Data Compression Algorithm Based on Hierarchical Cluster Model for Sensor Networks
Tongsen Wang, Lei Wang, Zhijun Xie, Ronghua Yang · 2008
A new distributed algorithm of data compression based on hierarchical cluster model for sensor networks is proposed, in which, the whole sensor network is mapped into a kind of hierarchical clusters model firstly, and then different wavelet transform models are used to commit data compression in inner and super clusters respectively. Theoretical analyses and simulation results show that, the above new methods have good performance of approximation, and can compress data and reduce the amount of data efficiently.
