| 摘 要： | 把整个无线传感器网络组织成类似于R—tree结构，区域的历史感知数据存储在该区域的数据存储节点上，查询时只需要查询数据存储节．羔，节省了查询需要的能量，而对历史非常久远的数据先进行压缩处理，再发送给基站存储，可防止数据丢失．实验证明，应用R—Tree的方法无论在存储还是在查询上都比本地存储法和基站存储法具有优越性．

| Abstract: | This paper proposes a method which can be used in history data storage and query.Undoubted,research on history data storage and query is of huge value in practical application,which includes many fields.For example,during implementation of wireless sensor network in environmental monitoring,it is necessary to query the static temperature during a time in some place,the history data query is essential.Two basic methods are referred: local storage and base station storage.Local storage requires for huge energ... |
