How to Start RIP Protocol Projects Using NS3

To start with a RIP (Routing Information Protocol) project in NS3, we will want being understand with the fundamentals of NS3, a discrete-event network simulator, and few foundational comprehending of RIP.

Following is a structural approach to start and configure a RIP protocol project using NS3.

Steps to Start RIP Protocol Projects in NS3

  1. Install NS3

Download and configure NS3, if we haven’t installed it. For installation on a Linux environment:

# Update system and install prerequisites

sudo apt update

sudo apt install -y gcc g++ python3 python3-dev cmake libgsl-dev libsqlite3-dev

# Clone NS-3 and navigate to its directory

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

cd ns-3

# Build NS-3

./ns3 configure –enable-examples –enable-tests

./ns3 build

  1. Create a New Script for RIP Simulation
  1. Go to text editor and make a new NS3 script like rip_simulation.cc.
  2. NS3 supports RIP through the Ipv4RoutingHelper and particularly with RipHelper.

Below is a basic skeleton code to configure RIP in NS3.

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/ipv4-static-routing-helper.h”

#include “ns3/rip-helper.h”

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

using namespace ns3;

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

// Set up logging if needed

LogComponentEnable(“RipExample”, LOG_LEVEL_INFO);

// Create nodes

NodeContainer nodes;

nodes.Create(4); // example with 4 nodes

// Set up point-to-point links

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“1Mbps”));

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

// Set up device containers for each link

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

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

NetDeviceContainer devicesCD = pointToPoint.Install(nodes.Get(2), nodes.Get(3));

// Install Internet stack with RIP on all nodes

RipHelper ripRouting;

InternetStackHelper internet;

internet.SetRoutingHelper(ripRouting); // Use RIP for routing

internet.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

ipv4.Assign(devicesAB);

ipv4.SetBase(“10.1.2.0”, “255.255.255.0”);

ipv4.Assign(devicesBC);

ipv4.SetBase(“10.1.3.0”, “255.255.255.0”);

ipv4.Assign(devicesCD);

// Enable routing tables

Ipv4GlobalRoutingHelper::PopulateRoutingTables();

// Run simulation

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Build and Run the Simulation
  1. In the scratch folder of NS3 directory, we need to store the file rip_simulation.cc.
  2. In the terminal, pass through NS3 directory and then we make the script:

./ns3 build

  1. Run the simulation:

./ns3 run scratch/rip_simulation

  1. Analyze the Results

We can allow to record or packet tracing to examine the behaviour of RIP and routing table exchanges among the nodes, after executing the simulation. For instance, we can utilize:

LogComponentEnable(“Ipv4L3Protocol”, LOG_LEVEL_INFO);

LogComponentEnable(“Rip”, LOG_LEVEL_INFO);

This guide will provide you simple routing functionality including RIP. We can test with diverse network topologies, modify RIP timers, or examine network performance parameters relevant to RIP.

In this setup, we had presented the simple simulation method with examples that helps you to easily understand the concepts and process on how to initiate and configure the RIP Protocol projects using NS3. More elaborated approach will also be sent on this topic as required.

We manage the configuration and replication of Routing Information Protocol scenarios. For initiating RIP Protocol projects using NS3, it is essential to engage only experts for your tasks. phdprojects.org team  consists of highly skilled and knowledgeable writers and developers, providing you with tailored services that ensure timely delivery and high quality.
