A Framework for Checkpointing and Recovery of Hierarchical Cyber-Physical Systems. (arXiv:2205.08650v1 [cs.SY])

This paper tackles the problem of making complex resource-constrained
cyber-physical systems (CPS) resilient to sensor anomalies. In particular, we
present a framework for checkpointing and roll-forward recovery of
state-estimates in nonlinear, hierarchical CPS with anomalous sensor data. We
introduce three checkpointing paradigms for ensuring different levels of
checkpointing consistency across the hierarchy. Our framework has algorithms
implementing the consistent paradigm to perform accurate recovery in a
time-efficient manner while managing the tradeoff with system resources and
handling the interplay between …
