Exploiting Probabilistic Trace Expressions for Decentralized Runtime Verification with Gaps

Multiagent Systems (MASs) are distributed systems composed by autonomous, reactive, proactive, heterogeneous communicating entities. In order to dynamically verify the behavior of such complex systems, a decentralized solution able to scale with the number of agents is necessary. When, for physical, infrastructural, or legal reasons, the monitor is not able to observe all the events emitted by the MAS, gaps are generated. In this paper we present a runtime verification decentralized approach to handle observation gaps in a MAS.
