摘要

Continuous K-Nearest Neighbor (CKNN) query is an important type of spatio-temporal queries. A CKNN query is to find among all moving objects the K-nearest neighbors (KNNs) of a moving query object at each timestamp. In this paper, we focus on processing such a CKNN query in road networks, where the criterion for determining the KNNs is the shortest network distance between objects. We first highlight the limitations of the existing approaches, and then propose a cost-effective algorithm, namely the Continuous KNN algorithm, to overcome these limitations. Comprehensive experiments are conducted to demonstrate the efficiency of the proposed approach.
