Poisson Distribution patch for ns 2.35

[amith khandakar]

Dear All

Can anyone help me in providing me with patch that has the Poisson Traffic generator in it.

Will Really appreciate it.
Regards

[Andreas Andreou]

Did you ever find a patch for ns-2.35. There is one for 2.28 and 2.29

[knudfl]

@Andreas Andreou ,,, Hi.

The old patches for ns227, ns228, ns229 :  I can't find any valid links for the "packages".

( poisson-patch-ns-2.27.gz, ns-2.28-poisson.patch.tar.gz, etc.)
... If you have the patches, could you please attach those to a new post ?

But I found "poisson.cc", originally for ns-2.26 :
http://www.iis.sinica.edu.tw/~cclljj/misc/notes/poisson.cc.html
Please also read the advices for creating the simulation : In the file poisson.cc .

It appears that the file poisson.cc fits nicely with ns-2.35, no issues with the build. (g++-4.4).
No edits done. Except adding  <TAB>tools/poisson.o \  to the Makefile.in , line 337 .
( Must be the last line in section OBJ_CC ).
... So I have attached my "patch" ,  poisson-ns235-files.tar.gz , for you to try out.
( I don't know if any code should be added to tcl/lib/ns-default.tcl ,  etc. : 
Please check with the old patches.)

This what I did :
cd ns-allinone-2.35/ 
tar xvf  poisson-ns235-files.tar.gz  && export CC=gcc-4.4 CXX=g++-4.4  && ./install

Yes I have them. Basically what I did was open the patch file and read it manually and accordingly make the necessary changes written. In that sense they are the same. However I have attached them. In the 2.28 I also have two seperate files which are the corresponding poisson.cc from the patch you found (Ling-Jyh Chen) and from the other (Kostas Pentikousis).

They are pretty similar but they do have a major difference in the getting the next time. Do you know the why's of both approaches by any chance and can you talk about it here when you look at them. Other than that Ling uses the lambda while Kostas uses the interval (1/lambda). Both overload the init() with almost the same code but Ling also calculates the nextPkttime which seems redundant since start also does that. Kostas overloads the start() as well but keeps it the same except he deletes the line for the nextPkttime and uncomments timeout which is said to do if you want the generator to send immediately upon start and Ling overloads timeout() which he keeps almost the same but replaces send with agent_->sendmsg(nbytes) which is what the body of send is in the parent class application...

@knudfl,...Hi,

Can I use poisson-ns235-files.tar.gz in ns-2.33?? If yes then how?

Do I have to follow the same steps you already mentioned for the ns-2.35?

Thanks

Bilal

Thanks

[knudfl]

@Bilal Khan ,  Hi.

Please explain the reason for using ns-2.33 .

1) ? Is it becuase you want to use "poisson" together with another "extra added protocol" ?

2) You can have as many versions of ns-allinone-2.xx as you want, installed at the same time :
.... /usr/local/bin/{ ns226, ns229, ns233, ns234, ns235, ns235-poisson }.
I.e. copy ns to ns-name, and # cp ns-name /usr/local/bin/
 → → All examples.tcl can be run with 'ns<any-name> example.tcl'

Thanks for your prompt reply. 
I just installed poisson patch on ns-2.33.
The reason I'm using ns-2.33 is that it has IEEE 802.11 PCF (point coordination function) developed in it. 
So I wanted to use PCF along with poisson traffic.

@Bilal Khan.

A poisson patch or a "patch-package.tar.gz" will change or overwrite your files, and I don't think you want that.

"poisson-ns235-files.tar.gz" is the edited files for ns-2.35.
.... Which I made up from the original patch = ns-2.29-poisson.patch. (Attached.)
Please read the file to know the changes.
And unpack poisson-ns235-files.tar.gz in a new empty folder to see the changes for ns-2.35 .
Details : See the files.rej in  test-patch__poisson-ns229.tar → attached.
And : Please read my above post "4/3/14".

Note : I cannot make a new patch for ns-2.33 not knowing the 'IEEE 802.11PCF' changes

I tried the patch for ns2.35, it does not work, it gave me the following error:

invalid command name "Application/Traffic/Poisson"

any idea?

Mustafa

@Mustafa Altekreeti.

»» invalid command name "Application/Traffic/Poisson" «« :

You are using a wrong copy of the executable 'ns',  or you have a failed build.

HOWTO

tar xvf ns-allinone-2.35_gcc5.tar.gz

I am using ns2.35 so far and it is working fine for me,

I applied your patch for ns2.35 to be able to use Poisson traffic generator and it gave me the above error,

[Mustafa Altekreeti]

what is the purpose of last command?

ns235-poisson ns-poisson.tcl


is it just an example?


[knudfl]

@Mustafa Altekreeti

ns235-poisson ns-poisson.tcl  is my command for the default simulation example →

→ cd ns-2.35/tcl/poisson/ && ns235-poisson ns-poisson.tcl

I.e. ns235-poisson is a copy of the executable 'ns' patched with Poisson.

....  See my previous post.

Using "ns_new-name" is important when you have multiple ns2 installs.

See my example from one OS : usr.local.bin-05.18.txt

[knudfl]

@Mustafa Altekreeti.

Sorry,   "ns-poisson.tcl" is just a kind of Template.

Two Poisson examples are attached.
