We are doing wireless static (802.11) chain topology simulation, for
determining energy consumption per successful packet received.
Actually we face segmentation fault (core dumped) for more than 4 CBR
simultaneous active traffics. For 4 or less simultaneous flows it works
In above case, we started the CBR traffics at 10 seconds and stop at
120 seconds. When we changed it to 10 seconds to 25 seconds resp, the
(segmentation fault) problem started after 6 simultaneous traffics.
We don't understand exactly, what is the problem? Is it some limitation
of the ns?
We are using:
1> ns 2.30
2> Operating System:
Ubuntu 7.10, The output of "uname -a" is:
Linux wsl1 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux
3> The machine has Intel Core 2 (Duo) processor and 2GB RAM,
I've read the FAQ, ns-problems page, and manual and I couldn't find the answer there
