Re: [ns] throughput calculation>>>>>>>>>>>>>>>>>
Hi, There are several ways to compute throughput. If you use TCP, the simplest way is to measure the sequence number and divide it by simulation time. You add the following into your simulation script ... $ns at 10.0 "$ftp stop" $ns at 10.1 "puts "puts \"The final TCP sequence number is [$tcp set $t_seqno_]\"" $ns at 10.2 "$ns halt" Then, you can compute the number of transmitted packets in 10.0 second simulation time.

Re: [ns] warning:no class variable Trafficfile::debug_
Hi, I think your problem may be caused by 1. You did not bind variable debug_ to the OTcl domain. Go to the Class TrafficFile and see whether the variable debug_ is bound properly. 2. Class TrafficFile does not have the variable debug_ at all. In this case, you have to declare it in Class TrafficFile.

Re: [ns] how can I turn off the energy trace?
I konw how to turn it off now.
In file MobileNode.cc, there is a function named MobileNode::log_energy()
which will be called by class WirelessPhy everytime, we only need to delete
several lines in function log_energy().
void
MobileNode::log_energy(int flag)
{
if (!log_target_)
return;
Scheduler &s = Scheduler::instance();
/*if (flag) {
sprintf(log_target_->pt_->buffer(),"N -t %f -n %d -e %f", s.clock(),
address_, energy_model_->energy());
} else {
sprintf(log_target_->pt_->buffer(),"N -t %f -n %d -e 0 ", s.clock(),
address_);
}*/
log_target_->pt_->dump();
}

[ns] Generating background web traffic
Hi, I'm trying to recreate the experiments from this paper http://www.hamilton.ie/net/pfldnet2007_cubic_final.pdf in ns. Some experiments study the impact of web traffic on the CUBIC. What would be the best/simplest way to simulate web traffic in ns? Should I use a Pareto traffic sources with an UDP agent? The paper mentions mean time between requests and mean connection size in packets. What would be reasonable values to assign to the rate_ and shape_ parameters? -- Jasin
Re: [ns] warning:no class variable Trafficfile::debug_
Hello, > warning:no class variable Trafficfile::debug_ > see tcl-object.tcl in tclcl for info about this warning I was having a similar problem, and I found the solution here, as I posted a few days ago to this list: http://nile.wpi.edu/NS/ Click on Otcl linkage, and search for 'warning' on the page and read about that. Basically, you need to set this variable (debug_) in ns-default.tcl (located here in my case: cphelps/ns-allinone-2.31/ns-2.31/tcl/lib/ns-default.tcl). The format of how to set the variable is as shown in the file: SuperClass/Class set _variable_name_ # eg Trafficfile set debug_ 1.0 Hope that helps. 8-) > I tried adding "Trafficfile set debug_ false" in > ./tcl/lib/ns-default.tcl as mentioned in very old posts but > unfortunetly it doesnt work in my case.

Hi there, is there any universal way to calculate packets throughput and delay with or without use of certain scripts, i've tried a couple of scripts for this purpose but they don't seem to work!!

[ns] wireless.tcl vs wireless-test.tcl
What is the different between example ~/tcl/ex/wireless.tcl and ~/tcl/ex/wireless-test.tcl ? I found that the different is not just the number of nodes (50->3), sim time, movement file and traffic generator. some of the proc (proc create-god and proc cmu-trace ) are not used in wireless.tcl. some of the external file (source ../lib/ns-mobilenode.tcl, source ../mobility/$opt(rp).tcl, source ../lib/ns-bsnode.tcl, source ../mobility/com.tcl). Does anybody can explain why this different must be made rather than just change the number of nodes, sim time, movement file and traffic generator only? many thanks..

[ns] warning:no class variable Trafficfile::debug_
Hi, I am trying to use some trace files to generate traffic but When I run the simulation I get the warning message: warning:no class variable Trafficfile::debug_ see tcl-object.tcl in tclcl for info about this warning I tried adding "Trafficfile set debug_ false" in ./tcl/lib/ns-default.tcl as mentioned in very old posts but unfortunetly it doesnt work in my case. Does anyone has any ideas to solve this problem? Thanks, I appreciate. Francesco
