[ns] Steady state throughput
Dear NS-users, I would like to evaluate the steady-state throughput of a network of few nodes with respect to the packet arrival rate (PAR). For each PAR, I extract from the trace file the corresponding Throughput by using the following formula Throughput = (total number of bits received) / (simulation duration). Let's mentioned that in the simulation duration, the transient period is not considered. My problem is that I don't know how to compute the steady-state throughput. Because the throughput I am computing varies with the simulation duration. I tried to simulate with very long simulation durations (4000...6000 seconds), but there are still significant changes in the throughput values and the simulation takes too long time. How could I simulate the steady-state throughput? Thank you very much in advance for your help.

[ns] howto modify SFQ maxqueue_ variable
Hi guys,
maybe somebody can help me out here.
I have a standard link
$ns duplex-link $n2 $n3 100Mb 0.01ms SFQ
and I would like to change the maxqueue_ variable of the SFQ algorithm.
from the manual follows that
$ns queue-limit $n2 $n3 100
should work, however it doesn't.
In the code of sfq.cc I found
int SFQ::command(int argc, const char*const* argv)
{
if (argc == 3) {
if (strcmp(argv[1], "limit") == 0) {
maxqueue_ = atoi(argv[2]);
fairshare = maxqueue_ / buckets_;
return (TCL_OK);
}
if (strcmp(argv[1], "buckets") == 0) {
clear();
buckets_ = atoi(argv[2]);
return (TCL_OK);
}
}
return (Queue::command(argc, argv));
}
however, I don't know how to get access to the link
I tried
set sfq [ $ns duplex-link $n2 $n3 100Mb 0.01ms SFQ ]
$sfq limit_ 100
but that also didn't help.
I'm clueless.
Any ideas?
With kind regards
Matthias
[ns] how to analyse the trace file to calculate throughput and delay??
Hi all I am trying to analyse the new trace file format to get the throughput and packet delay.I have seen the awk script posted for this purpose.I am totally unfamiliar with awk and am getting syntax errors once I try to compile it.Can you please help with the script if anyone of you already have one to analyse the network throughput and packet delay.My trace file format is as shown below:This is a part of my trace file.

[ns] how to measure the size of received packet
hi,
i want to add a code in ns2.33(mac802.11.cc) to measure the size of the
received packet . i mean i want to put the size of the received or
transmitted packet in a variable and compare it with other parameters such
as DIFS, CW_ ,... in mac802.11cc .(if size of packet>Function(CW_) {...})
thx in advance.
