Behavioural equivalences over migrating processes with timers

Abstract

The temporal evolution of mobile processes is governed by independently operating local clocks and their migration timeouts. We define a formalism modelling such distributed systems allowing (maximal) parallel execution at each location. Taking into account explicit timing constraints based on migration and interprocess communication, we introduce and study a number of timed behavioural equivalences, aiming to provide theoretical underpinnings of verification methods. We also investigate relationships between such behavioural equivalences. © 2012 IFIP International Federation for Information Processing.
