Yes and no - ns2 itself does not use threads. But the event-based processing 
model does not need threads to allow for concurrent threads of control. That 
means two station can perform actions at the same moment in time. The 
simulator will serialize them and compute them sequentially. An event-based 
simulation does not need to care about real-time (wall clock time), it has 
its own time base and so can compute as much events (happening) at the same 
time as you need. The simulation time will stand still during the processing 
of an event and will jump to the execution time of the next event that has to 
be processed. 

Hope this answers your question.

Daniel.
