How to patch GPSR to NS-2.34, which has OLSR already patched to it ?

Hello,

I have seen other threads where this topic is discussed.
I dont know how to refer to that thread here, I'm just giving the url of that page, http://www.linuxquestions.org/questi...-a-4175448663/

As answered by "knudfl" in that thread,

Anyway, it has been done before: gpsr-KeLiu-patched-ns234.tar.gz (14.4 MB)
Download link https://docs.google.com/file/d/0B7S2...it?usp=sharing
.. The patch origins from a huge "gpsr-KeLiu-ns234.tar.gz", 51.6 MB
by @ VanetG, post # 80 here ..
http://www.linuxquestions.org/questi...526/page6.html

Install :
1) cd ns-allinone-2.34/ && tar xvf gpsr-KeLiu-patched-ns234.tar.gz
2) export CC=gcc41 CXX=g++41 && ./install

I have NS-2.34 already installed with olsr patched to it. If I follow above method and perform ./install I will lose olsr.

So how to use this "gpsr-KeLiu-patched-ns234.tar.gz" in my running NS-2.34 ?

Looking forward for any suggestions..
Thanks.

Which olsr patch ? ? um-olsr-1.0.tar.gz ?
http://sourceforge.net/projects/um-olsr/

Please explain why you want to use your current ns-2.34 for GPSR-KeLiu.
( Many of the complex patches will make conflicting changes to the files.)

And : You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time. But do not add any path text to .bashrc.

Also : No problem having lots of different executable 'ns' :
Just rename all 'ns' to different names, like ns-umolsr, ns-gpsr-ke.
Example command : $ ns-umolsr olsr_example.tcl .

Ok..

If I simulate AODV/OLSR/GPSR in two different versions of NS2, would I get the same result?
If yes then my problem is solved, I will try to simulate GPSR on NS-2.33, as we get a proper patch file for it.

I'm under the impression that different versions of NS2 may give different results for same protocol(Ex: AODV).

Please clarify this..

Please tell which olsr patch you are using.

Sorry, forgot to mention about it.

I'm running NS-2.34 (no other NS2 versions) and I have patched OLSR with "um-olsr_ns-2.34_v1.0.patch" in NS-2.34.

# 5 . OK that's http://sourceforge.net/projects/um-olsr/, I guess.

The 'um-olsr_ns-2.34_v1.0.patch' will change these files :
** common/packet.h
** queue/priqueue.cc
tcl/lib/ns-agent.tcl
tcl/lib/ns-default.tcl
tcl/lib/ns-lib.tcl
tcl/lib/ns-packet.tcl
** trace/cmu-trace.cc
trace/cmu-trace.h

The ** marked files are also changed with gpsr-KeLiu-ns234.tar.gz.
So you will have to create new files {packet.h priqueue.cc cmu-trace.cc}
with both changes. And create a Makefile.in with all {olsr, gpsr} objects.

Yes I have used the same patch file which you mentioned.

Thanks for this information.

I will try to do that ..
