In this paper we consider skyline query evaluation and maintenance in wireless sensor networks. We devise an evaluation algorithm for finding skyline points progressively and a maintenance algorithm for skyline maintenance incrementally. We also conduct extensive experiments by simulations to evaluate the performance of the proposed algorithms on various datasets. The experimental results show that the proposed algorithms significantly outperform existing algorithms in terms of network lifetime prolongation.Keywords: Data sets; Evaluation algorithm; Maintenance algorithms; Network lifetime; Query optimization; Skyline point; Skyline query; Algorithms; Indexing (of information); Knowledge management; Maintenance; Sensor networks; Wireless telecommunication systems; Wir Query optimization; Skyline query; WSN200910.1145/1645953.16461412016-02-24
