As a famous member of R-tree family, R*-tree is widely used in multimedia databases and spatial databases, in which NN (Nearest Neighbor) search is very popular. Based on the observation that the objects are not well-clustered in R*-tree leaf nodes, this paper proposes an approach to improve NN search performance of R*-tree by introducing clustering technology to R*-tree. The experimental result indicates that our improved R*-tree has much better NN search performance than the original R*-tree.
