Re: [ns] Genrating graphs from trace file generated by OLSR ( tracegraph)
Dear Sasi,
I used tracegraph some time ago, but I found it inefficient and sometimes
gives misleading results. Therefore I do not use it anymore. Instead, I
wrote my own code to calculate many parameters: packet delivery ratio,
normalized throughput, routing overhead ratio, end2end delay, hop count and
connection time. Furthermore, this code is suitable in case you want to
repeat your simulation experiment many times to take the average of them.
This code is freely available and you can download it from the following
link:
(
http://www.ikt.uni-hannover.de/fileadmin/institut/mitarbeiter/bali/pl-sim-1.
1.zip )
NOTE: Be sure to include all text between '(' and ')' when navigating to
this code location!
There is a text file that explains how to use the code. However, I wrote
this code for my own use and for my specific scenario. Therefore, I
encourage you to write your own code because this is the only way to obtain
what you need.
Best Regards,
Samer

Subject: Genrating graphs from trace file generated by OLSR ( tracegraph)
Hi
I am comparing AODV and OLSR protocols.I just attached the three files
which I implemented for both AODV and OLSR. I am sending the traffic and
mobility scenarios. For comparison of different adhoc routing protocols the
tcl file remains same except I am just changing the value of adhocRouting
variable as AODV/OLSR/DSR, etc and calculating the results.Then when
calculating for AODV I just put adhocRouting variable as AODV and run the
simulation and got the trace files from which I generated the output
successfully using tracegraph.
Well did the same for OLSR. successful in simulation and generating the
trace files but can't get graphs from the tracefiles generated by it using
tracegraph. It is giving messages like converting nodes to ip saving in
*.tr.ip file messages.Can you check if it happens to you also? What should
I do to get the graphs for OLSR protocol from trace files? Please let me
know if I have to do something with tcl code or some thing else.
Thanks and regards.
sasi.
[ns] which routing protocol is used in real ad hoc network
When we are creating ad hoc network (tools such as in windows) to make peer to peer network, which type of routing protocol (DSR,AODV, DSDV, etc...) are actually using? Is it true that in Windows they does not do any routing in ad-hoc mode. So what is the purpose of other routing protocol in ad hoc network (DSR, AODV, DSDV, DYMO, etc...). as we know this protocol is good and people always enhanced it. some of them are using multipath to distributed traffic load (sound good). Why they not implement it in real situation? My system : FC 6 2.6.18-1.2869.fc6 ns2.30 - Get easy, one-click access to your favorites. Make Yahoo! your homepage.

thanks; but if the procedure which is changing values in priority.tcl is given a new call using $ns_ at 5.0 DO BLAH; it means probably another instance of the bind object, and hence probably another call to the EDCA object in C++...NO ADAPTATION PROBABLY...?? regards Basim On 11/27/07, Claus Christmann [EMAIL PROTECTED] wrote: Please see inline below: Basim Javed wrote: Hi dear all 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 holds values for some parameters of 4 priority queues of EDCA: I need to change these values dynamically during the run time of EDCA...please guide me how I can do so?

[ns] multicast routing algorithms
Hi!! I have to doy my End's Career Proyect working with ns2 and I'm new on it. My tutor wants me to test some multicast routing algorithms: the Floyd-Warshall algorithm and the Kompella one. I've been looking for information and i've seen the first one is implemented in some way on ns but for mobile agents (god.cc). Can i use it with non-mobile agents too in my simulations?? Is there any extension for ns-2 that implements any of these algorithms?? Thank you very much for any help you can provide me :). Pablo
Re: [ns] Ns-users Digest, Vol 47, Issue 25
Hi Folks!
Is there anyone who runs LEACH or any other Mac/routing protocl
successfully in NS-2? Can you provide me code and necessary suggestions?
Thanks in advance.

Dear all
I am a newbie in NS2. I need an urgent help regarding;
1- I found many main() in C++ code, although I was expecting only one,
which would control the whole NS - what does this mean?
2- Apparently 802.11e is not part of NS 2.31, and there is code
available at some sites. How should I fit that separate code into the
big NS 2.31; place of keeping it; recompiling steps etc?
3- Any help specifically to change the parameter set of EDCA, during
start of superframes? How to do it, and any code available?
4- Do I need to understand the class hierarchy of NS 2.31 in order to
run it after modifying or adding some code of my own? where to put
that added code?
steps involved?
I would highly appreciate any help (even related to 802.11 context).
Thank you very much.
kind regards

hello Basim,
plz provide information about the patch and web link so some can help.
on the other hand you should have the instructions along with the patch
file to use it with NS.
regards,

Very urgent for me.

Be a better pen pal. Text or chat with friends inside Yahoo! Mail. See
how.
This is just an example awk script to calculate Throughput. It may help
you.
BEGIN {
ue1_throughput=0;
}
{
if($1==r $4==2 $5==tcp $8 == 0)
{
ue1_throughput = ue1_throughput + $6 - 40;
}
}
END {
print Throughputs for each user equipment -
print Total throughput achieved by UE1:
(ue1_throughput/10)*(8/1000) kbps;
print End of Results;
}
