Abstract
In order to adapt to resources-constrained Wireless Sensor Network(WSN), an improved Fusion Algorithm of Hierarchical Data in Cluster for WSN is proposed on the basis of the Principal Component Analysis(PCA). Self-learning weighted method estimates measured variance of every sensor. The linear unbiased minimum variance estimate method is adopted, which is able to reduce the errors of measured datum of the cluster sensor nodes. The formulas of comprehensive support degree of each sensor and data fusion are obtained according to the PCA method. The application example and simulation results prove that the method is effective and reliable.关键词
