The spatiotemporal database concerns about the time-varying spatial attributes. One of the important research areas is related to the support of various location-based services in mobile communication environments. It is known that database systems may be difficult to manage the accurate geometric locations of moving objects due to their continual changes of locations. However, this requirement is necessary in various spatiotemporal applications including mobile communications, traffic control and military command and control (C2) systems.
In this paper we propose the Bst-tree that utilizes the concept of multi-version B-trees. It provides an indexing method for the historical and future range query processing on moving object's trajectories. Also we present a dynamic version management algorithm that determines the appropriate version evolution induced by the mobility patterns to keep the query performance. With experiments we show that our indexing approach is a viable alternative in this area. |
