This isn't a simple question to answer.
All simulators abstract some parts of what's going on and
simulator other parts with more detail.

Some of us (John Heidemann, Nirupama Bulusu, Jeremy Elson, Chalermek
Intanagonwiwat, Kun-chan Lan, Ya Xu, Wei Ye, Deborah Estrin, and
Ramesh Govindan) put together the paper "Effects of Detail in Wireless
Network Simulation" that discusses this question in more detail.  See
