Hi guys
I need help in ns2 programming as i am new to it.
The problem is: Imagine there are 3 nodes..A,B and C. Node A wants to send information to Node B but it does so by sending it to Node C first which then sends to B. And similarly Node B sends to A. In this simultaneously C doesnt send to both A and B.

This is the in built algorithm..but i want to change it to:
A and B send their packets to C and C sends both these packets to A and B..by ORing... In the receiver side...node A can receive the wanted packet and also B.
Where do i change the algorithm?? and wat all steps do i need to take to change this?
Please help me..

hi Swathinag, did u completed the problem you mention? i face the same problem as well, anybody can help, i am new in ns2 too ^^

hmm....i dint exactly solve it.. but i got more information on it.... it is Network Coding.. and i got some codes for Network Coding in ns2.. now i'll have to make changes in that.. Wat exactly are you doing in ns2?

hi Swathinag, sorry for late reply. i am doing network coding as well,but i will doing it on wireless network. can you share or teach me how to do that? i need a network coding node so that i can make change the routing protocol of the wireless network.

Hi Swathinag,

what patch are you using to implement network coding in ns2?
were you able to install it and compile succesfully?

hmm...i got an already made Network Coding in ns2.27 from the internet and i compiled it in mine. It had implemented Network Coding Routing protocol. It seems to be working fine...But i need to make more changs in that.

thx, i guess it's the same that I found on internet.
I'm running Ubuntu 8.04 and I had to tweak the installation of ns2.27 following these instructions (see knudfl's post):
https://www.linuxquestions.org/quest...9-10-a-782356/
but when I apply the NC and "make" i get compilation errors on the C++ syntax, so I guess it's a compiler's version issue (in this case its' gcc-3.3)
what compiler and linux distro are you using?

any hint from somebody else?

thanks in advance

Can you please provide me with the source code you found about network coding?
I need something to get familiar with network coding.

Thank you in advance

Best regards

Post #9, @electronnne : Welcome to LQ.

This thing `network coding' : Has it got another name ?
Very few usable results with Google .. ns2 Network Coding Routing protocol ..
https://www.google.com/webhp?hl=all#...uting+protocol
*** And : ns2 is all about network **

Example ?

Dear knudfl,

Thank you for your answer. I have already found these links but did not find exactly what i wanted (there is no combination of packets).
To be clear, I am totally a NEWBIE in ns2 and i have a basic level of c++

This new paradigm called network coding is simply XORing (combining) data (packets) by intermediate nodes (in a network of course) before transmitting them.


Maybe you could guide on how to do it please i am completely lost

Thank you

I am trying to change few lines in cmu-trace.cc. After compiling using the MAKE command, I am not able to see the changes in the trace file. Trying to change the lines in sprintf. Can anyone help me in this regard?
