“…The second ones focus on formal aspects of context-aware application composition, in particular, on context modeling, specification of context-aware resources and context processing algorithms. Example solutions with advanced context-aware support are presented in [7,24,55,73]. Bottaro et al [7] developed a system for autonomous policy-based application composition and adaptation which targets late-binding and user mobility issues.…”

Ubiquitous computing environments advocate creating applications by plugging together various resources (mobile devices, displays, augmented everyday objects, and so on) and Web Services to support the user's everyday activities and needs. This approach is referred to as application composition, and such applications are called composite. Due to the dynamic nature of ubiquitous environments, application composition has to be supported at runtime, so that the applications are able to adapt to the situation within the environment and other contexts. Application composition is usually performed by autonomous context-aware mechanisms that provide limited or no control for users. Still, users need to be aware of their environments and be able to control and configure applications when they are composed and executed. Towards this goal we present in this article a context-aware application composition system based on the iCompose interface for composing and controlling applications at runtime. Users compose applications by simply touching the resources in the environment with their mobile devices, while the iCompose interface provides feedback and assists users by suggesting them possible further actions. The interface relies on a rule-based reasoner and utilizes various context sources to support users dynamically, according to the situation in which they compose applications. We present a complete implementation of the system and report the results of a user evaluation study conducted with 21 participants. This study assesses the issues of control, usability, feasibility and user acceptance of the iCompose interface for context-aware application composition and the prototype as a whole.Keywords: ubiquitous computing • interaction design • physical user interface design • application composition © Versita Sp. z o.o.

“…Indeed, as shown in SAFRAN [8], application's behavior adaption is also a crosscutting concern and a part of context-awareness mechanism [3]. Hence, as a result of contextual information collection, data will be used during a decision stage, also called situation identification stage.…”

Many adaptative context-aware middleware exist and most of them rely on so-called vertical architectures that offer a functional decomposition for contextawareness. This architecture has a weak point: it does not allow the system handling both dynamics of the changing environment and applications. To avoid this, we propose an approach for context-awareness based on a behavioral decomposition, and because each behavior must complete all functionalities necessary for contextawareness, we introduce an hybrid decomposition. It consists in a functional decomposition into a behavioral decomposition. This approach derives benefits from both decomposition, first allowing to handle environment and application's dynamics, second introducing reusability and modularity into behaviors.

Middleware for ubiquitous computing are having a mediator role in ubiquitous systems. They have to be able to handle both dynamics: the dynamic of the environment and of the application. But, at least, they must consider the dynamic of the underlying software infrastructure. To handle such a dynamic, we present in this paper a mechanism for adaptation called cascaded aspects of assembly (AA). The functional decomposition proposed by cascaded AAs allows to dynamically compose adaptations to manage the dynamic variability of the application and of its infrastructure. Because cascaded AA can be selected/unselected or edited at runtime, some others processes can manage them in various autonomous and decentralized processes to handle the other dynamics.
