How To Implement Vehicular NDN In Ns3

To implement a Vehicular Named Data Networking (NDN) in ns-3 by the extension of ns-3 ndnSIM module for simulating NDN networks. We work on all types of modules  so stay on touch with us for more assistance.

Here’s the steps given to setup a basic vehicular NDN simulation in ns-3 uding ndnSIM;

Step-by-Step Guide to Implement Vehicular NDN in ns-3

1. Set Up Your Development Environment

1. Install ns-3:
   • Follow the official ns-3 installation guide.
2. Install ndnSIM:
   • Follow the ndnSIM installation guide.

# Clone ndnSIM and ns-3

git clone https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3

cd ns-3

git clone https://github.com/named-data-ndnSIM/ndnSIM.git

# Build ndnSIM

./waf configure -d optimized

./waf

2. Create a Basic Vehicular NDN Simulation Script

An example script given  to set up a basic Vehicular NDN scenario using ndnSIM:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/mobility-module.h”

#include “ns3/ndnSIM-module.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE(“VehicularNDN”);

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

  // Set default parameters for the simulation

  CommandLine cmd;

  cmd.Parse(argc, argv);

  // Create a container for the vehicles

  NodeContainer vehicles;

  vehicles.Create(3);

  // Set up mobility model for the vehicles

  MobilityHelper mobility;

  mobility.SetMobilityModel(“ns3::ConstantVelocityMobilityModel”);

  mobility.Install(vehicles);

  // Set initial positions and velocities for the vehicles

  Ptr<ConstantVelocityMobilityModel> mobilityModel;

  mobilityModel = vehicles.Get(0)->GetObject<ConstantVelocityMobilityModel>();

  mobilityModel->SetPosition(Vector(0, 0, 0));

  mobilityModel->SetVelocity(Vector(20, 0, 0));

  mobilityModel = vehicles.Get(1)->GetObject<ConstantVelocityMobilityModel>();

  mobilityModel->SetPosition(Vector(50, 0, 0));

  mobilityModel->SetVelocity(Vector(20, 0, 0));

  mobilityModel = vehicles.Get(2)->GetObject<ConstantVelocityMobilityModel>();

  mobilityModel->SetPosition(Vector(100, 0, 0));

  mobilityModel->SetVelocity(Vector(20, 0, 0));

  // Install NDN stack on the vehicles

  ndn::StackHelper ndnHelper;

  ndnHelper.InstallAll();

  // Set up NDN forwarding strategy

  ndn::StrategyChoiceHelper::InstallAll(“/”, “/localhost/nfd/strategy/multicast”);

  // Set up NDN applications

  // Consumer application on the first vehicle

  ndn::AppHelper consumerHelper(“ns3::ndn::ConsumerCbr”);

  consumerHelper.SetPrefix(“/prefix”);

  consumerHelper.SetAttribute(“Frequency”, StringValue(“10”)); // 10 interests per second

  consumerHelper.Install(vehicles.Get(0));

  // Producer application on the last vehicle

  ndn::AppHelper producerHelper(“ns3::ndn::Producer”);

  producerHelper.SetPrefix(“/prefix”);

  producerHelper.SetAttribute(“PayloadSize”, StringValue(“1024”));

  producerHelper.Install(vehicles.Get(2));

  // Run the simulation

  Simulator::Stop(Seconds(10.0));

  Simulator::Run();

  Simulator::Destroy();

  return 0;

}

Explanation of the Script

Here we have discussed about the important process of implementing vehicular NDN in ns-3:

1. Include Necessary Headers:
   • Include headers for ns-3 core, network, internet, mobility, and ndnSIM modules.
2. Set Default Parameters:
   • Define command-line arguments and set default parameters for the simulation.
3. Create Vehicles:
   • Create a container for the vehicles.
4. Set Up Mobility Model:
   • Set up the mobility model for the vehicles using MobilityHelper and ConstantVelocityMobilityModel.
5. Set Initial Positions and Velocities:
   • Set initial positions and velocities for the vehicles to simulate movement.
6. Install NDN Stack:
   • Install the NDN stack on the vehicles using ndn::StackHelper.
7. Set Up NDN Forwarding Strategy:
   • Install a multicast forwarding strategy on all nodes using ndn::StrategyChoiceHelper.
8. Install NDN Applications:
   • Install a consumer application on the first vehicle and a producer application on the last vehicle.
9. Run the Simulation:
   • Set the simulation stop time, run the simulation, and clean up using Simulator::Stop, Simulator::Run, and Simulator::Destroy.

Further Enhancements

1. Advanced Mobility Models:
   • Implement more realistic mobility models, such as the Manhattan mobility model or models based on real vehicular traces.
2. Routing Protocols:
   • Implement and evaluate different NDN forwarding strategies or routing protocols.
3. Network Performance Metrics:
   • Collect and analyze performance metrics such as data retrieval time, hop count, and network overhead.
4. Applications:
   • Implement more complex applications and communication patterns, such as video streaming or cooperative sensing.
5. Interference Modeling:
   • Model interference and evaluate its impact on network performance.
6. Fault Tolerance and Resilience:
   • Implement and evaluate fault tolerance mechanisms and resilience strategies for vehicular communication.

      Finally, we all get know how the Vehicular NDN is implemented in ns-3 environment. System development  on any area of Vehicular NDN are carried out by us.
