Diffusion Wavelets-Based Analysis on Traffic Matrices

Traffic matrix describes the traffic volumes traversing the network from the input nodes to the exit nodes over a measured period. Such a matrix is very hard, if not intractable, to be obtained for a large network. We apply a new technique to analyze the traffic matrix by use of diffusion wavelet in this paper. It is shown that diffusion wavelet can do an efficient multi-resolution analysis on TM. The original TM can be reconstructed by choosing the diffused traffic in a particular level. This paper also shows there are a lot of potential applications by use of diffusion wavelet-based analysis on traffic matrix.
