(English Abstract)
With the development of location aware techniques and mobile devices, the interests of location based services (LBS) have been highly increased. In this paper, we propose a spatial index structure that provides efficient query processing for the moving objects. The proposed index structure is based on a grid structure that provides direct accesses to data pages. It also uses the splitting policy of the kd-tree to make a leaf node. In addition, each leaf node maintains the links to neighbor leaf nodes like B -tree to avoid unnecessary parent node accesses to search a neighbor node. It is shown through performance evaluation that the proposed index structure outperforms the existing schemes.
