  2. Hey Manoj, I see that you are working with CRCN simulator. I have jus started with it. Do you have any example scripts to run for it for the single radio multiple channel configuration. If you find some, pls let me know too

  3. Hi Serene!
    Visit CRCN official site.
    Download the CRCN gui jar file they provide.
    I guess there are some sample scripts bundled into it!

  4. Hello Manoj,

    I did check with the scripts there. I basically want to work with a single radio multi-channel environment but the channelindex_ variable that given in the packet header is not taking any values or the lower layer as they say should support this decision is probably not supporting the decision. Can you help?

    Thanks a lot!

  5. Hi Serene!
    I am sorry to say that apart from installing CRCN, I got no knowledge about it. I learnt the installation part to help out my colleagues who have just started into CRCN.

  6. Oh Thats so good to hear 🙂
    Instead of a thanks you can contribute your findings to the world.
    A small step can make a big change.

  7. LOKESH,
    I have the same problem at step 8, “make depend” error, have you solved it yet? I installed ns2 2.31.

    undefined reference to `hdr_wcett::offset_’
    collect2: ld returned 1 exit status
    make: *** [ns] Error 1

  8. for “make: *** [depend] Error 2″ in ubuntu do the following.

    sudo rm /bin/sh
    sudo ln -s /bin/bash /bin/sh
