[Battlemesh] ns-3 - Network Simulator

I think this is the basic difference between a network emulator and a 
network simulator, right?

The emulator runs real code in a virtual environment. The simulator runs 
code that simulates the behavior of the real code in relation to it's 

What I like about the simulation is that it technically can also 
simulate mutual interference in mesh networks. Not sure if and how this 
could be done with emulators. They might only have more like static 
settings for latency, jitter, packet loss with a predefined variance.

Maybe somebody can confirm or correct.
