How to implement DSDV protocol in ns3

To implement the destination-sequenced-distance-vector (DSDV) protocol in ns3 consists by using the DSDV. Here are the step by step procedures to implement the DSDV protocol in ns-3.

Step-by-Step Implementation

  1. Set Up Your Environment

Make sure ns3 is installed. If not installed then download it from official website.

  1. Create a New ns-3 Script

Create a new simulation script in the scratch directory of your ns-3 installation. For example, you can create a file named dsdv-simulation.cc.

cd ns-3.xx

cd scratch

touch dsdv-simulation.cc

3.      Include Necessary Headers

In your dsdv-simulation.cc file, include the necessary headers for your simulation.

#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”

#include “ns3/dsdv-module.h”

 

using namespace ns3;

4.      Set Up the Network Topology

Define the network topology. For simplicity, let’s create a basic topology with three nodes connected in a line.

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

{

  CommandLine cmd;

  cmd.Parse (argc, argv);

  NodeContainer nodes;

  nodes.Create (3);

  PointToPointHelper pointToPoint;

  pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));

  pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));

  NetDeviceContainer devices;

  devices = pointToPoint.Install (nodes.Get (0), nodes.Get (1));

  devices.Add (pointToPoint.Install (nodes.Get (1), nodes.Get (2)));

  InternetStackHelper stack;

  DsdvHelper dsdv;

  // Install the DSDV routing protocol on all nodes

  stack.SetRoutingHelper (dsdv);

  stack.Install (nodes);

  Ipv4AddressHelper address;

  address.SetBase (“10.1.1.0”, “255.255.255.0”);

  Ipv4InterfaceContainer interfaces = address.Assign (devices.Get (0));

  interfaces.Add (address.Assign (devices.Get (1)));

  address.SetBase (“10.1.2.0”, “255.255.255.0”);

  interfaces.Add (address.Assign (devices.Get (2)));

  // Set up applications (e.g., a UDP echo server and client) if needed

  Simulator::Run ();

  Simulator::Destroy ();

  return 0;

}

5.      Configure the DSDV Protocol

In this example, the DSDV protocol is installed and configured using the DsdvHelper class. The DsdvHelper class configures the DSDV routing protocol on the nodes.

6.      Build and Run the Simulation

After writing your script, you need to build and run it.

./waf build

./waf –run scratch/dsdv-simulation

7.      Analyze the Results

After running the simulation, you can analyze the results based on your needs. You may want to add logging or tracing to observe the behavior of the DSDV protocol.

Example Script

The given below is the sample script to complete the DSDV protocol:

#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”

#include “ns3/dsdv-module.h”

using namespace ns3;

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

{

  CommandLine cmd;

  cmd.Parse (argc, argv);

  NodeContainer nodes;

  nodes.Create (3);

  PointToPointHelper pointToPoint;

  pointToPoint.SetDeviceAttribute (“DataRate”, StringValue (“5Mbps”));

  pointToPoint.SetChannelAttribute (“Delay”, StringValue (“2ms”));

  NetDeviceContainer devices;

  devices = pointToPoint.Install (nodes.Get (0), nodes.Get (1));

  devices.Add (pointToPoint.Install (nodes.Get (1), nodes.Get (2)));

  InternetStackHelper stack;

  DsdvHelper dsdv;

  // Install the DSDV routing protocol on all nodes

  stack.SetRoutingHelper (dsdv);

  stack.Install (nodes);

  Ipv4AddressHelper address;

  address.SetBase (“10.1.1.0”, “255.255.255.0”);

  Ipv4InterfaceContainer interfaces = address.Assign (devices.Get (0));

  interfaces.Add (address.Assign (devices.Get (1)));

  address.SetBase (“10.1.2.0”, “255.255.255.0”);

  interfaces.Add (address.Assign (devices.Get (2)));

  // Set up applications (e.g., a UDP echo server and client) if needed

  Simulator::Run ();

  Simulator::Destroy ();

  return 0;

}
