Cyber-Physical Systems

CPS: Breakthrough: Analysis, Identification and Mitigation of Delay Performance Bottlenecks of Network Infrastructure in Cyber-Physical Systems, supported by the National Science Foundation (NSF Award # 1646458 and # 2146968), 2018-2023

Mission-critical Cyber-Physical Systems (CPS) applications, such as industrial control and avionics systems, require their network infrastructure to provide deterministic delay performance. However, the problem of analyzing, identifying and mitigating delay performance bottlenecks in CPS remains largely unexplored due to the lack of suitable frameworks for these tasks.

Challenges, Solutions, and Software

  • Deterministic delay performance analysis for interdependent flows in CPS
    • Worst-case situation awareness of systems processing random inbound flows
    • [3][7][8-9][11-13]
  • Identification of delay performance bottlenecks
    • [4][5]
  • Mitigation of delay performance issues
    • [1][2][6][10]
  • Software and documentation
