802.11e in ns2.35

[rhean]

 I am currently installing the 802.11e for ns2.35. the instructions I am following if from this site: http://www.tkn.tu-berlin.de/fileadmin/fg112/Hard_Software_Components/Software/Simulation%20Models/readme_EDCA.txt . The instructions are said to be for ns2.28.

Still, I tried following the instructions and run the script file multi-udpflow.tcl. I got the following error:

invalid command name "Mac/802_11e"

    while executing

"Mac/802_11e create _o54 "

}

@Deepti Singhal ,  Hi .

Available patches / "patch packages" :  EDCA_ns-2_28-v1-0-2.tgz ,
edca-ns233.patch , 802.11e-DCA-ns235_091814.patch .
( The last two are attached.)

The files "mac/802.11e/" are the original old files :  g++ version 4.1.2 will work.

Ns-2.35, using, Ubuntu example :  $ cd ns-allinone-2.35/
$ patch -p0 < 802.11e-DCA-ns235_091814.patch
$ export CC=gcc-4.4 CXX=g++41
... and the executable "ns -802.11e" is created.
$ cp ns ns235-EDCA
$ sudo cp ns235-EDCA  /usr/local/bin/
$ ns235-EDCA multi_udpflows.tcl : Works OK, the file `out.tr´ ~800 MB is created.

Please specify your OS : a) The output from the command $ uname -m
b) OS  name and version ,,, then I can tell you which g++ 41 to use.
( Packages.deb  are available for all versions of e.g.  Ubuntu.)

invalid command name "Mac/802_11new"

    while executing

"Mac/802_11new create _o48 "

Other details asked by you are : 

a) Output of uname command is : i686
b) OS  name and version : Ubuntu 12.04 LTC

c) NS version: NS2.34

Please help me.

@Deepti Singhal ,  Hi .

There are no traces of anybody that ever tried to use the "mac2.pdf" files,
.. please see https://www.google.com/webhp?hl=all&gws_rd=ssl#hl=all&q=invalid+command+name+%22Mac%2F802_11new%22
.. and https://www.google.com/webhp?hl=all&gws_rd=ssl#hl=all&q=%22Mac%2F802_11new%22

So why not use the tested solution = "802.11e-DCA-ns235_091814.patch" ?

Hi,
I am new to ns2.
I am trying to apply the EDCA patch using the steps you provided. I am using ns 2.35 in fedora 20.
i have successfully completed till $ export CC=gcc-4.4 CXX=g++41.
But when i run $ cp ns ns235-EDCA, I get the following error.

cp: cannot stat ‘ns’: No such file or directory

What am I doing wrong?

@Tom Kurian ,   Hi.

»» I have successfully completed till $ export CC=gcc-4.4 CXX=g++41 «« :
There is no  "gcc-4.4"  or "g++41" in Fedora (20).   
So your ns2 build would fail  →  no 'ns'  →  no 'ns' to copy.

You can do :  Edit one file to use g++-4.4.x ..... gcc-4.9.x :
Line 41 in  ns-2.35/mac/802_11e/mac-timers_802_11e.cc
Edit from :  #include <iostream.h>
To :              #include <iostream>

Then you can run plain ./install  ( No 'export  <CC= >  <CXX= > )
.... with the updated  ns-allinone-2.35 :  ns-allinone-2.35_gcc482.tar.gz
https://drive.google.com/file/d/0B7S255p3kFXNSGJCZ2YzUGJDVk0/view?usp=sharing
.... ( The old 2011 version , ns-allinone-2.35.tar.gz may work too, that I haven't tested.)

@Tom Kurian ,   Hi again.

EDIT :   " Edit one file to use g++-4.4.x ..... gcc-4.9.x : "
Should be :                              g++-4.x.x ..... g++-4.9.x :


-

[knudfl]

...  And then we have a new EDCA patch ,  for all gcc4.x,  till 4.9.x :
(  mac-timers_802_11e.cc is now with :  #include <iostream> )
→ → `802.11e-EDCA_ns235_2015-gcc49.patch´
