[ns] Delay anomaly

[Tema Teresa Johnson]

Hello all,
       I was trying to find out the delay distribution (MAC layer).I am
doing the experiment for different data rates.The delay with
200kbps datarate is found to be more than that with 400kbps.ie.
When u repeat the same experiment,the delay is concentrated on a
higher value for 200kbps. What can be the problem? Is there any
explanation for that?
Thanks in advance.
Teena.
