Execution doesn't show results

[saleh refaai]

hello 
I have the attached topology. I am trying to to apply it in NS3 but the results are zeros. Can you help me to know what is missing about the code or if the code even meets the topology. I want it to be somehow similar to the implementation of second.cc code :

#include "ns3/core-module.h"
#include "ns3/network-module.h"
#include "ns3/internet-module.h"
#include "ns3/point-to-point-module.h"
#include "ns3/csma-module.h"
#include "ns3/applications-module.h"
#include "ns3/ipv4-global-routing-helper.h"
#include "ns3/flow-monitor-module.h"

using namespace ns3;

  // Populate routing tables

  // Create applications
  uint16_t port = 9;

// Create and install UdpEchoServer application
  uint16_t port = 9;
