Unanticipated Dynamic Adaptation of Context-aware Services
نویسندگان
چکیده
Usually, for building context-aware services, the developer must anticipate all the possible contexts elements and their states: user preferences, physical resources, location, etc. This anticipation is required in order to specify service and contextspecific adaptation rules, which are necessary for the adaptation management. Because of this, the adaptation rules are not reusable and the service cannot react to unanticipated context changes. In this paper, we propose a platform for dynamic and unanticipated adaptation of component-based services. Our solution is based on a knowledge representation describing the service and the context as a whole system. Based on this service-context representation, the adaptive platform is able to check the adequacy between the service and the context and to search for solutions if necessary. The difference between the classical approach and our approach is that we use only general rules. We have tested our architecture using a prototype that shows that a forum service may be adapted to the user language without using service and context-specific rules.

Chisel: A Policy-Driven, Context-Aware, Dynamic Adaptation Framework
We argue that the software user, the developer, the designer and indeed the application logic itself all possess invaluable intelligence to gear how software should adapt itself to changing requirements and changing context. We present Chisel, an open framework for dynamic adaptation of services using reflection in a policy-driven, context-aware manner. The system is based on decomposing the pa...

Context-aware services often need to adapt their behaviors according to physical situations and user preferences. However, most of the existing approaches to developing context-aware services can only do adaptation based on globally defined adaptation logic without considering the personalized context-aware adaptation needs of a specific user. In this paper, we propose a novel model-driven appr...

Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...

The modern human is getting more and more mobile having access to online services by using mobile cutting-edge computational devices. In the last decade, the field of context-aware services had led to emerge several works. However, most of the proposed approaches have not provided clear adaptation strategies in case of unforeseen contexts. Dealing with this last at runtime is also another cruci...
متن کاملDetecting Faults in Context-Aware Adaptation
Internetware applications are context-aware. They adapt their behavior based on environmental changes. However, faulty adaptation may arise when these applications face unanticipated situations. Such adaptation faults can be difficult to detect at design time. One promising approach is to statically analyze model-based context-aware applications exhaustively for all potential faults. However, i...
