You need to be more precise. You mean, time between send() and receive 
()? Or do you mean time between the first bit being transmitted  
(after CSMA) and receive()? Or do you mean the time between the first  
bit being transmitted and the last bit being received (but not  
including the code time to signal receive())? Or do you mean the  
propagation time for an individual bit? These times all have  
different values. What, specifically, are you trying to measure?
