Re: [ns] MANNASIM SENSORS EXTENSION
Hi, Did you try the Mannasim Examples available in the download section? http://www.mannasim.dcc.ufmg.br/download/mannasim-rede-plana.tcl http://www.mannasim.dcc.ufmg.br/download/mannasim-rede-hierarquica.tcl What errors do you get (if you don't write that, it's hard to help)? There also is a mailinglist specific to Mannasim, which would be the more suitable place to ask about it, since it is not part of standard ns2. https://listas.dcc.ufmg.br/mailman/listinfo/mannasim Best, -Matt Am Freitag, 17.

[ns] Floating exception
Hi all, I have a tcl script that works for one tcp protocol and now added some lines for other tcp protocol. Script is working for first tcp protocol and when start simulation for new one I have simulation start and after some time (after few minutes) I have Floating exception with no other output or details about error. At this moment the simulation stops, and enter another simulation (since I have many tests (simulations) started with one tcl script). Another simulation goes fine end and goes to third Anybody can tell me how to trace where is this errorwhat files to look, how to log changes and how to find that part of code . I have read something where it is sead that this happens when I devide with zero (), or when I have variable defined as integer, and my script gives it a floating value or something like that. But here, I don't know where to look , I have only this tiny output Floating exception I am using ns2 ver.2.29. Thank you.
Re: [ns] Installing ns-2.26 in FC5!
hi, Diana Asnani wanted us to know: Hi folks, Has anyone successfully installed ns-2.26 in FC5? It says tcl8.3.2configuration failed! Is there a way to fix the tcl? Please let me know.Thanks. If you can do without FC5 then have a try with mandriva LE2005 (limited edition 2005). It comes with gcc-3.4.3 and installation of ns2.28 and ns2.30 worked fine on it. Cheers, -- Luqman
[ns] Simulate sctp multi-homing over wired-cum-wireless network
Hi
I tried to simulate sctp multi-homing over wired-cum-wireless
network on ns-2.30
I have read the paper on
http://www.lib.ncsu.edu/theses/available/etd-05162005-094333/.
http://www.lib.ncsu.edu/theses/available/etd-05162005-094333/
According to The FAQS of the paper , I modified two parts.
1.$ns_ node-config -wiredRouting OFF
2.commented out the line
//Tcl::instance().evalf(\%s no-slot \%ld, name(), cl)
in classifier.cc
I created multihoming nodes(mobile node) in WLAN .
while i execute ... it shows the following error message which is
the same as the paper mentioned.
num_nodes is set 4
