I reinstalled ns-2.31 again, detailed steps:
1. tar -zxvf ns-allinone-2.31.tar.gz
2. cd ns-allinone-2.31
3. export CC=gcc-4.1 CXX=g++-4.1
4. ./install
then I follow your advice in the link:
http://www.linuxquestions.org/questi...rror-940388/#5
./ns test4maccon.tcl seems well, nam test.nam still appears "node i is not defined". However, when the topology script is changed into random.tcl, it nam well.

Solutions

Concerning the node not defined problem:
1st define your nodes positions (x,y,z) coordinates 2nd Define node size. By that you'll be able to view them in nam without errors

Concerning the add-channel problem generated from start simulation button in CRCN GIU:
Just create your traffic,topo and other parameters and after that use your terminal to compile by ./ns yourfile.tcl , however I prefer not using that GUI.

harshav you have to install java correctly and if you did otherwise you will get to CRCN problems, anyway I did not use the CRCN GUI try to write and run scripts of your calculation and drawings instead.

crcn throughput.awk

hi there,
is there any command to run throughput.awk that will relate to our throughput on my crcn?

as u mention before this:
echo | awk -f Throughput2007.awk

the results:
Average Throughput[kbps] = -0.00 StartTime=1000000.00 StopTime=0.00
Average Throughput[kbps] = -0.00 StartTime=1000000.00 StopTime=0.00

how can i fix this??
thank you in advance

"scenariowcett.tcl" : Unknown file.

You can attach scenariowcett.tcl to a new post, as scenariowcett.tcl.txt

Attachments : That's the paper clip tool in the 'Advanced Editor'.

thank you for your help knudfl..
thank god, the throughput.awk script that you gave me previously working perfectly..

i just want to know that the node below represent CR users or PR users?

for {set i 0} { $i < $val(ni)} {incr i} {
set chan_($i) [new $val(chan)]
}


#configure for interface and channel

$ns_ node-config -ifNum $val(ni) -channel $chan_(0)


for {set i 0} {$i < $val(ni) } {incr i} {
$ns_ add-channel $i $chan_($i)
}

for {set i 0} {$i < $val(nn) } {incr i} {
set node_($i) [$ns_ node]
$node_($i) set recordIfall 1
$node_($i) random-motion 0 ;# disable random motion
}


source $val(cp) ; #source topology and traffic file generated by others

# Tell nodes when the simulation ends
for {set i 0} {$i < $val(nn) } {incr i} {
$ns_ at $val(stop).0 "$node_($i) reset";
}
$ns_ at $val(stop).0002 "puts \"NS EXITING...\" ; $ns_ halt "
proc stop {} {
global ns_ tracefd
$ns_ flush-trace
close $tracefd
exec nam scenario2.nam &
exit 0
}
puts "Starting Simulation..."
$ns_ run


-->if it represent the CR user, what command should i put to add the node that represent primary users?

# 25 .

Repeat : Attach your files as ..
scenariowcett.tcl.txt, and scenario2random.tcl.txt,
by using the "paper clip tool" !


P.S. : If you show code in a post, code tags is a must.
* http://www.linuxquestions.org/questi....php?do=bbcode
* http://www.linuxquestions.org/questi...gs-4175464257/
I.e. type [/code] at code end, and [code] at code start.
*** Please edit post #25 to use code tags.

Which node ? What do you mean ? Please rephrase.
