Research on model of distributed data aggregation in WSN based on wavelet transform
Dang Xiao-cha · 2014
For the problems of hardware and energy of wireless sensor, the article puts forward a model of distributed data aggregation in WSN based on wavelet transform(DDA-WT). The model improves the original loop structure, adds the data detection procedure to reduce the amount of sensory data, which also exploits the lifting scheme to process the data matrix from nodes of ring topology in order to low the complexity of transport the fused data. The simulation results confirm the DDA-WT can low the energy consumption of nodes and prolong the lifetime of network.
