Nowadays, distributed and mobile systems are acquiring greater importance and becoming more widely used to support ubiquitous computing. However, developing systems of this kind is a difficult task. Instead of concentrating on how problems should be solved developers must worry about implementation details. Ambient Calculus is a formalism that provides primitives to describe mobile systems in an abstract way. Aspect-oriented software development and software architectures promise to achieve reusability, maintenance and adaptability, which are all essential for the development of distributed systems. In this paper, we present how a platform-independent model called Ambient-PRISMA combines both Ambient Calculus and Aspect-Oriented Software Architecture for the specification of distributed and mobile systems. A platform-specific model in .Net for supporting Ambient-PRISMA code generation is also presented.
