Pervasive applications want to describe in simple ways which context information they need about users, and be notified when low level context matches specified constraints defined by semantic expressions. In this paper we report our experience while implementing our Context Query Language and using it in a real context framework to support mobile context-aware applications in two European-funded...
Empowered smart objects have become a part of people everyday activities due to the evolution of pervasive computing technologies. In such scenario context awareness plays a fundamental role in enabling adaptation and contextual services. Up to now a lot of efforts have been done in representing context information such as location, time and users identity. At the same time not much attention has...
Context-aware applications do not always adapt their behaviours in ways that users expect due to a variety of reasons. Applications that lack intelligibility are often incapable of offering explanations to users as to why they decided to adapt their behaviours in certain ways, and providing feedback mechanisms for users to take control of any unwanted adaptation. This can lead to loss of user trust,...
The following topics are dealt with: pervasive computing; communications workshops; information quality; quality of service; ubiquitous communications; ubiquitous services; pervasive communities; service clouds; sensor networks; middleware; system support; social networking; security; context modeling; context reasoning; mobile peer-to-peer computing; pervasive collaboration; pervasive learning; pervasive...
Unwanted and untimely interruptions have been a major cause in the loss of productivity in recent years as they are mostly detrimental to the immediate task at hand. Multiple approaches have been proposed to address the problem of interruption by calculating cost of interruption. The cost of interruption (COI) gives as a measure the probabilistic value of harmfulness of an inopportune interruption...
Conventional layered protocols are not capable to handle the vagaries of Wireless Mesh Networks (WMN) such as rapidly changing wireless channel quality, battery power and network topology. Most WMN cross-layer proposals to overcome these problems utilize only a limited set of parameters from the concerned layers rendering them incapable of network and system wide optimizations as they do not consider...
Pervasive computing refers to a seamless and invisible computing environment in which ubiquitous and connected computing devices gather information about the environment. Such computer-enabled artefacts represent a new category of smart products where objects are aware of their surroundings and cable of supporting users in various tasks. However, the complex and dynamic domain of smart products is...
This paper describes the SimCon (Simulated Context) Generator which combines data on the state of a Virtual Reality building with the SimCon Model to generate interactive location context for the rapid evaluation of Smart Building Applications. The paper evaluates the simulated context against physical readings. The SimCon Model does not set out to replace deterministic models, but rather allow for...
Context-aware applications are becoming commonplace in everyday life thanks to recent advances in mobile devices, sensor capabilities and wireless communication networks. However, making the manipulation of context information efficient is still an important issue. Taking into account the quality of context data becomes a corner stone of an efficient context management. In this paper, we argue for...
Smart objects are gradually integrating into people's everyday life. While many context-aware solutions for pervasive computing environments do not consider users social aspects, we believe smart objects should be social-aware. So Smart aims at filling the gap in social understanding of the user environment, presenting an ontology based context model to support social context representation and automated...
