    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 environments, various types of context informati... View full abstract»

    In this paper we present an integrated view for modeling and reasoning for context applications using OWL DL. In our case study, we describe a task driven approach to model typical situations as context concepts in an OWL DL ontology. At run-time OWL individuals form situation descriptions and by use of realization we recognise a certain context. We demonstrate the feasibility of our approach by p... View full abstract»

  • An API for integrating spatial context models with spatial reasoning algorithms

    Publication Year: 2006, Page(s):6 pp. - 23

    The integration of context-aware applications with spatial context models is often done using a common query language. However, algorithms that estimate and reason about spatial context information can benefit from a tighter integration. An object-oriented API makes such integration possible and can help reduce the complexity of algorithms making them easier to maintain and develop. This paper pro... View full abstract»

    There are a number of possible sources for information about the environment when creating or updating a context model, including sensorial input, databases, and explicit modeling by the system designer. Another source is natural language, either in the form of electronic text (e.g., the World Wide Web) or speech. In this paper, we investigate the implications for context models when some of their...

    Once devices have been distributed around us, it is essential to model the context in which we interact on a daily basis in an appropriate way. In this sense, we should ensure that the devices chosen should be completely suited to needs. Our aim is to create applications to facilitate the user's daily activities, without any extra effort in terms of interaction, if possible. In this work we presen... View full abstract»

  • On representing situations for context-aware pervasive computing: six ways to tell if you are in a meeting

    Context-aware pervasive systems are emerging as an important class of applications. Such work attempts to recognize the situations of entities. This position paper notes three points when modelling situations: (1) there can be multiple ways to represent a situation; (2) a situation can be viewed as comprising relations between objects and so recognizing a situation boils down to determining if a p...

    Groupanizer is an extension of groupware and constitutes a development platform to integrate user-centric information for the benefit of groupware applications. User-centric context is used in a collaborative manner to positively link and reinforce group member idiosyncrasies. In order to do so, monitoring of the user's daily context is essential, and thus, one aspect we aim at integrating is user... View full abstract»

  • Deterministic and probabilistic implementation of context

    This paper addresses the problem of implementing an abstract context model. First, the abstract context model is represented by a network of situations. Two different implementations for the situation model are then proposed: a deterministic one based on Petri nets and a probabilistic one based on hidden Markov models. Both implementations are illustrated and applied to real-world problems View full abstract»

  • Balancing autonomy and user control in context-aware systems - a survey

    Application autonomy can reduce interactions with users, ease the use of the system, and decrease user distraction. On the other hand, users may feel loss of control over their applications. A further problem is that autonomous applications may not always behave in the way desired by the user. To mitigate these problems, autonomous context-aware systems must provide mechanisms to strike a suitable... View full abstract»

    With the increasing availability of mobile devices and their usage by many different kinds of users, the context used by an application on this kind of device, in no longer static. The changes in context can have different kinds of impact on the user interface. In this paper, we refine our earlier work on the specification of context information and its effects within the task model, a model that ... View full abstract»

  • Maximum weighted matching with interference constraints

    In this paper, we study the problem of utility maximization in multi-hop wireless systems. To study the effect of wireless interference constraints on the utility maximization problem, we introduce a new class of weighted matching problems, namely maximum weighted K-valid matching problems (MWKVMPs). For K = 1, MWKVMP corresponds to the well studied maximum weighted matching problem (MWMP) in the ... View full abstract»

    In this paper, we address the problem of gathering information in a central node of a radio network, where interference constraints are present. We take into account the fact that, when a node transmits, it produces interference in an area bigger than the area in which its message can actually be received. The network is modeled by a graph; a node is able to transmit one unit of information to the... View full abstract»

    Given a wireless network, we need to assign transmission power to each of the nodes, that will enable communication between any two nodes (via other nodes). Moreover, due to possible faults, we would like to have at least k vertex-disjoint paths from any node to any other node, where k is some fixed integer, depending on the reliability of the nodes. The goal is to achieve this directed k-connecti... View full abstract»
