Title: Query processing about near future positions of moving objects based on spatio-temporal index structure
Abstract: This paper focuses on the query problems of indexing structure for moving objects.First,an integrated tree structure PQR-tree is proposed for indexing the moving objects in constrained movement.Second,an exponential smoothing approach for predicting the result of queries that refer to the future is implemented.The experimental results show that the approach achieves a better performance for query evaluation than TPR-tree.
