Abstract

After introducing the timed distributed pi-calculus, we developed a formalism (called TiMo) bridging the gap between the existing process calculi and forthcoming realistic languages for multi-agent systems involving explicit locations, local clocks, as well as timed migration and interaction. Several variants of TiMo were developed during the last years: a probabilistic extension pTiMo, a real-time version rTiMo, TiMo with access permissions. Interesting properties of distributed systems described by TiMo refer to various time constraints over process migration and communication, bounded liveness and optimal reachability. A verification tool was developed by using an extensible platform for model checkers. A formal relationship between rTiMo and timed automata allows the use of model checking capabilities provided by UPPAAL.
