A new distributed algorithm of data compression of hierarchical cluster model in sensor network is proposed. The whole sensor network is mapped into a hierarchical cluster model, and different wavelet transform models are used to do data compression in inner and super clusters respectively, according to the relative regularity of sensor nodes deployed in the inner clusters, and the relative irregularity of sensor nodes deployed in super cluster. Theoretical analysis and simulation results show that, the new method has good performance of approximation, can compress data and reduce the amount o...
