I have downloaded a ns2.31_fhmip.patch and change the version and copy the file into ns2.35 folder. Then, using "$ patch p1 < ns2.35_fhmip.patch. but after that, there is nothing come out. can anyone help me.

Welcome to LQ.

The patch is a text file. Please read the "ns2.31_fhmip.patch" :
To know that it will add / modify files in ns-2.31/ only.
Works perfectly like this example :

$ cd ns-allinone-2.31/ns-2.31/ && patch -p1 < ns2.31_fhmip.patch
$ cd ../ && export CC=gcc34 CXX=g++34 && ./install
$ cd ns-2.31/tcl/ex/fhmip/ && ln -s ../../../ns
$ ./ns fhmip_simula.tcl : Files traffic.nam, traffic.tr are created.
$ nam traffic.nam : A nice simulation.

Note : You can have as many versions of ns-allinone as you want,
installed at the same time. But do not add any path text to .bashrc.

Hello,
After installing FMIPv6 on ns2.31 on ubuntu 13.1 32bits using the procedure described below.
I have nam1.15 installed in the place of nam1.13 associated with ns2.31.
I visualized the animation using nam and the nodes are layed out badly (one on top of the other).
How can i fix the problem or replace nam1.15 by nam1.13 ?

# 3 .

The most reliable version is nam-1.14 (Or the identical 1.13).

So please use this binary : nam-1.14.i586.tar.gz
https://docs.google.com/uc?id=0B7S25...=CLPiyxo&hl=en
$ cd nam-1.14.i586/ && sudo cp nam /usr/local/bin/

And remember to delete any 'nam' text in .bashrc , if the *PATH text is present.

Hello knudfl,
I applied your suggestion and verified that i am using nam.1.14 but the problem persists.
Can you tell me how to build nam1.13 because when building ns2.31 it doesn't create a nam executable in the bin folder or provide me nam1.13 executable.

# 5 .

There is no diffence from nam-1.13 to nam-1.14, so far concerns "32bits Linux".

How to build nam-1.13 (or 1.14) :
$ cd ns-allinone-2.33/tk8.4.18/
$ wget http://bugs.gentoo.org/attachment.cgi?id=161242
$ patch -p0 < tk-8.4-lastevent.patch

Do a $ make distclean
.. in tk8.4.18/unix/ , and nam-1.13/
And run your "export CC=... CXX=... && ./install" again in ns-allinone-2.33/ :
Only tk4.8.18 and nam-1.xx will change,
.. hopefully you will now get a 'nam' that works.

** But : I don't think nam is causing the "poor node layout".
? Have you tried maximizing the nam window ?

Yes i maximized the window many times and nothing changed.
Note that i am simulating the FHMipV6 script fhmip_simula.tcl as it is.
I have another question:after the patching of ns2.31 with ns2.31_fhmip.patch am i installing FMIPv6 or just fmipv4.
I want to install FMIPv6 on ns2 whatever version.What can i do ?

# 7 .

I tried editing (Y settings) etc. in fhmip_simula.tcl .
No change. Please see my 'nam Display', attached to post #6.
