it's a very minor point and of minority interest, but it seems, after years of simulating ambitious satellite constellation designs that don't get constructed or launched, that ns-2 simulations of satellite constellation networks do, in fact, match reality. This would be a lot harder to do with ns-3, which lacks ns-2's orbit simulator. Lloyd Wood http://about.me/lloydwood
