Hi,

To view them in NetAmin, you open NetAnim, select the second tab (Stats), in the drop-down menu on the left you select FlowMonitor and then you open your FlowMonitor file.

However, there are 2 other ways to view your results. 

1) Use the flowmon-parse-results.py script which exists in FlowMonitor examples folder

2) Parse the results within your scenario script without the need to create an xml file like this

If you search the mailing list you can find more discussions about FlowMonitor.

hi sir

thanx for reply

when i open flowmonitor file (xml) in NetAnim as u have mentioned above ..nothing happens ..one message is being displayed .." No info available did you load xml file ".

Regards

Open flowmonitor file with any text_editor (it is just an .xml file) and see if there are entries or your file is empty.

You have to create the flowmonitor and install it on the nodes before the Simulator::Run and serialize to the .xml file AFTER the Run().

sir 

 .xml file has following contents 

<FlowMonitor>

  <FlowStats>

  </FlowStats>

  <Ipv4FlowClassifier>

  </Ipv4FlowClassifier>

  <FlowProbes>

    <FlowProbe index="0">

    </FlowProbe>

    <FlowProbe index="1">

    </FlowProbe>

    <FlowProbe index="2">

    </FlowProbe>

    <FlowProbe index="3">

  </FlowProbes>

</FlowMonitor>

when i open it in Netanim from stat tab (selected flow-Monitor from drop down menu and then FlowMon file )

same message of "No data available did you load xml file" is being shown and progress bar of parsing complete is moving side to side 

sir also tell other way of doing  result analysis from trace file etc. as i want to measure various Qos parameters for various protocols in ad hoc networks ..sir do you know how to make a node in DSR protocol to drop packets 

PLz help me 

 thanks '

Regards

sir 

i am writing this code 

Simulator::Stop (Seconds (TotalTime));

FlowMonitorHelper flowmon;

Ptr<FlowMonitor> monitor = flowmon.InstallAll();

NS_LOG_INFO ("Run Simulation.");

  

  Simulator::Run ();

monitor->SerializeToXmlFile ("flownrew.xml", true, true);

  Simulator::Destroy ();

}

Obviously your FlowMonitor xml file is empty. There are not entries. Correctly NetAnim says that.

Most likely you have done the SerialzeToXml before the Run(), that's why your file is empty.

If you read the documentation/wiki/mailing list you can find how you can create/parse/analyse trace file in NS-3.

For explicitly dropping packets, you have to go in the source code of the routing protocol and do not 'forward' the packet to the next node/layer. So it will be seen as dropped.
