Wireless sensor network data fusion in layer based on hierarchy
LI Tong-fen · Modern Electronics Technique · 2014
Data fusion of wireless sensor networks can effectively reduce the data traffic among sensing nodes and energy consumption of nodes,and prolong the life of networks. A node hierarchical algorithm is proposed in this paper. The specific data fusion algorithm is added into the sensing node inside layer. The Pauta criterion is utilized in the algorithm the to detect the abnormal data which are received by nodes. The principal components analysis(PCA)is adopted to fuse the remaining data.The simulations experiment indicates this algorithm has a high data fusion accuracy.
