This research focuses on the issue of modeling continuously moving regions and a new approach called constraint rectangle is presented. According to the new approach, a continuously moving region is represented as a set of constraint rectangles and both x-dimension and y-dimension of each constraint rectangle are functions of time. We develop algorithms to represent a continuously moving region into constraint rectangles and prove the correctness of the algorithms. Furthermore, a prototype is implemented to demonstrate the rightness and effectiveness of the new approach. The experiment results show the constraint rectangle model is not only able to represent continuously moving regions effectively and practically, but also able to support historical and future queries on continuously moving regions. |
