    摘要: In the wireless communication environments, k nearest neighbor (kNN) queries issued in the mobile device can find k spatial objects that are the nearest neighbors according to its current location. In this paper, we propose a neighbor link-based spatial index for processing k nearest neighbor queries in the wireless broadcast systems. Since the answered objects may be neighbors of each other, we add neighbor information to the index structure, which are interleaved with spatial objects, to speed up the query processing. From comparison, we have shown that our proposed index method performs better than the existing method.
