Paper: On the Verification of Broadcast Protocols (at LICS 1999)

Authors: Javier Esparza Alain Finkel Richard Mayr


We analyze the model-checking problems for safety and liveness properties in parameterized broadcast protocols, a model introduced in [Emerson,Namjoshi, LICS'98]. We show that the procedure suggested in [Emerson,Namjoshi, LICS'98] for safety properties may not terminate, whereas termination is guaranteed for the procedure of [Abdulla, Cerans, Jonnson, Tsay, LICS'96] based on upward closed sets. We show that the model-checking problem for liveness properties is undecidable. In fact, even the problem of deciding if a broadcast protocol may exhibit an infinite behavior is undecidable.
