| 摘 要： | 提出在位置相关连续查询(LDOQ)中保证满足误差限制的选择区域更新策略。通过给予不同区域内固定大小的偏差限来减少移动对象的更新次数和对计算容量的占用；同时通过延迟广播来减少广播信息数量。从而进一步优化了系统结构，减轻了系统负荷。

| Abstract: | This paper presented a strategy,Selected Area Update strategy for LDCQ to guarantee error limitation. By setting fixed deviation limits in different areas,it reduced the update number of moving objects and the occupancy of computation capacity. The broadcast messages by delaying broadcast locations of query boundaries were reduced. It optimized the system structure and the payload of the system. |
