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 th is paper, based-on attr ibute- cluster, a new spatio- tem po ra l data aggregation query algor ithm is proposed. Da ta agg regation uses c luste rs asW SNB-TREE’s storage object. Areas wh ich are covered by w ire less sensor network are d iv ided into attr ibute- clusters. The data of the homogene ity sensors are easy to do rea-l time statistics and segm enta l query. Areas wh ich a con firm ed in advance are div ided into a few data aggreg ation c lusters, then the da ta o f the he terogene-i ty sensors a re aggreg ated. H ence, less tim e is taken to filter out the even ts wh ich a re needed to be quer ied, and then spa tio-tempora l data aggrega tion que ries are conducted in the who le netwo rk.
