We consider the challenge of dynamically adapting services to context changes that occur in ubiquitous computing environments (e.g., changes in a user's activity) and propose ...

This paper introduces a new concept of information that can exist in a mobile environment with no fixed infrastructure and centralized servers, which we call the Hovering Informati...
Currently, most wireless sensor network applications assume the presence of single-channel Medium Access Control (MAC) protocols. When sensor nodes are densely deployed, single-cha...
Abstract. This paper presents a surveillance system for tracking multiple people through a wide area with sparsely distributed cameras. The computational core of the system is an a...

As we gain access to increasing volumes of context data, we face the problem of moving this information from the sensors that produce it to the applications that consume it. Our ap...

Context-aware service platforms need to establish and manage trust relationships for users to know if the user's privacy policies are being enforced and for service providers ...

Effective and efficient power management remains one of the most formidable obstacles that must be overcome before Wireless Sensor Networks can be deployed on a widespread basis. E...
Accurately determining the location of devices is a key challenge in contextual smart sensing. This poster describes how IEEE 802.15.4 radios can be used for accurate proximity sen...

The research in the field of service discovery in mobile ad-hoc networks is characterised by a lack of quantitative research. Many ideas have been put forward but few have been tes...
