While the Kolmogorov-Smirnov test is good in theory, in practice,
you'll find that no distribution is exactly a power-law (of course),
unless you have really small networks. At least this is my experience.
Btw. there is also an R package called 'degreenet' which fits various
kinds of power-law distributions to discrete data.
Best,
Gabor
