Location-Dependent Skyline Query
April 27-April 30
ISBN: 978-0-7695-3154-0
Given a set of data points with both spatial coordinates andnon-spatial attributes, point a location-dependently dominates point b with respect to a query point q if a is??closer to q than b and meanwhile a dominates b. A location-dependent skyline query (LDSQ) issued at point q is to retrieve all the points that are not location-dependently dominated by other points with regard to q. In this paper, we focus on the query processing and result validation of LDSQ overstatic objects. Two algorithms, namely brute-forth and δ-scanning, are proposed. The former serves as the baseline algorithm while the latter significantly improves the performance via space pruning. We further conduct a comprehensive simulation to demonstrate the performance of proposed algorithms.
