Anas, the delay is not the MAC, it is the RTR to the MAC, which is the
IFQ. The only time I see these delays is with lots of nodes and lots of
queued packets, say 50 queued and each takes 3 seconds to win contention
= 150 seconds for the packet to get out.

Dear all,
I have encountered a large delay end to end delay
and when I checked the out put file I see some of the packets have a very
large delay at MAC layer as shown below:
f 202.663960039 _25_ RTR --- 585 cbr 576 [13a 2b 19 800] --- [9:1 10:1
25 30] [17] 7 2
s 358.840523771 _25_ MAC --- 585 cbr 634 [13a 1e 19 800] --- [9:1 10:1
25 30] [17] 7 2
as it appears there is about 150 second at MAC layer
what is the bug here
I used NS2.33 under both Linux and sygwin all of them have the same bug
please help me
best regards
Anas
