Formalization of Mobile UML Statechart Diagrams Using the π-calculus: An Approach for Modeling and Analysis

Mobile UML (M-UML) has been proposed as an extension of UML to model mobile agent-based software systems. As UML, M-UML suffers from lack of semantics due to its semi-formal structure. Formal methods have been used largely in order to deal with such problems. π-calculus is one of these formal methods that deal with mobile computation. In this paper, we propose a formalization of M-UML statechart diagrams using π-calculus in order to provide a formal semantics for such diagrams. The generated π-calculus specifications are then used to analyze and check systems using π-calculus analytical tools (e.g. MWB tool). We illustrate our approach by an example.
