NS2

binteasim · 02-08-2013, 02:25 AM

I've lately successfully patched LTE as far as I think but I've two basic problems,first is that the trace file of a program that I'm running is empty secondly I get the following error when I run the code:

Code:

Which instructions ?
I guess you mean ns-2.33/tcl/lib/ns-default.tcl ?

Warnings : Can be ignored.

Errors : Please comment out line 66 with a hash mark ( # ) :
# Session/RTP::debug_ set 1
.... then you may be able to fix any other errors.

The perfect working script for 'ns lte' is still "eyana.tcl", by @eyana

$ ns eyana.tcl : Nam opens OK.

Well, then better install 'nam'.

binteasim · 02-08-2013, 09:08 AM

I did sir that's why I don't understand why is it giving this error.I installed ns-allinone-2.33 which has nam 1.13,I don't remeber any error during installation of nam.Do you still advise to install nam 1.14?

knudfl · 02-08-2013, 09:32 AM

# 5.

A nam build will most often fail. And the failing build is ignored,
like the other applications not required for the 'ns' build.
You will only be stopped at "./install" when tcl tk otcl tclcl ns-2.* fails.

Nam is an "extra application". Actually any nam version can be used.

Nam version 1.13 and 1.14 are identical, so far concerns Linux.
( 1.14 has an edit for 'Sun OS'. Ref. the file nam-1.14/CHANGES.html )

binteasim · 02-08-2013, 10:23 AM

OK Sir I'll install nam again and see what happens,I have one more question from you, you once had written somewhere that if one has to install more than 1 versions of NS2 he should not add it to path.You told me the procedure for installing more than one versions of NS2 in post#4 in the following link:

http://www.linuxquestions.org/questi...s2-4175445269/

I did follow those instructions but due to certain errors I had to reinstall NS2.Currently I have an LTE patched ns-2.33 which is added to path, In case I have to install more versions do I have to delete all lines from the .bashrc file under the heading of PATH or LD_LIBRARY_PATH as well.My bashrc has the following code,just in case:

Code:

# LD_LIBRARY_PATH
OTCL_LIB=/home/dba/Desktop/ns-allinone-2.33/otcl-1.13
NS2_LIB=/home/dba/Desktop/ns-allinone-2.33/lib

USR_LOCAL_LIB=/usr/local/lib

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB:$TRGRAPH_LIB

No entries are required to .bashrc or .bash_profile. Never.
Also when you have one only ns-allinone-2.xx install.
So you can just delete the added lines.

The ns executable is hard coded to know the path for its libraries.
And the "ns-allinone-2.xx xgraph" never works.
( Get xgraph : sudo apt-get install xgraph ).

Executable 'ns's : Copy all 'ns' to a different name, 'ns-lte' etc.,
and then copy all the new renamed "ns-*" to /usr/local/bin/ .
All LTE examples work OK with $ ns-lte example.tcl .

There is also an LTE Ubuntu package, post # 10 here
http://www.linuxquestions.org/questi...4175435660/#10

P.S.: Where did you get the Tracegraph files ? :
http://www.linuxquestions.org/questi...ph-4175447000/
I found no links for Tracegraph or 'mglinstaller'.

binteasim · 02-08-2013, 12:42 PM

Sir I followed your instructions and eyana.tcl is working thankfully (although along with the warnings I told you about).The other two files I have are not working as yet but I'll see to them InshaAllah.
Following two links can be used for downloading tracegraph:

http://www.angelfire.com/al4/esorkor/
http://ns-2.blogspot.com/2008/10/tra...ator-ns-2.html

I got it from the first link I beleive and read the instructions from the second.There's a visual trace analyzer available for NS2 also, if tracegraph doesn't work fine I beleive I should move to that(provided it works).Visual trace analyzer can be downloaded from the following link:

http://nsvisualtraceanalyzer.wordpre...yzer-download/

binteasim · 02-09-2013, 11:58 AM

Sir as per post #13 in the following link the command that someone has used for patching eurane is

Code:

zcat ns-eurane-1.12diff.gz|patch -p1

, should I follow the same or should I go for

Code:

patch -p0 < ns-2.30_eurane-1.12.diff

http://www.linuxquestions.org/questi...ta-etc-869957/

knudfl · 02-09-2013, 12:29 PM

# 10

The patch for ns-2.30 is 'ns-2.30_eurane-1.12.diff(.gz)'
http://eurane.ti-wmc.nl/eurane/

So it's : $ patch -p1 < ns-2.30_eurane-1.12.diff
Or : $ zcat ns-2.30_eurane-1.12.diff | patch -p1

binteasim · 02-10-2013, 04:25 AM

Thankyou Sir, it's patched except I have one problem and that is in case I run certain examples one of which is http://eurane.ti-wmc.nl/eurane/test_tcp.tcl.txt it gives me an error : can't open file idealtrace. I did search for the solution and in the link http://lists.ti-wmc.nl/pipermail/ns-...er/000081.html it is mentioned that idealtrace should be the same directory as tcl, now does that mean I have to save idealtrace in tcl folder or I have to save it in the ns-allinone-2.30 folder where tcl8.4.13 is present.

knudfl · 02-10-2013, 05:03 AM

# 12

"the same directory as tcl" : Here it means the current directory.
I think all the "eurane examples" will do fine in any location.
( Like /home/dba/eurane-examples/ )

test_tcp.tcl.txt, line 109, 110, 111 :
$bs setErrorTrace 0 "idealtrace"
$bs setErrorTrace 1 "idealtrace"
$bs loadSnrBlerMatrix "SNRBLERMatrix"
→ → that's current directory for 'idealtrace' and 'SNRBLERMatrix'
( http://eurane.ti-wmc.nl/eurane/SNRBLERMatrix.gz )

If the file had said e.g.: $bs setErrorTrace 0 ../idealtrace
.. or : $bs setErrorTrace 0 umts/idealtrace
.. then a specific "test_tcp.tcl location" would have been required.
( But then again, lines 109-111 would have been easy to edit.)

-

binteasim · 02-10-2013, 07:33 AM

I put the whole path which went something like $bs setErrorTrace 0 "/home/dba/X/idealtrace" etc. and it worked.Thankyou Sir!
Do you know if nam simulates umts because if I add any of the lines such as "set nf [open out.nam w]" and in the finish proc "exec nam out.nam" it says

Code:

nam cannot recognize the trace file lo.nam
Please make sure that the file is not empty and it is a nam trace

knudfl · 02-10-2013, 11:04 AM

# 14

I found a eurane example hs-dsch.tcl that creates a "hs-dsch.nam" file, 10 kB.
https://github.com/metrue/ns2-umts
> https://github.com/metrue/ns2-umts/b...er/hs-dsch.tcl
( README : "This is an ns2 + eurane on umts simulation project".)

$ nam hs-dsch.nam : No activity.

But may be hs-dsch.tcl will show how to get a nam result in the other examples.

Other info : http://eurane.ti-wmc.nl/eurane/EURAN...ls_itpp.tar.gz
> EURANE_multi_cells_itpp/simulation_scripts/ReadmeFirst.txt
> EURANE_multi_cells_itpp/code/ ns-eurane-113-itpp.diff Readme.txt
I will report back, if any interesting simulations in 'eurane.multi.cells.itpp'.
