How to Start Tutorials point Routing Projects Using NS3

To start a routing project using NS3 according to the tutorials point concepts or same tutorials, we adhere to this detailed procedure:

Steps to Start Tutorialspoint Routing Projects in NS3

  1. Install and Set Up NS3
  • Initially, we make sure that NS3 is correctly installed.

sudo apt update

sudo apt install g++ python3 git cmake

git clone https://gitlab.com/nsnam/ns-3-dev.git

cd ns-3-dev

./waf configure

./waf build

  1. Learn NS3 Basics
  • We learn basics from NS3 tutorials.
  • Discover example codes within the examples or folder, particularly in examples/routing.
  1. Understand Routing Concepts
  • Look at kinds of routing that are utilized in NS3:
    • Static routing
    • Dynamic routing like AODV, OLSR, and DSR
  • For example, to configure static routes within a network manually.
  1. Basic NS3 Routing Project
  • Configure a simple network topology:
    • Make nodes and links.
    • Allocate an IP addresses.
    • Then, configure a routing protocol.

Example Code (Static Routing):

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

using namespace ns3;

int main() {

NodeContainer nodes;

nodes.Create(3); // Create 3 nodes

PointToPointHelper pointToPoint;

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

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

NetDeviceContainer devices;

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

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

InternetStackHelper stack;

stack.Install(nodes);

Ipv4AddressHelper address;

address.SetBase(“10.0.0.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces = address.Assign(devices);

Ptr<Ipv4StaticRouting> staticRouting = Ipv4RoutingHelper::GetStaticRouting(nodes.Get(0)->GetObject<Ipv4>());

staticRouting->AddHostRouteTo(Ipv4Address(“10.0.0.2”), Ipv4Address(“10.0.0.1”), 1);

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Dynamic Routing Protocols
  • We can utilize inherent dynamic routing protocols such as AODV, OLSR, or we make custom protocol.

Example (AODV Routing):

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/aodv-helper.h”

using namespace ns3;

int main() {

NodeContainer nodes;

nodes.Create(4);

InternetStackHelper stack;

AodvHelper aodv;

stack.SetRoutingHelper(aodv);

stack.Install(nodes);

// Set up the rest of the topology, channels, and addresses…

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Simulate and Analyze
  • For in-depth analysis, we need to utilize trace files (.pcap) or logging:

./waf –run your-project-name

  • We envision the outcomes using tools such as Wireshark, Python, or MATLAB.

Overall, we had absorbed the NS3 basics, routing concepts and projects for Tutorialpoint Routing Projects that were simulated and analysed using above given method with example coding in NS3 simulation platform. We are ready to expand it further as required.
