Multi-agent approach for resilience enhancement in wireless sensor and actuator networks

Recent advances on networked devices, with different communication structures and capabilities, are reshaping the network communications-based supervision, while raising new challenges. In particular, as a result of the integration of control systems with state of the art information technologies, new uncertainties, not only from the tangible physical world, but also from a cyber-space perspective, are brought into play. One of the most vulnerable components of these systems is the wireless nodes, which can have a major impact on the overall systems' performance. This paper focus on the development of a hierarchical multi-agent framework for resilience enhancement over wireless sensor and actuator networks. Experimental results collected from a laboratory IPv6 based test-bed comprising distributed computational devices and heterogeneous communications, show unequivocally the relevance and inherent benefits of the proposed approach.
