Abstract

We study dynamic networks of infinite-state timed processes, modelled as unbounded Petri nets. These processes can evolve autono-mously, synchronize with each other (e.g., in order to gain access to some shared resources) and be created or become garbage dynamically. We introduce dense time in two different ways. First, we consider that each token in each process carries a real valued clock. We prove that this model can faithfully simulate Turing-complete formalisms and, in particular, safety properties are undecidable for them. Second, we consider locally-timed processes, where each process carries a single real valued clock. For them, we prove decidability of safety properties by a non-trivial instantiation of the framework of Well-Structured Transition Systems.
