摘要: This paper presents a research study on skyline path queries. Given source s and destination d road network multiple search criteria (e.g., short distance travel time), query returns set of non-dominated paths from to d. These are called paths. Efficient computation queries is very challenging due expensive traversals extensive comparisons in dominance tests. In this paper, we explore the characteristics paths, based which novel algorithm SkyPath proposed. To narrow down scope for result partial test full devised as two components SkyPath. Evaluation results show superiority over state-of-the-art approaches.
