Re: [ns] UMTS on NS-2
Hi!
Did you remember to recompile ns-2, as the instructions imply?
Best wishes,

I recently installed ns-2.30 and added the required eurane patch to run UMTS on
it, however when i try to run the test_tcp.tcl file or any other file i get the
following error:
any suggestions as to why this is happening?

Hi!
First of all, please post your questions to the mailing list. It adds
value to the list.
Yes, you can have multiple versions of ns running in parallel, but you
need to be very careful how you set up your paths. Please search the web
for setting up paths in the shell. That will search your other problems
you wrote about.
Best regards,

Dear Mats,
Please advise me, can I have both NS-2.33 and NS-2.30 at the same
time? Will they both ok if they coexist or do I need to get rid of
one for th other?
Thanks a lot in anticipation

Hello!
Reference to my previous email about UMTS implementation on NS-2. Can
some one tell me if I need a separate patch for UMTS while working on
NS-2.33? If so, where can I download it from? I have seen
http://eurane.ti-wmc.nl/eurane/, patch available there is in diff.gz
format. I am a newbie to open suse linux, I think I should be after
something .tar.gz?
There is currently no patch for ns-2.33 and since Eurane is not
supported anymore, there probably never will be. You have two
options. 1) Download ns-2.30 and patch with existing eurane patch. If
you need something introduced in later versions of ns-2, you cannot
use it. 2) Patch an existing ns-2.33 with the eurane patch for
ns-2.30. This could result in difficulties which you must manually
resolve.
The patching procedure is documented in the manual, section 2.3.
A patch is distributed in something called a diff-file, hence the
file extension .diff. Gzip then adds the extension .gz. Before
pathing the .diff.gz file needs to be uncompressed using gunzip. The
result will be the diff-file.
Anyway, when I download and open eurane1.12.diff.gz, it gives an
error associated help application does not exist! This patch is
available for NS-2.30, I am using 2.33.
What gives an error? A patch file should not be opened, see the
eurane manual for correct usage, or the patch man page, or google for
unix command patch or similar.
Also, what is CLEAN NS-2.3
A clean version is a version not messed up by changes, builds etc. A
fresh downloaded version is a clean version.
I downloaded test_tcp.tcl (UMTS implementation on NS-2 test run),
without installing any patch on my existing NS-2.33. When I execute
it, it says
(_o3 cmd line 1)
invoked from within
_o3 cmd create-Umtsnode
.
.
.
$ns create-Umtsnode
invoked from within
set rnc [$ns create-Umtsnode]
file umtstcp.tcl line 42
This is because ns-2 (without the patch) does not understand the
instructions in those tcl files. You need the patch to be able to run
the tcl files.

Re: [ns] awk script for calculating end to end delay in a wired-wireless scenario
hi,
Because of inconsistencies in the trace format, sometimes the node id
is given in a hierarchical way (eg, 0.0.1) and other times in a
decimal way (hierarchical addresses normally allocate bits as
10.11.11, so 1.0.1 becomes 4194305). It's generally simplest to have a
look through your trace file and figure out which id is being given to
which node under which circumstances. (eg., sending from a wired node
to a wired node seems to result in hierarchical addresses, but
receiving at a wireless node seems to result in the confusing decimal
format). Here's what I use for calculating loss, it should get you
started and make calculating throughput and delay easier.
#
#Hierarchical routing is used with bits allocated as 10.11.11, #
#addresses must be converted#
#0.0.0 = 0 (our server node) #
#1.0.0 = 4194304(our Access point node) #
#1.0.1 = 4194305(our destination node) #
#
BEGIN{totaltime=input;}
/^+/ /0.0.0.0/ /1.0.1.0/ /Multimedia/{
wtimefield=2
wpacketidfield=12
loss[int($wtimefield)]++;
packet[$wpacketidfield]=1;
}
/^r/ / -Is 0.0/ / -Id 4194305.0/ /AGT/ /Multimedia/ {
if(timefield==0 ||packetidfield==0) {
for(i=1; i=NF; i++) {
if($i==-t)
timefield=i+1;
if($i==-Ii)
packetidfield=i+1;
}
}
loss[int($timefield)]--;
packet[$packetidfield] = 0;
}
END{
for(i=0;itotaltime;i++)
print i loss[i]*1000*8;
}

hello,
does anyone have the awk script to calculate delay,throughput,packet loss in
a mixed scenario i.e. wired-wireless scenario?
i will really appreciate it.
