摘要: 提出一种使用Broadcast Disks 算法来分布位图索引的空中索引方法,根据数据项访问概率,使用位图作为数据广播的索引,减少了移动终端等待数据时保持激活状态的时间,达到节能的目的。

关键词: Broadcast Disks;位图索引;数据广播;访问概率;节能

Abstract: Bitmap index distributed with broadcast disks technique is introduced in this paper. According to the access frequency, bitmap index is used to index broadcast data and the time of probing the arriving time of needed data items is reduced

Key words: Broadcast Disks; Bitmap index; Data broadcast; Access frequency; Energy conservation
