[ns] NS2 + UCBT

[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

Re: [ns] Xgraph basic question

[Loreno Oliveira]

If using xgraph is not a need, you may try gnuplot for ploting your
graphs...

[ns] RSSI measurement

[Loreno Oliveira]

Hi All,

does anybody know how do I measure the RSSI between two wireless nodes?? As
far as I have seen in the archive, this question has been posted during
years in this list without any reply. I will be extremelly thankful if
somebody had some hint about it.

Regards,

Loreno

Re: [ns] RSSI measurement

[Loreno Oliveira]

Hi Svilen, thanks for the answer!

I will take a look at the method you said. Regarding your question, yes. I'm
working on a handoff protocol for Bluetooth. An essential point of the
protocol is the constant RSSI measurement between base stations and mobile
devices.

I am working with UCBT, which seems that does not implement RSSI measurement
between nodes. Now I am taking a better look at NS and how UCBT is
integrated to it in order to derive some way of making the RSSI
measurements...

Do you have some experience with modeling of localization experiments?? I
would be great if I could exchange some ideas with someone with some
expertise on this field...

Regards,

Loreno

Re: [ns] R: RSSI measurement

[Loreno Oliveira]

Hi Marco, very thanks to your reply!

I will take a look at the structure you said and doing some tests. Based in
what you said, probably this solves my problem. A priori I am only
considering simpler scenarios where I do not need to deal with
interferences. My actual concern is only finding a way of estimating the
distance between two bluetooth devices, and I thought RSSI was the
straingforward solution...

Loreno

Re: [ns] Problems running simulations

[Loreno Oliveira]

Not sure if this is a ns/nam issue. Imediatelly before/after getting this
message can you open some graphical application, such as xclock??

Re: [ns] ns-allinone-2.29 Installation problem in cygwin

[Loreno Oliveira]

Hi there Aravind!

As the archive is quite big, maybe you have missed my post where I respond
to this question.
Try to look at http://mailman.isi.edu/pipermail/ns-users/2006-October.txt.
Once downloaded, type CTRL + F for searching a pattern and write "Unpack
ns".

This was my answer to a question quite similar to yours. Besides my answer,
there are at least two or three answers in the archive for this same
question. It's all about having time and patience for searching 150MB of
archives :-)

Regards,

Loreno

Re: [ns] voice and video traffic in ns2(help)

[Loreno Oliveira]

Hi Ghazale,

I am also working with simulation of audio and video flows. Well, I may be
wrong in my approach, but all I did was creating a simple CBR traffic
generator over UDP. I have also made some real tests for getting some
parameters for supplying NS2, such as MTU, packet size, and rate.

Of cource, this scenario can vary as our needs are distinct. For instance,
if you are simulating voice transmition for telephony purposes, you propably
should use TCP instead of UDP. Moreover, CBR is apropriate for the set of
applications I am interested in. Maybe the VBR model is better suitable for
your objectives.

Regards,

Loreno

[ns] NS programming

[Loreno Oliveira]

Hi all,

I do not know if this is the right list for asking this. Btw, I have been
studing NS since a few days. Now I have some idea of what I need to do for
creating the scenarios I need. The question is where to start. Does anybody
knows some tutorials/manuals/how-tos regarding the extending of NS? The "NS
by examples" brings an example of how to create a new protocol, and it gives
an idea of the number of details that need to be dealt with in order to put
the things working.

Thanks in advance for any help!

Loreno
