Pervasive information systems give an overview of what digital environments should look like in the future. From a data-centric point of view, traditional databases have to be used...
Location-based services have attracted the attention of important research in the field of mobile computing. Specifically, different mechanisms have been proposed to process loc...
Sources of data uncertainty and imprecision are numerous. A way to handle this uncertainty is to associate probabilistic annotations to data. Many such probabilistic database mode...
In a data stream management system, a continuous query is processed by an execution plan consisting of multiple operators connected via the "consumer-producer" relationsh...
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...
