 This page seems to suggest to turn off SSP by changing the default

 Let me know if that works.

Hi!
I tried that but still the same error. This are the flags passed to g++

g++ -c -O3 -march=pentium3 -pipe -fomit-frame-pointer -funroll-loops
-fexpensive-optimizations -fno-stack-protector -Wall

and the error while linking is still the same...
Thanks anyway!

[ns] How to implement a new Protocol in NS2?

2006-10-12 Thread Christian Kellner

Hello,

I'm a beginner in NS2 and have tested to implement a new example Protocol in 
NS2, using the Tutorial:

Implementing a New Manet Unicast Routing Protocol in NS2

masimum.dif.um.es/nsrt-howto/pdf/nsrt-howto.pdf

I did all changes who are necessary but I can't use this new Agent in a simple 
Tcl Script in the way like this, because I get the error message invalid 
command name:

.
.
.
set p1 [new Agent/TestProt]
$ns attach-agent $n2 $p1
.
.
.

Who can help me?

Re: [ns] how can we echange variable between layer???

2006-10-12 Thread Pedro Vale Estrela

If you pass these between c++ modules by calling TCL procedures, this is
very easy (but slow)

Start by checking this page

[ns] BIC TCP / CUBIC TCP under ns-2.29

2006-10-12 Thread Aleksandar Smolovic

Hi all,

Anyone have installed BIC TCP and CUBIC TCP under ns-2.29 ?

I have downloaded files (tcp.cc and tcp.h) from their site but they are for 
ns-2.26. Now, I need to make changes to my files in ns-29, since I cannot JUST 
use ns-2.26 files. I have downloaded ns-2.26 from NS2 site, find tcp.cc and 
tcp.h files and compare them with those downloaded from CUBIC site by using

#diff tcp_226-nomoduls.cc tcp_cubic_226.cc  diff_cc_files.txt
#diff tcp_226-nomoduls.cc tcp_cubic_226.cc  diff_cc_files.txt


Result is to many changes to be made. Now, I don't know what to do.

Am I missing something here ? It should be simple to install a modul.

[ns] How to implement aggregation?

2006-10-12 Thread g_fnoor

  Hi Everybody!
   I have to build a hierarchical network and then apply aggregation to
it, i already have the tcl scripts for the building the network, what i
need to know is, which C++ files do i need to change to implement the
aggregation? i mean how does one know what files to change in the ns
modules to add your own functionality.
   My project is to make a hierarchical network,not just one but its like
a 1:1 dual, 1+1 dual, 1:2 dual and 1:4 dual networks, i already have
the necessary files to build these networks, the next step is to
implement aggregation over these networks, and i do not know where to
start from?
Please help any guiding step would be really helpful. thanks a lot in
advance.

Thanking you

Regards,
Fatema.

[ns] NS2 + UCBT

2006-10-12 Thread Loreno Oliveira

Hi list,

sorry for this message. I know this is not the apropriate list for
discussing external NS modules, but the UCBT list seems to be no more
active, and I hope there are people here with some experience with UCBT.

Well, I have reproduced, using NS2 + UCBT, a scenario whose I have performed
some tests using real bluetooth devices. The problem is that the behavior
presented by UCBT is rather different from the behavior verified
empirically. Does anybody can help me with some hint of where, and how,
should I modify UCBT for modeling the bluetooth features I need to deal
with??

Thanks in advance!

Loreno


[ns] generic VBR Traffic - bit rate higher than the maximum rate set

2006-10-12 Thread ben

Hi,

Has anyone try using the generic VBR application made
by Håkan Byström? The source can be found here
http://mailman.isi.edu/pipermail/ns-users/2001-October/018453.html

I understand this code will vary the time interval
which packets are sent as well as the packet size. 

Application/Traffic/VBR set rate_ 16Kb
.
.
.
Application/Traffic/VBR set maxrate_ 32Kb;

The highest data rate for my simulation run is higher
than the maxrate parameter. Is this normal? I think
maximum rate should be below than the max rate. If it
is not normal then there is a flaw in my translated
code.Btw,I'm using a Java based network simulator.
Comments are appreciated.

Thank you very much.

Ben
