Pervasive computing has created a need to profile users of these systems in a way never required in traditional computing. To pursue many of the commonly expected goals of pervasive advertising, we also need rich sources of profile information to build up a model of a user's identity and so target ads to them more effectively. We present an advertising(More)
Context-aware services are driven by sensed data from both real and virtual worlds. Building effective pervasive systems involves administration and fine tuning of sensors toward optimal operation. Difficulties arise because sensors are prone to inaccuracies through miscalibration, malfunction and component limitations. Any incorrect values of sensed data(More)
Information about community structure can be useful in a variety of mobile web applications. For instance, it has been shown that community-based methods can be more effective than alternatives for routing messages in delay-tolerant networks. In this paper we present initial research that shows that information on hierarchical structures in communities can(More)
—We propose a prototype for a real-world, human network proximity experiment with detailed recordings of the position of individuals. Our aim is to provide a comprehensive dataset to investigate the internal correlations between mobility and network properties, as well as to compare our results with different datasets, involving different social groups or(More)
New software for gathering and disseminating information makes it easier to develop services for sensor-rich environments. Pervasive computing provides a means of broadening and deepening the reach of information technology (IT) in society. It can be used to simplify interactions with Web sites, provide advanced location-specific services for people on the(More)
