| 摘 要： | 针对以能量有效的方式收集传感器网络空间相关性数据的问题,本文提出了一种新的基于位置感知的无线传感器网络聚类算法.算法根据用户查询误差门限和基于位置信息的节点感知数据相异度矩阵,进行无监督数据挖掘,将监测区域划分成信息等价域.每个等价域选取域内当前剩余能量最大的节点作为簇头,网络通过移动代理收集簇头感知信息,从而减少了传输数据量,有效节省了网络能量.

| Abstract: | A novel clustering algorithm based on location aware in wireless sensor network is proposed in order to solve the problem of collecting spatial correlated data with energy validity.According to the user-provided error-tolerance threshold and sensing data similarity matrix based on location information,the algorithm performs unsupervised data mining task and then divides the monitoring range into several equivalent information ranges.Only one node per equivalent range is selected as the cluster-head by prese... |
