[SOLVED] Meaning of Traffic and IT file generated after simulation in CRCN

jaibaba1 · 03-02-2011, 12:59 AM

How to analyse the IT and Traffic file generated in CRCN simulation? What they represent i.e what is the format?

Ns2 ? Which version of 'ns-allinone-2.xx' ? ?

CRCN : Is that a protocol you have added ?
Then please provide a download link for the protocol / patch.
And a link to the CRCN documentation, please.

Thank you for showing interest.
ns-allinone-2.31.
CRCN is a patch for cognitive radio network available at http://stuweb.ee.mtu.edu/~ljialian/

Yes, that's old news.
Please read http://linuxsilo.net/docs/smart-questions_en.html
And http://www.linuxquestions.org/linux/...Ask_a_Question
I.e. we are not meant to guess, what you are doing.
*** The idea is, that by every question : the OS used ( Fedora<version>),
the application (ns-2.31), and the used commands must all be specified / shown.

The download links mean these
crcn.zip > http://stuweb.ee.mtu.edu/~ljialian/crcn.zip
CRCN.jar >
http://stuweb.ee.mtu.edu/~ljialian/C...e%203/CRCN.jar

So please show the command(s) you are using ( "CRCN simulation" )
to generate the files in question. ( "IT" and "Traffic file" ).
./ns test4maccon.tcl ? ./ns MRMAC.tcl ( > Trafficfile ).

Generally about analyzing (tr) files, example

I am sorry and thank you for guiding me.

My os is Fedora11. I provided that information in my profile and thought it need not to be mentioned.
I am using NS2.31 allinone version. I have installed CRCN patch in it.

I simulated the file test4maccon.tcl using command
ns test4maccon.tcl.

then 4 files namely test.tr, test.nam, IT and Traffic files generated.

Now i have found the format of IT and Traffic files in their website.

According to them IT file format is
Timestamp node id interference channel id

But in my case five columns are there. I can't understand what last column represents?

I have attached the IT file herewith.

I will try not to repeat the above mistakes.

Sorry, I didn't see the 'Fedora11' text in your profile, my mistake.

I get a similar result : ./ns test4maccon.tcl → → ITfile, 363.3 kB.

Code:

0.010000 0 0.000000 0 0
0.010000 0 0.000000 1 0
0.010000 0 0.000000 2 0
0.010000 1 0.000000 0 0

Anyway thank you....
Please inform me if you find anything relevant..

knudfl,
I find it..last column represent "Channel with minimum Interference".

It is in file /home/bikram/Desktop/ns-allinone-2.31/ns-2.31/common/mobilenode.cc
in the function PacketPr::IT_Calculate()
