“…Some general proposals about how to architect a self-adaptable software system have already appeared [6][7][8][9]. These proposals suggest architectural frameworks which can be used to support the implementation of suitable adaptation methodologies, possibly tailored to specific application domains.…”

Abstract. Increasingly complex information systems operating in dynamic environments ask for management policies able to deal intelligently and autonomously with problems and tasks. An attempt to deal with these aspects can be found in the Service-Oriented Architecture (SOA) paradigm that foresees the creation of business applications from independently developed services, where services and applications build up complex dependencies. Therefore the dependability of SOA systems strongly depends on their ability to self-manage and adapt themselves to cope with changes in the operating conditions and to meet the required dependability with a minimum of resources. In this paper we propose a model-based approach to the realization of self-adaptable SOA systems, aimed at the fulfillment of dependability requirements. Specifically, we provide a methodology driving the system adaptation and we discuss the architectural issues related to its implementation. To bring this approach to fruition, we developed a prototype tool and we show the results that can be achieved with a simple example.

“…The goals of [6] are not dissimilar from ours, as they try to capture the essence of self-adaptive systems, identifying it in computational reflection (one of the key features of self-adaptive systems according to [52] as well). The FORMS modeling primitives can be instantiated and composed in a variety of ways.…”

“…The literature includes valuable works aimed at capturing the essentials of adaptation both in the most general sense (see, e.g., [49]) and more specifically fields such as software systems (see, e.g., [68,13,52,5,65]) providing in some cases very rich surveys and taxonomies. A prominent and interesting example is the taxonomy of concepts related to self-adaptation presented in [68], whose authors remark the highly interdisciplinary nature of the studies of such systems.…”

Abstract. We present a white-box conceptual framework for adaptation developed in the context of the EU Project ASCENS coordinated by Martin Wirsing. We called it CoDa, for Control Data Adaptation, since it is based on the notion of control data. CoDa promotes a neat separation between application and adaptation logic through a clear identification of the set of data that is relevant for the latter. The framework provides an original perspective from which we survey a representative set of approaches to adaptation, ranging from programming languages and paradigms to computational models and architectural solutions.

“…These changes might include stopping and starting of applications and their components, configuring their connections and parameters, or changing device settings [14]. In the context of WSNs, reconfiguration become fully effective if the reconfiguration service retains fine-grained control over what is being reconfigured, by updating only some selected functionalities to minimize energy consumption.…”

Abstract. Wireless Sensor Networks (WSNs) are increasingly being deployed for applications with dynamic requirements. Moreover, these applications are likely to be run on nodes with different sensing parameters and capabilities. Addressing these issues in higher layers of WSNs architecture such as middleware and application, beside the consideration of lower layers, is of high importance. Reconfiguration of application software is an effective approach for addressing such issues. The special characteristics and limitations of WSNs make the requirements to the reconfiguration mechanism quite different from what has been previously proposed for other types of networks. In this paper, we propose a new software component model, namely ReWiSe, for achieving lightweight and fine-grained software reconfiguration in WSNs. In this model, a component can be reconfigured at the behavior-level instead of at the component-level. We discuss how the new component model can make the reconfiguration process lightweight in terms of component state preservation, component dependency checking, and new update unit granularity.
