Abstract
Continuously monitoring kNN queries in a highly dynamic environment has become a necessity to many recent location-based applications. In this paper, we study the problem of continuous kNN query on the dataset with an in-memory grid index. We first present a novel data access method – CircularTrip. Then, an efficient CircularTrip-based continuous kNN algorithm is developed. Compared with the existing algorithms, our algorithm is both space and time efficient.
