[ns] ns2 mannasim scriptgenerator directed diffusion error

[antonis antoniou]

Hi all i tested directed diffusion using scriptGeneratorTool of mannasim and 
the resulted tcl script gives me the folowing error.
can anyone help me to correct it?

[ns] solaris patch for ns-2.28

[César Cárdenas]

Dear all,
In the solaris patch for ns-2.28 the directories have the termination name
of "-2.27":

http://www.isi.edu/nsnam/dist/solaris.patch

Do I must change this patch file, specifically write 2.28 instead of 2.27?
Do I must follow the following procedure in order to install ns-2.28: decompress
ns-allinone-2.28.tar.gz, run the patch, then install ns-2.28?

Thanks for any reply, kind regards,
César

[ns] Throughput measurements AGT level-NS2

[Shaili Desai]

Hello ppl

While  I am trying to calculate throughput of CBR traffic, for some script I
am getting no packets sent between source node and destination node at AGT
level. I have known that to calculate throughput it should be done at AGT
level,is htat correct understanding?
It doesnt give the right analysis by calculating it at RTR level correct?
Can anyone confirm this to me,that to calculate throughput,delay and jitter
kinda parameters using AWK script,I need to calculate it at AGT level?

THanks in advance.

Re: [ns] Multi-interface support howto

[Ramon Aguero]

Hello Laurent, Nguyen, all,

Thanks for the discussion.

In my opinion, it's sort of difficult to compare both approaches. It seems 
that the work that Laurent has done is quite much more comprehensive and 
detailed, since it uses a different approach from what the current ns-2 
architecture uses for wireless networks. I've read the document (more 
comments/feedback to come), but I do really find it an interesting piece of 
work.

I'll upgrade our howto to cite it, and sorry for not having done it before. 
We were not aware of it; in fact in this new version I'll also cite the 
Miracle work; these two, which also address the multi-channel problematic, 
use different approaches than we do, and that's one of the reasons for not 
citing them.

Now let me try to provide some inline comments about what Laurent said 
about our howto. I know that its scope is probably not too broad, but what 
we tried (as we had already said) is to make something to help people. I 
know that there were some other sources of information (and thus all of 
them are cited/referenced in our howto), but we still believed (due to the 
number of questions on the mailing list and our personal experience with 
such information), that there was something else that could be done.

This is true, although my understanding is that this is due to the fact 
that there are not really many other choices, I'm pretty sure that this 
could be changed quite quickly. However, I fail to see a use case for this. 
In ad hoc routing environments (which were the main thing we had in mind), 
the typical case is to have different interfaces IEEE 802.11a/b/g, even 
bluetooth, under the same routing protocol, I think that this is 
achievable. In fact, something we can already do is to tweak the parameters 
of any of the PHY/MAC layers, so that we can mimic 802.11b and 802.11g 
working together (changing the energy, the transmission range, etc).

On the other hand, if, e.g. you are using a WSN (with some dual 
802.15.4/802.11 nodes), having more than one routing protocol would make 
sense to me.

Well, the main reason behind this was that most of the people developing 
new routing protocols for ns-2 are doing it using the MobileNode. There is 
more documentation, and I really believed (having personally worked with 
the SRNode one) that it's much simpler.

I can't completely agree with you here. As it is stated in the howto, we 
have undertaken different changes:
- In the Hyacinth work, (and the corresponding updates), all nodes need to 
have the same number of interfaces, which is fixed. We provide a way to 
make this as flexible as the user wants, and in fact, we also maintain the 
original behavior of the simulator, so that people can still use their 
original scripts.
- This flexibility allows, not only modifying the number of channels 
(either at the scenario or at the node level), but to establish to which 
channels the node needs to connect to.
- One of the most important aspects is that the existing information didn't 
tackle how to modify existing routing routing protocols, and we also tackle 
this in the howto.

Best regards,
Ramón 

[ns] BaseStation coverage area.

How can I define BaseStation node coverage area?

Re: [ns] [ns-users] problem in sensing range

[Matthias Budde]

As far as I know is what you wrote incorrect. It is possible to just use the
free space model as a propagation model. Your description is accurate for
the two ray ground model, which is composed of two formulas, first the
same as with the free space model (Friis' transmission equation) and after 
the crossover distance another (dating back to Rappaport).  

When setting the propagation model to free space you should be able to
derive your settings from the following equation (taken from threshold.cc):

   Pt * Gt * Gr * (lambda²)
P =  --
 (4*pi * d)² * L

with:

P Recieving Threshold (RXThresh)
Pt Transmission Power
Gr Antenna reciving gain
Gt Antenna transmission gain
lambda wavelength (= 3.0e08 / frequency)
d distance
L System Loss

Best,

-Matt

[ns] RTP implementation in ns2

[GEORGIOS KIOUMOURTZIS]

Hello to all the ns2 users
I was struggling to find a solution to run rtp-simple.tcl. It gives erros
concerning the dst_addr_. So, I made a a small modification to the ns-2.30
/tcl/rtp/session-rtp.tcl.
Then I recompiled ns-2.30 .
It seems it works properly now but I need users' feedback.
I you are working in multimedia transmission with RTP/RTCP and multicasting
send an email to give you the code for session-rtp.tcl
and let us share knowledge.
I also discuver I thing some bugs in rtp and I'd like to discuss them with
those who are interested in.
best regards
