How to change traffic from cbr to Pareto/exponential in ns2.35(ubuntu 12.04)

Nindu · 10-16-2014, 02:46 PM

Hello everyone
i want to change traffic from cbr to pareto/ exponential
i have used the following code in my tcl file but no trace file is generated for this & the ouput is fatal error

Code:

                set p [new Application/Traffic/Pareto]
                $p set burst_time_ 500ms
                $p set idle_time_ 500ms
                $p set rate_ 200k
                $p set packetSize_ 512
                $p set shape_ 1.5
                
                #set e [new Application/Traffic/Exponential]
                #$e set packetSize_ 210
                #$e set burst_time_ 500ms
                #$e set idle_time_ 500ms
                #$e set rate_ 100k

i hv enable the pareto traffic & disable the cbr & exponential traffic
is this a right way to change traffic ???

thanx in advance

thanx sir for ur reply

but i already read about pareto/exponential traffic generation on google but don't understand where m going wrong

Code:

if {$val(traffic) == "Node-UDP"} {
	for {set i 0} {$i < $val(nodes)} {incr i} {
		set udp($i) [new Agent/UDP]
		$ns attach-agent $node($i) $udp($i)
		set dest [expr round([$randomNode value])]
		while {$dest == $i} {
			set dest [expr round([$randomNode value])]
		}
		set monitor($dest) [new Agent/LossMonitor]
		$ns attach-agent $node($dest) $monitor($dest)
		$ns connect $udp($i) $monitor($dest)
		set p [new Application/Traffic/Pareto]
                $p set burst_time_ 500ms
                $p set idle_time_ 500ms
                $p set rate_ 200k
                $p set packetSize_ 512
                $p set shape_ 1.5

for this simulation is done for 20 nodes but trace file is not generated
plz help

← #6 .

May be attach your complete file.tcl ?

Must be named <file>.tcl.txt ,
i.e. suffix .txt is a must for "text files".

Nindu · 10-19-2014, 12:39 PM

attached aomdv.tcl file

knudfl · 10-19-2014, 03:24 PM

← #8 .

* Forgot to tell you that your (edited) file.tcl
cannot have the same name as an already existing file.
The file in post #8 is not "aomdv.tcl". See ``1aomdv.diff´´.
And furthermore, the file has DOS (Windows©) characters,
not usable as is in a Unix/Linux environment.
( Easily fixed with $ dos2unix

)

When edited, no issues : $ ns aomdv-Nindu.tcl
.. The files ns.trc 213 MB, scenario.trc 1.5 kB are created.

Edited to include {Exponential and Pareto} :
$ ns aomdv-Pareto.tcl
OK, ns-P.trc 213 MB, scenario-P.trc 1.5 kB

thanx sir for ur reply

in file ns aomdv-Pareto.tcl all traffics(cbr/pareto/exponential) are enabled & it gives the output for cbr traffic but i want to find output (using different parameters like pdf.awk, genthroghput.awk etc) for pareto traffic .
like i said in post no 1 .

plz help......
