Cyber-Physical Systems Group

Cyber-physical Systems that combine the physical world with the virtual world are starting to play an ever more important role in our daily lives. In this research group, we're looking at the fundamental concepts and challenges to realize the vision of an interconnected world. In particular, we focus on industrial communication and medical systems.


 

Making the interconnected world work in a flexible and efficient, but safe and reliable manner to the benefit of society

In contrast to human-to-human communication, communication between machines requires a fundamentally new approach. While humans are inherently able to cope with imperfections in communication, machines require predictability. This covers aspects of correctness, latency, and context sensitivity, but also new sensing paradigms.

In our group, we focus on (safety-)critical industrial applications (Industry 4.0), but also new sensing mechanisms for healthcare applications (mHealth). Solving the fundamental challenges in these areas therefore enables the Internet of Everything.

Hot Topics

  • Low-latency ultra-reliable wireless systems
    • Network design
    • Reliability enhancing strategies
    • Theoretical and practical limits
  • Systems engineering and tool development
    • Replacement of Expected Values (mean), with hard guarantees
    • Guided design
  • Mobile Devices for Healthcare (including mental health)
    • Sensing approaches and quality
    • Context recognition
    • Energy and memory efficiency
  • Localization
    • Indoor navigation and indoor positioning
    • Integrating relative and absolute positioning
    • APIs for location aware applications

Methodology and Tools

To convince industry and health care stake holders, new approaches need a solid base in theory, but–more importantly–also need validation and demonstration in practical prototypes. This leads to the following design circle.

  1. Requirements
  2. Analytical studies using abstract models
  3. Simulations and/or Verification
  4. Real-world experiments
