Architecture Description for Mobile Distributed Systems

In this paper we motivate an Architecture Description Language (ADL) for mobile distributed systems based on the π-calculus. Different from other approaches, the non-functional properties, which are essential when mobile architectures are described, are treated in a flexible manner by inserting logical formulae for expressing and checking non-functional properties into π-calculus processes. A formal example is given to illustrate the approach before the constituents of the ADL are sketched

Modellierung und Analyse mobiler Architekturen

Das Verhalten eines mobilen Systems wird bestimmt durch seine Architektur (statische und dynamische Anteile, Softwareverteilung), die zu Grunde liegende Netzwerkinfrastruktur (Topologie, Parameter wie Bandbreiten oder Latenzzeiten) und Interaktionen der Benutzer mit dem System. Um bereits zur Entwurfszeit zu bestimmen, ob ein mobiles System nichtfunktionale Anforderungen wie Antwortzeiten oder Verfügbarkeit von Diensten erfüllt, kann eine Simulation des Systems auf Basis eines Architekturmodells unter Einbeziehung eines Netzwerk- und eines Benutzerinteraktionsmodells durchgeführt werden. Ein derartiger Ansatz unter Verwendung der Architekturbeschreibungssprache Con Moto wird in diesem Beitrag vorgestellt

AMBIENT-PRISMA: Distribution and Mobility in Aspect-Oriented Software Architectures

This thesis presents a framework called Ambient-PRISMA for describing and developing distributed and mobile software systems in an abstract way. Ambient-PRISMA enriches an aspect-oriented software architecture approach called PRISMA with concepts of Ambient Calculus (AC). Ambient Calculus (AC) is a formalism that provides primitives to describe distribution and mobility characteristics in an abstract way. It introduces a concept called ambient which is a bounded place where computation happens. This enrichment is performed by extending the PRISMA metamodel, and Aspect-Oriented Architecture Description Language (AOADL). A case study of an electronic Auction System with mobile agents is used throughout the thesis in order to illustrate the work.Ali Irshaid, N. (2007).
