I am new in ns3..can u please explain how the RandomWalk2dMobilityModel works? I am trying to model an environment where a user will be given a destination and he want to go there using a random speed. Is this possible to design with this model?

Thank You

static void 
CourseChange (std::string foo, Ptr<const MobilityModel> mobility)
{
  Vector pos = mobility->GetPosition ();
  Vector vel = mobility->GetVelocity ();
  std::cout << Simulator::Now () << ", model=" << mobility << ", POS: x=" << pos.x << ", y=" << pos.y
            << ", z=" << pos.z << "; VEL:" << vel.x << ", y=" << vel.y
            << ", z=" << vel.z << std::endl;
}

int main (int argc, char *argv[])
{
  Config::SetDefault ("ns3::RandomWalk2dMobilityModel::Mode", StringValue ("Time"));
  Config::SetDefault ("ns3::RandomWalk2dMobilityModel::Time", StringValue ("2s"));
  Config::SetDefault ("ns3::RandomWalk2dMobilityModel::Speed", StringValue ("ns3::ConstantRandomVariable[Constant=1.0]"));
  Config::SetDefault ("ns3::RandomWalk2dMobilityModel::Bounds", StringValue ("0|200|0|200"));

  CommandLine cmd;
  cmd.Parse (argc, argv);

  NodeContainer c;
  c.Create (100);

  MobilityHelper mobility;
  mobility.SetPositionAllocator ("ns3::RandomDiscPositionAllocator",
                                 "X", StringValue ("100.0"),
                                 "Y", StringValue ("100.0"),
                                 "Rho", StringValue ("ns3::UniformRandomVariable[Min=0|Max=30]"));
  mobility.SetMobilityModel ("ns3::RandomWalk2dMobilityModel",
                             "Mode", StringValue ("Time"),
                             "Time", StringValue ("2s"),
                             "Speed", StringValue ("ns3::ConstantRandomVariable[Constant=1.0]"),
                             "Bounds", StringValue ("0|200|0|200"));
  mobility.InstallAll ();
  Config::Connect ("/NodeList/*/$ns3::MobilityModel/CourseChange",
                   MakeCallback (&CourseChange));
