Context-aware computing is a recent approach to tailoring technology to the user’s context. As part of the vision for ubiquitous computing, it describes computing applications that change or adapt according to environmental characteristics. Research within the field have mainly focused on technical possibilities for representing a context in the use situation, however, not many context-aware ap...

Context awareness enables smart service discovery and adaptation for mobile and wireless hosts. The contextual data is acquired from sensors present in the smart space, which may be absent. The inherent noisy nature of wireless environments does not guarantee the gathering of correct data. A history module is thus required in conjunction with existing context-aware systems that overcomes these ...

In this paper we present conclusions, drawn from our research on context-aware systems. Based on reviewing the literature, from which we collected definitions of context and context awareness. We provide the basis for a taxonomy of context-aware systems grouped in eight categories. They include technical aspects of these systems as well as some views of privacy and security. Usefulness of taxon...

Growing number and complexity of context-aware systems requires a modeling framework suited for comparison of approaches. As a step towards modeling context-aware systems, we describe basic elements of such a framework. We introduce internal and external context information and define context models. We describe two conceptual architectures for context-aware systems and present their implicatio...

Context-aware recommender systems (RSs) have been mostly evaluated offline, and very few studies have tried to assess their benefit from the user perspective. Moreover, little research was previously dedicated to integrate the weather context into RSs that could benefit from that information, such as tourism applications. This paper presents a novel context-aware mobile recommender system, name...

We present the design and implementation of a working prototype system that enables self-configuration in mobile ad hoc networks (MANETs) by exploiting context awareness and cross-layer design principles. The driving force behind the proposed system is to allow for selfconfiguration of MANETs by enabling them to be adaptive to varying conditions. Emphasis is placed on describing the requirement...

Aspects based on join points that occurred in the execution history of a program provide a powerful way to make applications aware of their context. We present HALO, a logic metaprogramming approach based on temporal logic, that is designed with context-awareness in mind. A number of illustrative examples demonstrate HALO’s expressivity, including expressions about past events which contain var...

In this paper, we propose a health and environment monitoring service for solitary seniors using semantic web technologies (ontology modeling, semantic annotation, and ontology-based context awareness). This service defines and logically deducts the environmental conditions which threaten the health of the solitary seniors. This service includes solitary senior, guardian, social workers, health...

Ambient Intelligence (AmI) is a new research field aiming at building digital environments that are aware of the humans presence, their behaviors and needs. Among the key features, context-awareness plays the most important role in any ambient intelligence system. In this paper, we provide an overview of the notion AmI with its key technology features, typical contextaware frameworks and existi...

Self-regulated students are able to create and maximize opportunities they have for studying or learning. We combine this learning approach with our Mobile Context-aware and Adaptive Learning Schedule (mCALS) tool which will create and enhance opportunities for students to study or learn in different locations. The learning schedule is used for two purposes, a) to help students organize their w...
