Current research in pervasive computing, as well as in the fields of mobile telecommunications and device manufacture are opening the way for convergence between mobile telecommunications and the traditional Internet towards the Future Internet. The ubiquitous computing paradigm integrates information processing into the objects that surround us in our(More)
Pervasive computing envisions a world where people are surrounded by numerous communication and computing interconnected devices that are invisible and assist users in their everyday tasks in a seamless unobtrusive manner. Most pervasive computing research initiatives aim towards the realization of smart spaces, i.e. fixed spaces that provide pervasive(More)
Context management systems are expected to administrate large volumes of spatial and non-spatial information in geographical disperse domains. In particular, when these systems cover wide areas such as cities, countries or even the entire planet, the design of scalable storage, retrieval and propagation mechanisms is paramount. This paper elaborates on(More)
Context awareness is an inherent feature of pervasive computing. It enhances the proactiveness of the system thus requiring less user attention and fewer human-machine interactions, it supports intelligent personalization features, and it can assist the system to address the user requirements considering the current conditions. Nevertheless, in such(More)
The emerging pervasive computing services will eventually lead to the establishment of a context marketplace, where context consumers will be able to obtain the information they require by a plethora of context providers. In this marketplace, several aspects need to be addressed, such as: support for flexible federation among context stakeholders enabling(More)
Context awareness is an essential cornerstone in future pervasive computing systems. It has the potential to greatly reduce the user attention and interaction bottlenecks, to give humans the impression that services fade into the background, and to support intelligent personalization features. Nevertheless, in order to create such an environment, a growing(More)
This work gives an overview over the challenges for context management systems in Ubiquitous Computing frameworks or Personal Smart Spaces. Focused on the integration of context inference in today's context management systems (CMSs) we address important design decisions for future frameworks. The inference system we have in mind is probabilistic and relies(More)
