A Denotational Semantics for Dynamic Architectures
Diego Marmsoler · 2019
With the emergence of mobile and adaptive computing, dynamic architectures have become increasingly important. In such architectures, components can appear and disappear, and connections between them can change over time. Verification of such architectures is performed over the composition of its components, which is usually defined in an operational style. Sometimes however, a denotational style might be more convenient for verification. Thus, in the following paper, we propose a denotational semantics for composition in dynamic architectures based on fixed points in lattices. We show that it is well-defined by proving that fixed points are guaranteed to exist. Finally, we use our definition to derive a logical characterization of composition, which forms the basis of a framework for the interactive verification of dynamic architectures.
