Wavelet transform is a recent signal analysis tool that is
already been successfully used in image, video and
speech compression applications. This paper looks at the
Wavelet transform as a method of compressing computer
network measurements produced from high-speed
networks. Such networks produce a large amount of
information over a long period of time, requiring
compression for archiving. An important aspect of the
compression is to maintain the quality in important
features of signals. In this paper two known wavelet
coefficient threshold selection techniques are examined
and utilized separately along with an efficient method for
storing wavelet coefficients. Experimental results are
obtained to compare the behaviour of the two threshold
selection schemes on delay and data rate signals, by using
the mean square error (MSE) statistic, PSNR and the file
size of the compressed output.
