Re: [ns] simulation time in ns-2

[Arun_Sathanur]

Happened with my simulations too. I ran the simulations for 100 seconds.
I left out the 5 seconds at both ends of the simulation and results are
consistent.

Arun

If you like to know the values in a steady state you sould run the
simulation 
for at least several minutes. Especially in the first few seconds you
can 
experience several strange effects. Something I often see is a storm of
ARP 
packets at the beginning of a simulation because all stations start to 
communicate at about the same time. So, it is sometimes better to
discard the 
results from the first seconds.

[ns] wrong node routing agent... problem continues

[Cenker Demir]

Hello All,

Related to my question about creating a clone routing
protocol, and 
according to Mr.Estrella's suggestion I included the
ns-lib.tcl to the 
beginning of my simulation script as below. I got the
errors that I 
attached.

I also run ns in tcl/lib, and wrote "source
ns-lib.tcl" and I got 

can't set "defaultRNG": invalid command name "abort"

error line. I have no clue what is wrong... Any
suggestions?

Best regards
Cenker

Re: [ns] Help: address of an agent's associated node

[Pedro Vale Estrela]

At the time of creation, add to it an instance variable called mynode, eg

$tap set mynode [$node id]

then, at run time just check the variable:

otcl: $tap set mynode 
C++  tcl.evaluate("%s set mynode", name());

Look into "tcl/lib/ns-node.tcl : instproc attach ..." how an agent is attached 
to a node. I didn't tried but you should get the Node reference from the 
node_ field in the agent.

[ns] please help me to simulate attacks on the Ad-hoc networks

[Ashutosh Srivastava]

   Dear all ,  
 For a project I  need immediate help . 
Actually I have to simulate some attacks(on ns-2
)possible in the Ad-hoc networks:  
1) sink-hole 
2) worm-hole 
3) Sybil attack 
4) Rushing attack 
5) Denial-of-Service and Flooding 
6) Black Hole
  What these terms mean , for this purpose
I am attaching a document containing basic  terms and 
definitions .Please , it would be very kind of you if
you can send me the simulation scripts for any of
these (on ns-2) and also the method to run them .Also
, let me know if there is any software to run ns-2 on
Windows XP
   I am unable to simulate these attacks
because I don't know how to use ns-2(rightnow I am
running out of time).
 I shall be very obliged if you will help me out
.Also , I am attaching a document
regarding the way I want the output statistics , this
paper contains information about the Denial of Service
attacks but nowhere the scripts have been provided for
simulation.
Desperately awaiting your kind
reply.
 With best
regards.

If you have some actual applications that create the traffic you should go for 
network emulation. 

Otherwise you need a simulation model of the applications inside ns-2. There 
is already one for HTTP traffic. For EMail traffic I cannot tell you. For 
VoIP traffic generation you should search the mailing list as this was an 
often ask question in the last year. 

The IPv6 stack could be a major problem if you rely on specific features. 
Maybe the Network Simulation Cradle project can help you with this ->

[ns] get mobile node by address

[christoph schroth]

Hi all,

I have a question to you all, which is related to my previously posted one:

How can I access a mobile node (and its data) out of its queue, its agent
etc.?

Can I access it similar to the way a "normal" node can be accessed?

(e.g., with the help of the function "get_node_by_address")?


Thank you so much,

[ns] NS for performance evaluation

[lekkie omotayo]

 Hi guys,
I need to use ns2 to evaluate the performance of web, email, and VoIP
traffics over IPv6 in a wireless network.
I am a newbie 2 d  tool. I just need pointers and steps to what to evaluate
(e.g bandwidth, latency, QoS). Also, I will appreciate if any one can give
me a head start into doing this. I really don't now  what part of ns2 to
extend or manipulate though av seen some tutorials but they r just for
simulation and monitoring packets. I need to implement ns2 for the said
projects. Any help will be appreciated.

If you like to know the values in a steady state you sould run the simulation 
for at least several minutes. Especially in the first few seconds you can 
experience several strange effects. Something I often see is a storm of ARP 
packets at the beginning of a simulation because all stations start to 
communicate at about the same time. So, it is sometimes better to discard the 
results from the first seconds.

Re: [ns] "wrong node routing agent" error... I couldn't findanything helpful in the archive...

[Pedro Vale Estrela]

For otcl changes to the default library, also check if calling "source
ns-lib.tcl" at the beginning of the simulation solves your problem.

Also check the example I give in

Yes, that's exactly these staps that I propose here, but one must know what

a) Debug this part of otcl code with my otcl debugger
http://inesc-0.tagus.ist.utl.pt/~pmsrve/ns2/ns2_debugging2.html


and check why code is going into the default case.

Maybe its a bug on the switch

[ns] icmp response in tcp applications

[Marco Bonetti]

Hello everybody!
I'm working with ns-allinone-2.29 on mac osx and writing application
to be run on top of ns nodes, following various tutorials here and
there on the net I came up with some resonable UDP apps (worm-like),
now I'm trying to do that on top of TCP.
I'm thinking that it would be nice to get ICMP response when a nodes
tries to send data to something not existent, but I don't know how I
can do this.

does anyone know where I can start looking for?

thanks in advance,
ciao

  Hello everyone!!
I have a question regarding simulation time in ns-2
I am using ns-2.27 version and i have noticed that the calculated 
throughput in my wireless scenario changes as the simulation time 
increases.What  simulation time should i set to my tcl script in order to 
get
accurate throughput results?

Any point or hint is extremely welcomed
Thanks for your attention!!!

Re: [ns] Problem with installation of NS 2.28

[Filippos Kolovos]

I apologise, in my previous message I forgot to edit
the subject line.:-)



>From the warning messages displayed, you have
installed ns-allinone 2.28, not ns-2.28 (the latter is when
you install it from the pieces). When you install it from the
pieces, it does not display such a warning.

The LD_LIBRARY_PATH is actually an extra
set of directories, where the run-time shared library loader
will look for any needed shared libraries when loading an executable.
You can define multiple directories as the value for that variable separated

with a colon (:)

Specifically, the value of this environment variable (i.e the list of
directories specified)
is added to the beginning of** the existing list of compiled-in loader paths
for a given executable, and any system default loader paths.

You add this environment variable in the startup file of your login shell (
i.e. .bashrc for bash
or .login for tcsh) specifying it as it is shown in the messages.
An example of a specification for the LD_LIBRARY_PATH in one of my
ns-allinone installations is shown below. I have put this variable (among
others) in the .bashrc
file in my home dir:

 export NS_HOME=/home/MIS_USER/ns-allinone-2.26

export LD_LIBRARY_PATH=$NS_HOME/tcl8.3.2/unix:$NS_HOME/tk8.3.2/unix:\
$NS_HOME/otcl-1.0a8:$NS_HOME/lib:$LD_LIBRARY_PATH


Notice that I have put the home dir of ns-allinone in another env var, which
I use
in the specification of the LD_LIBRARY_PATH var.

I Hope to have helped.

P.S.
For further information regarding this variable or its security implications
when using it,

From the warning messages displayed, you have
installed ns-allinone 2.28, not ns-2.28 (the latter is when
you install it from the pieces). When you install it from the
pieces, it does not display such a warning.

The LD_LIBRARY_PATH is actually an extra
set of directories, where the run-time shared library loader
will look for any needed shared libraries when loading an executable.
You can define multiple directories as the value for that variable separated

is added to the beginning of** the existing list of compiled-in loader paths
for a given executable, and any system default loader paths.

You add this environment variable in the startup file of your login shell (
i.e. .bashrc for bash
or .login for tcsh) specifying it as it is shown in the messages.
An example of a specification for the LD_LIBRARY_PATH in one of my
ns-allinone installations is shown below. I have put this variable (among
others) in the .bashrc
file in my home dir:

Re: [ns] where to save .cc files

[Tiago Camilo]

Hi,
perhaps you forgot to insert in the Makefile.in the path to your .cc files...
After this you will need to:
>./configure
>make

Good luck,
