NS2

OK Sir.

Sir, while installing ns2.1b7a I countered the following error

Code:

/home/dba/ns-allinone-2.1b7a/lib/libtcl8.3.a(tclLoadDl.o): In function `TclpUnloadFile':
tclLoadDl.c:(.text+0x235): undefined reference to `dlclose'
collect2: ld returned 1 exit status
make: *** [otclsh] Error 1
otcl-1.0a6 make failed! Exiting ...

Do you know anything about it's solution?

Why ns-allinone-2.1b7a ?
( The most old patches for simulations have been ported to later ns2 versions.)

'ns-allinone-2.1b7a' is too old to be used on any Linux OS from this century.

Sir I had to patch GPRS and I could find it only for ns 2.1b7a.

knudfl · 02-23-2013, 02:49 AM

GPRS

How about the default mtp.tcl ? ns-2.3x/tcl/ex/wireless-scripts/mtp.tcl
.. Which is already dealing with gprs ..

Other example http://samtrac.informatik.hu-berlin....=author&desc=1
> ns-2.29-click/tcl/ex/wireless-scripts/runall-tr.cmd
( ns-2.34/tcl/ex/wireless-scripts/runall-tr.cmd ).

Sir I tried the example at http://samtrac.informatik.hu-berlin....=author&desc=1after entering line 25 I got the following error:

Code:

cell topology
ns: stop: couldn't execute "../../../bin/getrc": no such file or directory
    while executing
"exec $GETRC -s $sid -d $did -f 0 out.tr |  $RAW2XG -s 0.01  -m $wrap -r > plot.xgr"
    (procedure "stop" line 14)
    invoked from within
"stop"

do you know anything about it's solution?

# 21 .

The link http://samtrac.informatik.hu-berlin....=author&desc=1
.. is meant as a hint that you already have GPRS in any ns-2.xx .

Using "runall-tr.cmd" , example :

1) cd ns-2.34/tcl/ex/wireless-scripts/
2) ./runall-tr.cmd
.. Or 2a) bash runall-tr.cmd

OK Sir I'll try it.

binteasim · 03-20-2013, 09:05 AM

Sir do you know of any software that can calculate data from trace files for ns2 and works for ubuntu 12.04? I've tried alot of them but most of them are old or have no proper documentation.I have to calculate throughput,jitter and delay and probably other parameters too.The software I used for eyana.tcl gives me a constant delay as far as I can read it.

Suggest : Try out 'Traceanalyzer' :
".. throughput, end-to-end delay, packet loss and jitter."

Thankyou sir I got it installed alright but it did not show any results for my .tr file and the bigger problem is that my computer got hanged both the times I was using it.

# 26. I guess it was an "SQL only traceanalyser" linked in post #25 ?

I don't know sir but probably the default format accepts .trc files,the tracegraph in the link http://www.nsnam.com/2012/09/tracegr...e-to-plot.html, I have used it before and I had the same error as I had it then.After installation there is a usual error

Code:

./trgraph: error while loading shared libraries: libmwsgl.so: cannot open shared object file: No such file or directory

I did try to install libXp.so.6 but there are a number of dependencies that need to be installed and the link I have for installing these dependencies doesnot offer anything for ubuntu I believe.

I have used the software in the link http://nsvisualtraceanalyzer.wordpre...yzer-download/, and this was the one I was talking about which gave me a constant delay for eyana.tcl.I am attaching a screen shot of the delay plot if you could have a look and let me know if I'm missing any details.

# 28 : "tracegraph202linux" http://www.4shared.com/archive/z_iw9...2linuxtar.html

1) tar xvf tracegraph202linux.tar.gz
2) cp mglinstaller.gz tracegraph202/
https://dl.dropbox.com/u/24623828/mglinstaller.gz
3) cd tracegraph202/
4) gunzip mglinstaller.gz
5) ./mglinstaller

6) export LD_LIBRARY_PATH=./bin/glnx86 && ./trgraph
... and the tracegraph GUI will open.

NS2 Visual Trace Analyzer : I do not use Windows©, so it's a "don't know".

binteasim · 03-24-2013, 12:47 AM

Sir I followed all the steps again and the error's the same

Code:

./trgraph: error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory

Any suggestions?
