vehicle
Virtual Environment

11. The Application of IoT(2)
Scenario: shopping
(1) When shopping in the market, the goods will introduce themselves.
(2) When entering the doors, scanners will identify the tags on her clothing.
(3) When paying for the goods, the microchip of the credit card will communicate with checkout reader.
(4) When moving the goods, the reader will tell the staff to put a new one.

12. The Application of IoT(3)
Scenario: Health Care
Various sensors for various conditions
Example ICP sensor: Short or long term monitoring of pressure in the brain cavity
Implanted in the brain cavity and senses the increase of pressure
Sensor and associated electronics encapsulated in safe and biodegradable material
External RF reader powers the unit and receives the signal
Stability over 30 days so far

13. The Application of IoT(3)
Scenario: Health Care
National Health Information Network, Electronic Patient Record
Home care: monitoring and control
Pulse oximeters, blood glucose monitors, infusion pumps, accelerometers, …
Operating Room of the Future
Closed loop monitoring and control; multiple treatment stations, plug and play devices; robotic microsurgery
System coordination challenge
Progress in bioinformatics: gene, protein expression, systems biology, disease dynamics, control mechanisms

14. The Application of IoT(4)
Scenario: Intelligent Home
Remote monitor for smart house
Remote control for smart appliance

15. The Application of IoT(5)
Scenario: Transportation
A network of sensors set up throughout a vehicle can interact with its surroundings to provide valuable feedback on local roads, weather and traffic conditions to the car driver, enabling adaptive drive systems to respond accordingly
This may involve automatic activation of braking systems or speed control via fuel management systems. Condition and event detection sensors can activate systems to maintain driver and passenger comfort and safety through the use of airbags and seatbelt pre-tensioning
Sensors for fatigue and mood monitoring based on driving conditions, driver behaviour and facial indicators can interact
to ensure safe driving by activating warning systems
or directly controlling the vehicle

16. The Application of IoT(5)
Scenario: Transportation
In 2005, 30 – 90 processors per car
Engine control, Break system, Airbag deployment system
Windshield wiper, Door locks, Entertainment system
Cars are sensors and actuators in V2V networks
Active networked safety alerts
Autonomous navigation
Future Transportation Systems
Incorporate both single person and mass transportation vehicles, air and ground transportations.
Achieve efficiency, safety, stability using real-time control and optimization.
