You've asked a tough question. Here's my sense of the current world:
* reviewers of papers generally don't trust any publicly available
simulator to give accurate predictions of wireless results, except
in very carefully crafted scenarios (and often not then -- I've
had papers rejected due to simulation concerns even when I could
show that the simulation issues had been addressed -- there's that
* there exist simulators that can be trusted -- they've been verified
to have results that match what is seen in the wild -- but they are
proprietary. The simulator I know of has two useful features: it
runs the same code in simulation as it does on the actual radios and
it emulates the wireless communications environment (e.g. signal
* if you want repeatable experiments that have some grounding in reality
you'd do best to use an environment like Emulab's 802.11 testbed.
Hope that's useful!
