hi all
I am new to NS2 world, and just recently installed NS 2.31. I would really
appreciate help regarding comparison of xgraph and gnuplot, regarding their
strengths and weaknesses.
Thank you in advance.

Hi all
I need data to plot throughput at 802.11e. Could somebody guide which of the
two approaches would be better:
1. write a C++ code which can generate an output file, to be picked by
gnuplot
2. somehow generate MAC level trace file using traceall (if such thing is
possible at MAC level), pos
Dear all
I am new to the NS2 world. Could any one guide me if I can change the
parameter set values of 802.11e at the start of each Superframe, in the
available implementation of NS2.
I would really appreaciate your support and detailed reply.
Thank you.
kind regards

How can I make a trace file which can be processed to find out the
802.11eMAC level throughput? Is there another way?

dear all
an urgent help needed: can anybody comment on using AWK & PERL for NS2 trace
files, regarding ease of thier usage, and finding relevant scripts for
802.11e and TCP for both?
thanks a lot.

I am using NS2.31 and EDCA patch of TU Berlin (EDCA_ns-2_28-v1-0-2.tgz)
Within this EDCA patch, there is one patch file called priority.tcl and it

hi all
I have a very urgent and desperate call for help. I am using NS2-31 and EDCA
patch of TU Berlin, for 802.11e. Please guide me how to:
1. get the MAC level throughput trace file (the TCL code etc.)
2. how I can evaluate the behaviour of H.264 over NS2 for some video frames.

hello all
Somebody might like to respond to this urgent call to understand error
conditions over a WLAN channel. I need to have your point of views on
the statement:
"Are channel conditions entirely summarized in error rates? "
waiting for your responses...thanks

dear all
while using the error model in WLAN, how can one know that an error has
actually occured at a particular time. Is there some event triggered when an
error occurs?
any comments are needed.

Dear All
I am trying to do some NS2 simulations for EDCA (IEEE 80-2.11e). Do you have
some TCL scripts for throughput, reliability, delay etc... Also how can we
control running of the EDCA using AKAROA...any tutorial on AKAROA?
I am in urgent need please.
thanks

Dear all
my question is regarding NS-2.31 and TU Berlin EDCA for 802.11e. There is
one file priority.tcl in it. If we change the values of some of QoS
parameters in it, then we need to re make NS. Is there some way that we can
change them while the simulation is running, and the change is propaga

hello
could some body help me. I am running the code:
set q [new Queue/DTail/PriQ]
$q set Prio 0 PF 2
puts "one [$q set Prio]"

and expect the output of two to be: two 2, but it gives 0.
could u plz point out where I am doing the mistake?
thanks many

I am using ns 2.31 and TKN EDCA patch for 802.11e. I need to set and

hello 802.11e experts
Could somebody shed some light as why getting some help on TKN EDCA
802.11e is almost not possible over this list.
Would somebody kindly give some pointers about the following issues:
1. new trace format does not contain the time stamp for EDCA. Is it
due to the lack of imp
I think its the MAC rate(s) used for calculating the Tx time of a packet.
Yes the header is sent at basic rate always, to overcome the sync issue at
all.
Well for PHY, I think it should only be related for PHY calculations as per
the modulation used. So different PHY rates enable different MAC ra
Hello
Is there some way to activate multiple channels for 802.11? e.g. two single
hop networks operating nearby to each other will impact each other's
performance, or even a microwave oven can be considered to be one of the
channel, and it will interfere with some nodes nearby. How can we get the
