I cant run NetAnim for first.cc

[Miguel Alves]

Hello guys, i am having a problem here.

I did this, and everything was ok:

1. make clean 2. qmake NetAnim.pro 3. make Now your NetAnim is ready to use For adding ns3 to your program, do the following 1. include "ns3/netanim-module.h" 2. Add the following statement before Simulation::Run() AnimationInterface anim ("animation.xml"); 3. Set give positions to your nodes. anim.SetConstantPosition (node, double x, double y);

but, when i open NetAnim i couldnt find my xml file. Do you know why?

You should provide the code you are using on the simulation. Assuming you placed  AnimationInterface anim ("animation.xml"); before Simulation::Run and that you have configured node, their mobility and made a simulation with a duration > 0. You should find a file called "animation.xml" on your ns-3 main directory (ex. ns-3-allinone/ns-3.27)
Then you have to open NetAnim, go to load XML file (little folder icon on top left corner) and choose that file "animation.xml".

Can't help you any further without code.

sry, the code is this one (first.cc) :

#include "ns3/netanim-module.h"
#include "ns3/core-module.h"
#include "ns3/network-module.h"
#include "ns3/internet-module.h"
#include "ns3/point-to-point-module.h"
#include "ns3/applications-module.h"

using namespace ns3;

NS_LOG_COMPONENT_DEFINE ("FirstScriptExample");

int
main (int argc, char *argv[])
{
CommandLine cmd;
cmd.Parse (argc, argv);

Time::SetResolution (Time::NS);
LogComponentEnable ("UdpEchoClientApplication", LOG_LEVEL_INFO);
LogComponentEnable ("UdpEchoServerApplication", LOG_LEVEL_INFO);

NS_LOG_INFO ("Creating Topology");

NodeContainer nodes;
nodes.Create (2);

PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute ("DataRate", StringValue ("5Mbps"));
pointToPoint.SetChannelAttribute ("Delay", StringValue ("2ms"));

NetDeviceContainer devices;
devices = pointToPoint.Install (nodes);

InternetStackHelper stack;
stack.Install (nodes);

Ipv4AddressHelper address;
address.SetBase ("10.1.1.0", "255.255.255.0");

Ipv4InterfaceContainer interfaces = address.Assign (devices);

UdpEchoServerHelper echoServer (9);

ApplicationContainer serverApps = echoServer.Install (nodes.Get (1));
serverApps.Start (Seconds (1.0));
serverApps.Stop (Seconds (10.0));

UdpEchoClientHelper echoClient (interfaces.GetAddress (1), 9);
echoClient.SetAttribute ("MaxPackets", UintegerValue (1));
echoClient.SetAttribute ("Interval", TimeValue (Seconds (1.0)));
echoClient.SetAttribute ("PacketSize", UintegerValue (1024));

ApplicationContainer clientApps = echoClient.Install (nodes.Get (0));
clientApps.Start (Seconds (2.0));
clientApps.Stop (Seconds (10.0));

AnimationInterface anim ("animation.xml");

anim.SetConstantPosition(nodes.Get(0), 1.0, 2.0);
anim.SetConstantPosition(nodes.Get(1), 2.0, 3.0);

Simulator::Run ();
Simulator::Destroy ();
return 0;
}

The xml file doesnt appear in NetAnim, something wrong here?

i didnt configured mobility nodes, but in youtube videos they say it is not impotant for the xml file be created.

[Vitor Lamela]

just ran the code you gave on ns-3 (ns-3-dev) and correctly produced the animation.xml file.

There are warnings because of the mobility model as you can see. But anyways you manually set it on the "anim" variable.
Here I attach the file.

Appart of mobility model the xml file should be created. And i still cant make it appear. Anyway, thanks for the file.
