基于更新日志的移动对象索引方法
Moving Object Index Method Based on Update Log
摘要
Abstract
This paper realizes a ULTPR-tree for moving objects with frequent updates, which is based on TPR-tree by adding a memory-based Update Log(UL). It uses grouping method to delete the records of moving objects in bulk, which decreases the cost of deletion maintenance of ULTPR-tree. Theoretical analysis and experimental results show that the update performance of ULTPR-tree outperforms TPR-tree and HTPR-tree.关键词
