WSN Data Management Based on Non-Standard 2D Haar Wavelet Transform

The WSN management based on non-standard 2D Haar wavelet transform was designed to reduce the data transmission between nodes.Since the wavelet transform can be used to decompose the data into wavelet coefficients on different scales for transmission,the wavelet coefficients can be reconstructed to recover the original data.The algorithm of non-standard 2D Haar wavelet decomposition implements the aggregation of data,but the algorithm of non-standard 2D Haar wavelet inverse transform implements the reconstruction of date.The result of the MATLAB simulation showed that the wavelet transform data management structure can decrease greatly the load of data transmission with the features of those data kept up.
