A Profile-driven Environment for Modeling and Analyzing Context-Aware Software Services

Software services, in the near future, will be deployed on mobile, resource-limited devices that communicate through heterogeneous B3G (Beyond 3rd Generation) networks. They shall adapt themselves according to context and requirement changes without degrading software-related QoS. Supporting the development and maintenance of such services involves languages, methods and tools: this is the main target of the framework presented in this paper. The development process the framework refers to is a combination of multiple model-based solutions that aim at addressing these issues in a comprehensive way. In this paper, we present the development environment that we have devised to support part of such process. In particular, we show, through a case study, how to model a service-based application in the framework where each service is implemented as a collection of components and, from the obtained Service Model, how to generate and analyze a performance model in order to validate performance requirements.
