Move entire "dumbbell" at a constant speed

[RedNumberOne]

I'm trying to move the dumbbell generated by this code at a constant speed. I'm not sure what to do next as whenever I add anything related to SetPositionAllocator or SetMobilityModel, all the node appear at a single point.

#include <iostream>

#include "ns3/core-module.h"

#include "ns3/network-module.h"

#include "ns3/internet-module.h"

#include "ns3/point-to-point-module.h"

#include "ns3/netanim-module.h"

#include "ns3/applications-module.h"

#include "ns3/point-to-point-layout-module.h"

#include "ns3/mobility-module.h"

using namespace ns3;

int main (int argc, char *argv[])

{

  uint32_t    nLeftLeaf = 5;

 uint32_t    nRightLeaf = 5;

 uint32_t    nLeaf = 0; // If non-zero, number of both left and right

 std::string animFile = "dumbbell-animation.xml" ;  // Name of file for animation output

  CommandLine cmd;

 cmd.AddValue ("nLeftLeaf", "Number of left side leaf nodes", nLeftLeaf);

 cmd.AddValue ("nRightLeaf","Number of right side leaf nodes", nRightLeaf);

 cmd.AddValue ("nLeaf",     "Number of left and right side leaf nodes", nLeaf);

 cmd.AddValue ("animFile",  "File Name for Animation Output", animFile);

  cmd.Parse (argc,argv);

 if (nLeaf > 0)

   {

     nLeftLeaf = nLeaf;

     nRightLeaf = nLeaf;

   }

  // Create the point-to-point link helpers

 PointToPointHelper pointToPointRouter;

 PointToPointHelper pointToPointLeaf;

  PointToPointDumbbellHelper d (nLeftLeaf, pointToPointLeaf,

                               nRightLeaf, pointToPointLeaf,

                               pointToPointRouter);

  // Set the bounding box for animation

 d.BoundingBox (1, 1, 100, 100);

  // Create the animation object and configure for specified output

 AnimationInterface anim (animFile);

 

 Simulator::Stop (Seconds (100.0));

 

 Simulator::Run ();

 std::cout << "Animation Trace file created:" << animFile.c_str ()<< std::endl;

 Simulator::Destroy ();

 return 0;

}

Look at the HierarchicalMobilityModel.
