LDCQ满足误差限制的偏差优化问题

Optimization of deviation limit under error limitation in LDCQ

提出了位置相关连续查询 (LDCQ)在满足误差限制的条件下进行偏差优化的问题 ,分别给出考虑了累积偏差和最大瞬时偏差时的信息费用的定义 .由于偏差优化的结果就是要使得信息费用的值为最小 ,再加上这些优化结果与移动对象的运动方式有关 ,这样就产生了不同的优化结果 .对累积偏差信息费用下的立即线性更新策略。

This paper proposed the deviation optimization under error limitations. Due to different considerations, information cost was defined differently. The definitions onThe Cumulative Deviation and the Maximal Instantaneous Deviation were given. This paper discussed some of the optimizations, the Linear Update Policy, the Delayed Linear Update Policy under the information cost definition of Cumulative Deviation, and random moving pattern under another definition of Maximal Instantaneous Deviation.
