Hi.

Please edit section "$ns_ node-config", lines 155 .. 168.

A backslash means "this sentence will continue in the next line"

.... which will fail when the following line is empty.

(This error is well known. Happens e.g. when copying text from a HTML site / a file.html ).

Edited to ....

$ns_ node-config -adhocRouting $val(rtg) \
    -llType $val(ll) \
    -macType $val(mac) \
    -ifqType $val(ifq) \
    -ifqLen $val(ifqlen) \
    -antType $val(ant) \
    -propType $val(prop) \
    -phyType $val(netif) \

I didn't understand sir,

that section is correct as you have written it.

Would you please explain to me. 

thank you

these are the errors :

Lines 155 .. 168 :  No spacing between the lines is allowed. Your copy in the first posting has double "line feeds".

Correct is .....

Hello, ah okay understood,

Now the error shown :   

              node 0 is not defined...missing required flag -x in w -t 100

                    missing required flag -y in w -t 100  

                    parsing error in event

                    node 0 is not defined...

What should i do now sir ??

Hi.

May have something to do with with some missing arguments. There are theoretically seven :

[lindex $argv 0]  ....  ....  [lindex $argv 6]

.... see the first lines in your file.

Not unusual in an ns2 command. Can be like : $ ns file.tcl 1 2 2 4

... I did try out some various commands : $ ns usman.tcl 30 2 0 5 10 10 0.1    etc. etc. but they all failed.

[sadjida lebid]

hello sir, 

when i tried what you said, this is what happened :

Hi.

First :  Images with text are not at all appreciated

https://unix.meta.stackexchange.com/questions/4086/psa-please-dont-post-images-of-text

"You should avoid posting pictures of text. Pictures can be hard to read. Text is easier to read in different screen formats, can be copied and pasted, as well as is search engine addressable, making it easier for people to reach this post who may have a similar issue."
My comments : I guess you know how to copy-paste a text.

About "$ ns usman.tcl 30 2 0 5 10 10 0.1" : 

I didn't suggest this. I specifically mentioned that  none of the arguments I tried out were working.

[sadjida lebid]

Hello,

Sorry about that sir, I know it's not recommended but I have a problem when I copy paste from virtual machine/windows to windows/virtual machine (m using Fedora virtual machine with virtual box)it didn't work even the clipboard is bidirectional so that's why I posted an image.

I know it didn't work for you, I just wanted to show you what it showed me cuz I'm struggling with this code, I couldn't execute it, I'm stuck in this step.

Thank you.
