Re: [ns] Help me
: Hello any one! Can any one provide me TCL script to run DSR and AODV routing protocls. Our students are studying Adhoc wireless Networks as part of their curriculum I would like to provide them i.e my fellow college the TCL script of these two protocols , so that they can have practical ( simulation) idea of these two protocols and also brief note on how to analyse the trace files from these two protocols . *Also from where can i get TCL script for location aided routing protocol to implement in NS2* Eagerly waiting for the reply -- **R.Manjula Sr.Lecturer, Dept of ECE BITM, Bellary Karnataka. * -- **R.Manjula Sr.Lecturer, Dept of ECE BITM, Bellary Karnataka.

Hi, Thank you Sir, In my project, i am Using Hello Packets for neighbor discovery. But i don know how to create Hello Packets for neighbor discovery. If you have any idea, please share with me. It will usefull to me.

Re: [ns] help me regarding the make file plzzzzzz
Hello Tamer, I think there are two ns-2 groups, the releases earlier thank 2.30 and later thank and including 2.30. The first group requires older c++ compiler and you should only install them in a linux fedora version earlier than core 5. This applies to your 2.29, which should be installed either in core 4 or earlier. The latter should be installed int a core 5 or later release of Fedora. Hope this helps, Kamil https://crg.ee.uct.ac.za/~kamil On Sun, 2007-12-02 at 20:33 -0500, Tamer Ahmed wrote: Dea NS-Users, I have installed the ns-2.29 on machine under Linux Fedora and tried also with the ns-2.31.

Make a script like this one below and place it in you ns-allinone-2.30
directory.
When you need to run your NS simulations go to that directory and
source the script.
