A Parametric Tool for Applied Process Calculi

Abstract

High-level formalisms for concurrency are often defined as extensions of the the pi-calculus, a growing number is geared towards particular applications or computational paradigms. Psi-calculi is a parametric framework that can accommodate a wide spectrum of such calculi. It allows the definition of process calculi that extend the pi-calculus with arbitrary data, logic and logical assertions. All such psi calculi inherit machine- checked proofs of the meta-theory such as compositionality and bisimulation congruence. We present a generic tool for analysing processes from any psi calculus instance, and for implementing new instances with the help of a supporting library. The tool implements symbolic execution and bisimulation algorithms for both unicast and wireless broadcast communication. We illustrate the tool by examples from pi-calculus and the area of wireless sensor networks.
