In this paper, we design and evaluate an energy efficient data retrieval architecture for continuous aggregate queries in wireless sensor networks. We show how the modification of...
This paper introduces an approach for adaptively brokering queries for exploiting streams produced and consumed by devices with limited computing and storage capacities. Such devi...
An important problem for many location-based applications is the continuous evaluation of proximity relations among moving objects. These relations express whether a given set of ...
—A challenging issue for HCI is the development of usable mobile interfaces for interactions with a complex pervasive environment. We consider a need for interfaces which automat...
Service adaptation is fundamental to context-aware service provisioning and to the realization of the Virtual Home Environment concept, which is now an integral part of the 3G serv...
