A testbed to simulate and analyze resilient cyber-physical systems

This paper describes a testbed for development, deployment, testing, and analysis of Cyber-Physical Systems (CPS) applications. The testbed incorporates smart network hardware, allowing high-fidelity emulation of CPS network characteristics, and CPS simulation environments to enable high-frequency sensor reading, actuator control and physical environmental changes. We discuss the architecture of this testbed and present the types of experiments and applications which can be run to study hardware and software fault tolerance, software reconfiguration, and system stability characteristics in distributed real-time embedded systems. We also describe the scalability, limitations, and potential extensions to this testbed.
