Location-dependent Skyline Query Processing in Mobile Databases

摘要：

Skyline query processing has received considerable attention from database and information retrieval research communities. However, the existing work on skyline queries mainly assumes data objects contain only non-spatial attributes. In this paper, we address the problem of answering locationdependent skyline queries efficiently over data objects with both spatial locations and non-spatial attributes in mobile databases. We show how to efficiently perform location-dependent skyline queries in a distributed mobile environment and propose a location-dependent skyline processing approach. We conduct extensive experiments in a simulated mobile database system, and the experimental results demonstrate the superiority of the proposed approach.
