Spectrum Density Analysis on Router-level Internet Macroscopic Topology
|
Abstract:
Analysis of spectrum density and SLS(signless Laplacian spectra) on router-level macroscopic toplogy was performed.Firstly,we found in experiments that five analysis results of spectrum density on five sampling topologies showed highly similarity proving that Internet is a system of self-similarity as well as the ability for sampling topology to resemble the whole Internet topology.Secondly,obvious difference between the spectrum density analysis results of sampling topology,ER graph and BA graph indicated ...
