Re: [ns] Traffic generation in a proc
Hi Nabila,
looks like you only declared ns as a global variable inside your
procedure. Is this sufficient? I am not sure, but maybe reading up on
local variables and their scope in tcl is a starter...
Please add any insight you gained into the ns2 wiki
(http://nsnam.isi.edu/nsnam/index.php/Main_Page) so that others can
learn about and from your work.

Re: [ns] Traffic generation in a proc
Hi,
I am still wondering about the no generation of a trafic when it is done by a
procedure although the same code made outside works, but when I put it in a
procedure it does not!!! anyone has an idea

Hi ns user,
Try to wirte the cbr traffic without procedure to show it is correct or not.
Like
# Traffic Source 1: Mobile node1->node3, flowid=1set udp1 [new Agent/UDP]$ns_
attach-agent $node_(1) $udp1$udp1 set class_ 1$udp1 set fid_ 1set cbr1 [new
Application/Traffic/CBR]$cbr1 attach-agent $udp1$cbr1 set rate_ 20kb$cbr1 set
packetSize_ 512#$cbr1 set interval_ 0.2
# Set loss monitor (to count bytes) at node 3set null1 [new Agent/Null]$ns_
attach-agent $node_(8) $null1
# Connect the CBR generator to the loss monitor$ns_ connect $udp1 $null1

Re: [ns] Traffic generation in a proc
it works without procedure but as I want the code to be in a procedure in order
to call it several times so I don't have to repeat writing it in different
parts of the program
thanks for help

Subject: [ns] Traffic generation in a proc
Hi every one,
I wrote a tcl proc for the generation of a cbr trafic :
proc generate_cbr_traffic {agent_src size rate start_time end_time} {
global ns puts "In generate cbr: $agent_src $size $rate $start_time
$end_time" set cbr_ [new Application/Traffic/CBR] $cbr_ set type_ CBR $cbr_ set
packetsize_ $size $cbr_ set rate_ $rate $cbr_ attach-agent $agent_src $ns at
$start_time "$cbr_ start" $ns at $end_time "$cbr_ stop"}
I made the connection of the udp agents outside the procedure , when I call the
procedure, in the NAM environment no traffic was generated ,
Thanks for your help
