How to Simulate EIGRP Protocol Projects Using NS3

To simulate the Enhanced Interior Gateway Routing Protocol (EIGRP) using NS3, we will required to follow a general approach because of NS3 and it doesn’t natively support EIGRP, contrasting some other routing protocols such as OSPF or RIP. Send us all your research details we will guide you with best simulation results. However, we can still implement or simulate it by customizing NS3. Here’s how to proceed:

Steps to Simulate EIGRP in NS3:

1. Install NS3: Initiate, make sure that we have NS3 installed on the computer.
2. Familiarize with NS3 and Routing: Before executing EIGRP, it’s useful to be familiar with routing protocols already available in NS3, like OSPF, BGP, or static routing. Evaluation NS3’s documentation on these protocols to familarise how routing is executed.
3. Understand EIGRP Protocol: While EIGRP is a distance vector routing protocol with advanced characteristics such as Diffusing Update Algorithm (DUAL), reliable transport, and fast convergence, ensure to understand its key mechanisms:
   • Route discovery and management.
   • Successor and feasible successor routes.
   • Metric calculation based on bandwidth and delay.
4. Modify or Extend an Existing Routing Protocol:
   • We can utilize the Distance Vector (DV) or Link State routing protocols available in NS3 as a base.
   • Initiate with the code for a similar routing protocol like RIP and adjust it to integrate EIGRP-like behavior, like EIGRP’s metric calculation and its dual algorithm.
5. Create EIGRP Classes:
   • We will require defining new C++ classes for the EIGRP protocol that could prolong NS3’s RoutingProtocol base class.
   • Apply EIGRP packet structure for hello messages, update messages, query, and reply messages.
   • Execute the EIGRP DUAL technique for selecting the best routes.
6. Handle EIGRP Packets:
   • Generate functions to create and parse EIGRP packets. NS3 has a Packet class that can be utilized to construct and deconstruct packets.
   • Utilize NS3’s UdpSocket for reliable transport of EIGRP packets among nodes.
7. Topology Creation:
   • Once EIGRP functionality is executed, generate a network topology in NS3 by describing nodes and links using NS3’s helper classes.
   • Configure the network with numerous nodes to replicate different routing behaviours and validate how EIGRP performs on the network.
8. Testing and Visualization:
   • Validate the implementation by executing the simulations and measuring routing tables and packet transmissions.
   • Utilize NS3 tools such as NetAnim to envision the routing behavior and packet flows.
9. Performance Analysis:
   • Evaluate the performance of EIGRP simulation by relating it with other protocols like OSPF or RIP.
   • Measure the convergence time, packet delivery ratio, delay, and throughput for numerous scenarios.

Example Skeleton Code:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/applications-module.h”

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

#include “ns3/eigrp-routing-protocol.h”  // Custom EIGRP implementation header

using namespace ns3;

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

{

// Step 1: Set up a basic network

NodeContainer nodes;

nodes.Create (4);

PointToPointHelper pointToPoint;

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

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

NetDeviceContainer devices;

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

// Step 2: Install Internet stack and EIGRP

InternetStackHelper internet;

EigrpHelper eigrp;

internet.SetRoutingHelper (eigrp);

internet.Install (nodes);

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces;

interfaces = address.Assign (devices);

// Step 3: Applications and Traffic

UdpEchoServerHelper echoServer (9);

ApplicationContainer serverApps = echoServer.Install (nodes.Get (1));

serverApps.Start (Seconds (1.0));

serverApps.Stop (Seconds (10.0));

UdpEchoClientHelper echoClient (interfaces.GetAddress (1), 9);

echoClient.SetAttribute (“MaxPackets”, UintegerValue (1));

echoClient.SetAttribute (“Interval”, TimeValue (Seconds (1.0)));

echoClient.SetAttribute (“PacketSize”, UintegerValue (1024));

ApplicationContainer clientApps = echoClient.Install (nodes.Get (0));

clientApps.Start (Seconds (2.0));

clientApps.Stop (Seconds (10.0));

// Step 4: Run the simulation

Simulator::Run ();

Simulator::Destroy ();

return 0;
