We apply multiple query optimization to batches of pull (on-demand) requests in a mobile database system. The resulting view can answer several queries at once, and it is broadcas...
Abstract. In this paper we consider databases representing information about moving objects (e.g. vehicles), particularly their location. We address the problems of updating and qu...

Query processing on mobile sensor networks requires efficient indexing and partitioning of the data space to support efficient routing as the network scales up. Building an index ...
The need of using spatial vector data for web-based and mobile applications has been increasing rapidly. Vector spatial data is difficult to generalise (that is, to derive a suita...
We present a database correlation method combined with Bayesian estimation for mobile location in GSM networks. The final location request can be estimated using different ways. T...
