Unbounded creation and destruction of objects and a dynam-ically evolving communication topology are characteristic features. Promi-nent examples include traffic control systems based on wireless communi-cation and ad hoc networks. As dynamic communication systems have tomeet safety-critical requirements, this thesis develops appropriate specifica-tion and verification techniques for them. It is shown that earlier attemptsat doing so have failed.Partner graph grammars are presented as an adequate specification for-malism for dynamic communication systems.
