With the advent of ubiquitous computing environments it has become increasingly important for applications to take full advantage of Context aware computing to increase the satisfaction of the users in entertainment services. The contextual information, such as, environmental, social, task, Spatio-temporal and personal information has to be considered to offer greater services to the user without...
A key requirement for a distributed collaborative application is that all participants see the same copy of a shared window-object at different points in time (WYSIWIS). This is needed to maintain a cohesive view of the problem. We recognize that user actions are generated based on their understanding of the context of the problem, where context is defined in terms global view of the shared window...
Reliable recognition of activities from cluttered sensory data is challenging and important for a smart home to enable various activity-aware applications. In addition, understanding a user's preferences and then providing corresponding services is substantial in a smart home environment. Traditionally, activity recognition and preference learning were dealt with separately. In this work, we aim to...
Context-awareness is one of the key features of ubiquitous paradigm. To intelligently and sensitively deal with dynamic environment, a methodology specifying the relationships between the contexts and services needs to be developed. It is difficult to verify the correctness of the existing models on context with respect to timeliness. In this paper we propose an approach which includes timing constraint...
Context-awareness is a key issue in pervasive computing. Context-aware applications are prone to the context consistency problem, where applications are confronted with conflicting contexts and cannot decide how to adapt themselves. In pervasive computing environments, users are often willing to accept certain degree of context inconsistency, as long as it can reduce the consistency maintenance cost,...
With the growing advancement of ubiquitous computing (UbiComp), we are moving towards an era where access control and security policies will be based on context information. As context information represents real-world situations, it is associated with certain quality indicators that can directly influence the access control decisions. In this paper, we propose a quality-aware context-based access...
Handheld devices in a pervasive computing environment are prone to security as well as privacy violations, while discovering, sharing and accessing services and contents. Trust models are devised to fight against such violations and breaches. Although initial trust assignment is an important issue in evolving overall trust, a little amount of work has been done in this field so far. In pervasive smart...
The rapid adoption of model-driven design (MDD) methodology in SOA-based solution design requires an adaptive tooling environment that can systematically improve designers' productivity. Ideally, the environment should be flexible enough to both handle frequently changing requirements and support new features without intensive coding efforts. In this paper, we provide a coding-free enablement framework...
