Re: [ns] how to get node_id in classifier.cc in wired network simulation
I think you should put it in the implementation code of the designated protocol
you need to modify it.

Dear Camilla, I didn't use Tracegraph software in details, but if you want to use it, try fellow installtion steps of the package and try to plot some simple example to become more familiar with the package and to understand how to deal with it(how to extract output, how to justify it and...) before starting with your own application.

I am running it on Cygwin on Windows Vista. After running Cygwin, we need to set environment variables before ns2 commands can be run. Alternatively, we can set them in ..bashrc file so that the environment variables for ns2 are automatically set each time when Cygwin is run instead of manually entering them on command line. When I add the environment variables path in .bashrc files, it gives an error when Cygwin starts saying that ns2-allinone-2.33-2.33 not fount. The commands work fine on the Cygwin prompt. Also Cygwin appends an extra 2.33 at the end automatically when giving an error. Here is the code for updating the environment variables in .bashrc file. The first line is which is giving error: export NS_HOME=/home/Owner/ns-allinone-2.33/ export PATH=$NS_HOME/tcl8.4.18/unix:$NS_HOME/tk8.4.18/unix:$NS_HOME/bin:$PATH export LD_LIBRARY_PATH=$NS_HOME/tcl8.4.18/unix:$NS_HOME/tk8.4.18/unix:\ $NS_HOME/otcl-1.13:$NS_HOME/lib:$LD_LIBRARY_PATH export TCL_LIBRARY=$NS_HOME/tcl8.4.18/library On the Cygwin command prompt, we enter the same commands except for the first line which is: export NS_HOME=`pwd` Please tell me if any body faced the similar problem and got it fixed.

Re: [ns] AWK programms
Salam Alikm,
About the first point: there are two type of packets ( Data and Control )
packets. control=request+reply messages. Also I am referring you to see the
NS-2 manual about Packets in NS-2.
About the second: yes
packet_id = $41; 41 column. also try study the output trace file to get more
information
I advise all the beginner into NS-2 to try simple programs and scenarios.

Re: [ns] trace files
Hi, I would like to know that the awk script is for DSR protocol and you can change it to other protocol like AODV, DSDV,etc. Second thing the awk script for wireless channel, if you see at the begining in the TCL configuration file "set opt(chan) Channel/WirelessChannel" so you take care about that, and thers is another configuration like mobility senarios file, mobility model. From my point view I advice you to do some sample examples for wired and wireless environment and try to mixed between them later, I think there are many points will be clear to you, however If I get somthing relevant to your work I will provide you as soon as possible.

I have out.tr then I want to calculate 3 performance metric :
paket delivery ratio, normalized overhead and end to end delay.
I use my awk script to get desire value but I don't know that was not success.
I get this value in my parsing result

recv = 0.00
routingpkts = 682.00
PDF = 0.00
NRL = inf

No. of dropped data (bytes) = 171304
I am attach .tr file in my mail, please help me what's wrong..?
why my recv and PDF = 0.00?
My awk script was wrong? or
can you give me correct calculation with my out2.tr in my attachment ?
What meaning of : NRL = inf

Yes there is, but let me know something unclear to me: what do you mean by
"orient outputs to our files directory other than ns-2x"? , Is you need to
store simulation output file on other location due to limited disk volume.
clear it...
Another thing I advice you to work under linux operating system, it will help
you than windows systems, and it will provide you avarity of tools that assist
you for extracting results from simulation output traces files.
The last thing, fortunatly, I am also work with subjects related to QoS for Ad
Hoc routing protocols, its fine to meet you.

Thank you very much for your help, your scripts are very welcomed as all other
ideas related to the creation of different scenarios for a simulation, I am
working on a QoS -routing in the overlay of internet , I developped two
formulations and I am working on their performance,
do you have an idea on how to orient outputs to our files directory other than
ns-2x,
thanks

I have another idea, try to use a traffic scenario generator tools
"cbrgen.tcl." that is located in the "~/ns-2.28/indep-utils/cmu-scen-gen" to
generate your CBR traffic in a separte file. and link your file within your TCL
scipt. I think this is a good technique, I used it befor. Beside that you can
use AWK or Perl or bash scripts for extracting results form the simulated
output file. So If want to want to test this way I will privide you some
scripts and I will assist you.
About proc I think there is some statement should written in you procedure

Re: [ns] why not response!!!!
I think its possible, you know that there are a header file *.h and an
implementation file *.cc and *.tcl for configuration simulation file
in C++ code use:
Tcl& tcl = Tcl::instance();
tcl.evalc("Any statement written in you TCL configuration file");
const char* tmp = tcl.resultf() ;
int NewVariable= atoi(tmp);
in your tcl file use:
Any statement written in you TCL configuration file 'number'

Mohammed Abu Hajar <[EMAIL PROTECTED]> a écrit :Creating random
traffic-pattern for wireless scenarios
Random traffic connections of TCP and CBR (Constant Bit Rate) can be setup
between mobile nodes using a traffic scenario generator script. This traffic
generator script is available under ~/ns-2.28/indep-utils/cmu-scen-gen and is
called cbrgen.tcl. The command line looks like the following:
ns cbrgen.tcl [-type cbr|tcp] [-nn nodes] [-seed seed] [-mc
connections] [-rate rate]
-type cbr|tcp
Type of the generated traffic, TCP or CBR
-nn nodes
Total number of nodes being simulated
-seed seed
Random number seed used to initialize part of the seed of various randomly
generated numbers in the simulation. This can be used to vary the seed of the
simulation to see the consistency of the results of the simulation
-mc connections
Number of flow connections
-rate rate
Number of packets per second.
cbr gensub-command explanation
The start times for the TCP/CBR connections are randomly generated with a
maximum value set at 180.0s, thus the simulation time is at least 180 seconds,
and the number of nodes has no relationship to the maximum number of
connections.
A typical generated CBR traffic file looks like:
set udp_(1) [new Agent/UDP]
$ns_ attach-agent $node_(4) $udp_(1)
set null_(1) [new Agent/Null]
$ns_ attach-agent $node_(5) $null_(1)
set cbr_(1) [new Application/Traffic/CBR]
$udp_(1) set fid_ 1
$cbr_(1) set packetSize_ 512
$cbr_(1) set interval_ 0.25
$cbr_(1) set random_ 1
$cbr_(1) set maxpkts_ 1
$cbr_(1) attach-agent $udp_(1)
$ns_ connect $udp_(1) $null_(1)
$ns_ at 56.333118917575632 "$cbr_(1) start"
A typical generated TCP (FTP) traffic file looks like:
set tcp_(0) [ new Agent/TCP ]
set sink_(0) [ new Agent/TCPSink ]
set ftp_(0) [ new Application/FTP ]
$tcp_(0) set class_ 1
$tcp_(0) set packetSize_ 512
$ns_ attach-agent $node_(1) $tcp_(0)
$ns_ attach-agent $node_(2) $sink_(0)
$ftp_(0) attach-agent $tcp_(0)
$ns_ connect $tcp_(0) $sink_(0)
$ns_ at 2.5568388786897245 "$ftp_(0) start"
$ns_ at $val(stop) "$ftp_(0) stop"
If you want to change the values you can use awk script to do that.

Re: [ns] Require Awk script for Old Trace Format File
About the awk script for calculate jitter and the awk script for calculate

# Trace line format: normal(for old trace)
if ($2 != "-t") {
event = $1
time = $2
if (event == "+" || event == "-") node_id = $3

About the awk that calculate Packet Delivery Fraction , Normalize routing
load, End to End delay and drop packets and Routing Load(overhead) its valid
for new trace only. So you can modify the parameters used in the awk script
only or when there ia available time I will modfy it for you.
Lastly I advice you to use new trace format using TCL command in your TCL
file :
$ns_ use-newtrace
you will get the trace file in new fashion

Hi manpreet,
In general, a routing protocol is better if the normalized routing load is
low.

Re: [ns] how to get node id in classifier
I understand from your query that you want to know the current execution mobile

From the error message you get, means net_id variable not found(not declare)
so may be the data structure (procedure) you deal with node identification does
not handle , so I advice you to read the structure more times, may the point
will be clear.

Re: [ns] jitter NRL PDF throughput end to end delay
About Normalized Routing Load (NRL) it is
It is the number of routing packet required to be send per data packet
delivered.
NRL = (NumberofRoutingPacket)/(NumberofPacketReceived)
so if you want to change the NRL value you should either change one of the
parametres used in equation, this is done by changing the number of traffic
sources, number of data packet per second or number of mobile nodes in your
simulation scenarion
about the second query , try to see tracegraph analysier, it may help you ,
and I will do some searching through the internet for other relevant
information.

Load variance-routing level,
Squared sum-MAC level,Laod
variance-MAC level,
End-to-end delay,
throughput(in kbps),
Routing Overhead,offered load.
or some references to them, it will be very helpful to me..
If you have calculated any one of the above parameters do help
