Towards Increasingly Update Efficient Moving-Object Indexing

Current moving-object indexing concentrates on point-objects capable of continuous movement in one-, two-, and three-dimensional Euclidean spaces, and most approaches are based on well-known, conventional spatial indices. Approaches that aim at indexing the current and anticipated future positions of moving objects generally must contend with very large update loads because of the agility of the objects indexed. At the same time, conventional spatial indices were often originally proposed in settings characterized by few updates and focus on query performance. In this paper, we characterize the challenge of moving-object indexing and discuss a range of techniques, the use of which may lead to better update performance.
