[ns] packet in queue waiting time - wireless senario

[Andrew Tang <atang@cse.unsw.EDU.AU>]

Hi,

I am trying to analyse the time spent in a queue for a wireless node.

What I am hoping to do is to find the average "packet delay" to compare
several
Wireless MAC protocls, namely CDMA/CA, TDMA and several that I have have
modified. Is it safe to assume the time take for a packet from the agent
to reach the mac layer is the approximate time spent in the queue e.g

from a regular trace file

s 5.019047619 _1_ AGT  --- 33 cbr 1000 [0 0 0 0] 
s 5.202000000 _1_ MAC  --- 33 cbr 1072 [5 0 1 800]

or is there a more correct alternative, without needing to modify the
source. 

Thanks,
Andrew
