Model-driven development of component-based adaptive distributed applications

Abstract

This paper introduces an approach to develop componentbased adaptive distributed applications. Our approach separates the communication and the functional aspects of a distributed application and specifies the communication part as an abstract distributed component called the communication component. We then introduce a model-based process for automatically building many evolutionary variants of this component at deployment level, and integrating these variants into the target adaptive application that can dynamically select the running variant in order to adapt to the changing context. Thanks to an adaptation guide generated by the process, the adaptive application can coordinate distributed adaptations to (1) consistently transfer data of the replaced variant to the new one and (2) maintain the architectural coherence between distributed parts of the application. Hence, the target adaptive application can correctly adapt at runtime without loss of data. In this paper, we present the principle of our approach, illustrate it with an example, and show how we have automated the development process by model transformations.

A Process Model for Component-Based Model-Driven Software Development

“…These reusable specifications can be tailored for a specific design, executed and validated in a simulation environment, and transformed into the real system. Phung-Khac et al [30] present an approach to develop component-based adaptive distributed applications by using model transformations to build evolutionary variants of the components at deployment level. The authors separate the communication and the functional aspects of a distributed application, and try to automate the development process.…”

MOCAS: A State-Based Component Model for Self-Adaptation

“…Certains composants sont ainsi dédiésà des services non-fonctionnels liésà l'adaptation. Par exemple, Phung-Khac et al [36] Sur le même principe, Egyed et Wile [116] laissent une instance de composant directement instancier les composants dont elle a besoin. Le comportement d'un composant est décrit avec une machineàétats.…”

Issues in applying a model driven approach to reconfigurations of satellite software

“…In the context of object-oriented languages, (Apiwattanapong et al 2007) try to highlight behavioral changes resulting from structural differences, e.g., due to subtyping and dynamic binding. (Phung-Khac et al 2008) propose to memorize design choices such that differences are emphasized by the design process.…”
