Re: [ns] ns2 and netbeans or eclipse

[urashu06]

HI,
sometime back I have used eclipse to debug NS-2 but got so many errors and I
need to build a newer version of ns-2. It converts all the warning messages
in errors.

[ns] Support for Ethernet Switch module in Ns-2

[Mayank Sharma]

Hello,

My configuration is :

ns2 version : ns-2.33
Operating sys : Ubuntu 8.04 - The Hardy Heron

I have to simulate a LAN with Ethernet switches in a multi hop setup. I was
wondering if ns-2.33 release had the libraries and required support for
switches which do not use the CSMA/CD protocol which is implemented in the
legacy Ethernet.
I have come across this question a couple of times on ns user forums ( dated
2004, 2006 ) but were not answered.

It would be appreciated if you could help me out with this

Regards,

Mayank Sharma

[ns] asking about variable in RREP of AODV

[Irvan Supradana]

Hello all

Im irvan student from Indonesia. i want to make modification in aodv
especially in RREP process. I got a confused what is exactly mean of rp_src,
rp_dst. My first assumption rp_src is IP address of node which broadcast
RREQ and rp_dst is IP address of node replying RREP. But when i changed
 variable rt0 = rtable.rt_lookup(rp->rp_src); , i thought rp_src is IP
address of node replying RREP. any body can explain to me?especially
different between rt and rt0 (and their works).

Thank you so much

[ns] Adding static routes

[Alexandre Jaron]

Hello,

I built a wired topology in which I want to edit routing tables for a
certain number of nodes.
I want to tell a node, every packet coming from this node forward them to
that node. Just as simple as it is.

I found something on the Internet : [$node set ragent_] addstaticroute
   
But 'ragent' is unknown, and I don't know how to write down the arguments,
what is the interface arg? next hop, is it an address, a node ?

Looking forward to your answer,
Kind regards,

Alexandre Jaron.

[ns] Fwd: Routing issues

[Alexandre Jaron]

Hello,

I am an MSc student at the King's College and I am currently encountering
problems editing routing tables in NS2. Basically, I use a mesh topology,
and I want to add or create a basic routing table for a certain number of
nodes.
I want to tell a node: every packet coming from this node, forward them to
that node. How could I do that? If yes, can I make it in tcl script?

I am looking forward to your answer,

Kind regards,
Alexandre Jaron.

Re: [ns] Changing the sources file

[Mubashir Rehmani]

Hi Faraz,

You need to recompile ns2, so that the changes taken into effect by using

make clean
make
sudo make install

Moreover, it may happen that the printf that you inserted may not be
encountered by the program pointer. I mean, you need to put prinft in the
appropriate position of the mac protocol (cf. the pdf below for mac).

http://www.cs.binghamton.edu/~kliu/research/ns2code/note.pdf

Hope it helps

[ns] Changing the sources file

[Syed Faraz Hasan]

Hi NS2 Users,

I am trying to make some changes in the NS2 source files, attempting to modify 
the scan procedure in the 802.11 network simulations. I added an extra "printf" 
command in the mac/mac-802_11.cc and saved the changes. When I am running the 
tcl code for 802.11 infrastructure networks, it is not printing the extra 
message. This was just a simple check to see if the changes are working but it 
failed.
Can anyone tell me how a source file is changed in NS2?

Thanks,
Faraz

[ns] Calculate Call Setup Delay on SIP signalling

Dear All,
I'm doing project on SIP over DCCP using ns2 2.34, and in Mr. Masataka 
Ohta (Kanagawa University Japan) paper:  "Performance Comparisons of 
Transport Protocols for Session Initiation Protocol Signaling" there is a 
formula to calculate 
call setup delay, and I want to know how to do it in ns2 or awk or maybe in 
perl? Is there anyone can help me?
