2. Etymology
• Emerged around 2006, coined by Helen Gill at National Science
foundation in the United States.
• Cyberphysical Systems => integration of computation with physical
processes.
• CPS is about the intersection, not union, of physical systems and the
cyber.

3. Cyberphysical Systems and IoT

4. Buzz Words
• Cyberphysical systems(CPS)
• Internet of Things (IoT)
• Internet of Everything
• Industry 4.0
• Machine to Machine (M2M)
• The Fog (like the cloud)
• Tsensors (Trillion Sensors)
• Smart Planet

5. CPS Structure
Computing + Networking forms the crux of CPS

6. CPS Structure

7. Applications of CPS

8. Examples
• Traffic lights and cars co-operate to ensure smooth traffic flow
• Smart-dust : Tiny embedded systems network, used for monitoring
pollution levels in a city
• Co-ordinated drones ! A network of drones and bots for surveillance

9. Emerging IoT / Cyberphysical systems

10. Buzz in business!
• Gartner reports that by 2020, we will have 50 billion connected
devices.
• $14 trillion industry by 2022
• India has a potential of generating $12 billion revenue
• VLSI-MEMS industry, Networking companies, Big Data and analytics
companies to drive innovation

11. Key challenges for CPS
• Precision
• Adaptability and scalability
• Security & Privacy

12. CPS design challenges

13. CPS in academia
• Centre for Hybrid and Embedded Software Systems (CHESS) is driving
academic research in the area of CPS
• Modelling physical systems and developing framework for distributed
real-time systems
• Ex : TerraSwarm technologies , PTIDES OS, Ptolemy II framework etc.
