| 摘 要： | 提出了基于属性簇的时空数据聚集查询算法.数据聚集以簇为WSNB-TREE存取目标,将无线传感器网络（WSN）所覆盖的区域划分为多个属性簇,同质传感器的数据便于实时统计处理和分时段查询;对于事先确定监测的区域,以区域划分数据聚集簇,将异质传感器的聚集数据进行汇集,从而快速过滤获取需查询的“事件”,进而实现对全网的时空数据聚集查询.

| Abstract: | In this paper,based-on attribute-cluster,a new spatio-temporal data aggregation query algorithm is proposed.Data aggregation uses clusters as WSNB-TREE's storage object.Areas which are covered by wireless sensor network are divided into attribute-clusters.The data of the homogeneity sensors are easy to do real-time statistics and segmental query.Areas which a confirmed in advance are divided into a few data aggregation clusters,then the data of the heterogeneity sensors are aggregated.Hence,less time is tak... |
