Abstract

Dynamic communication systems (DCS) are complex because of their unboundedness in several dimensions. They have an unbounded and changing number of objects, a dynamically changing communication topology and unbounded message queues for asynchronous communication. We present a specification language for DCS that captures these features but is still amenable for formal verification. The verification of relevant properties of DCS is demonstrated using a combination of model-checking and abstract interpretation. Our approach is illustrated using the application domain of car platoons.
