A Distributed Multi-Agent Framework for Resilience Enhancement in Cyber-Physical Systems
Cyber-physical systems (CPSs) are nowadays an important component of most industrial
infrastructures and materialize the integration of control systems with advanced information technologies.
Commonly, they aggregate distinct communication platforms and networked devices or nodes with different
capabilities and goals. The resulting increase in complexity has inevitably brought into playing new
challenges, namely, on the physical world and cyber space. In these systems, the development and gaining of
state awareness and how to deal with the inherent vulnerabilities of the overall system are essential and also
challenging. In this paper, the problem of resilience enhancement in CPSs is addressed based on a hierarchical
multi-agent framework that is implemented over a distributed middleware, in which each agent carries out
specific tasks. Physical and cyber vulnerabilities are taken into account, and state and context awarenesses of
the whole system are targeted. The proposed framework ensures a minimum level of acceptable performance
in case of physical disturbances and malicious attacks, as demonstrated by experiments on an IPv6-based
test-bed
