How to Implement IEEE 802.3 (Ethernet) in OMNeT++

To implement the IEEE 802.3 (Ethernet) in OMNeT++ needs a network which is simulated to use Ethernet protocols to model the wired communication amongst devices. OMNeT++’s INET framework offers the in-built support for Ethernet. Here’s a step-by-step guide to setting up an Ethernet network simulation in OMNeT++:

Step-by-Step Implementation:

  1. Install OMNeT++ and INET Framework
  • Download and Install OMNeT++: Make sure to install the OMNeT++.
  • Download and Install INET: Install the INET framework on your OMNeT++ environment and extract the INET files in it.
  1. Create a New OMNeT++ Project
  1. Open OMNeT++ IDE: Start the OMNeT++ IDE.
  2. Create a New Project: Go to File -> New -> OMNeT++ Project. Name your project (for example: EthernetSimulation).
  1. Import INET into Your Project
  1. Import INET: In Project Explorer, right-click on project, select Properties. Go to Project References and check the INET project.
  2. Copy INET Examples: Copy example configurations from the INET framework to the project for reference.
  1. Define the Network Topology

Create a new NED file to state the network topology.

Example: Ethernet Network Topology (EthernetNetwork.ned)

package ethernet;

import inet.node.inet.StandardHost;

import inet.node.ethernet.EthernetSwitch;

import inet.node.ethernet.EthernetHost;

network EthernetNetwork

{

parameters:

@display(“bgb=600,400”);

submodules:

host1: EthernetHost {

@display(“p=100,200”);

}

host2: EthernetHost {

@display(“p=300,200”);

}

host3: EthernetHost {

@display(“p=500,200”);

}

switch: EthernetSwitch {

@display(“p=300,100”);

}

connections:

host1.ethg++ <–> Eth10M <–> switch.ethg++;

host2.ethg++ <–> Eth10M <–> switch.ethg++;

host3.ethg++ <–> Eth10M <–> switch.ethg++;

}

In this instance:

  • host1, host2, and host3 are Ethernet hosts.
  • switch is an Ethernet switch.
  • The Eth10M channel models a 10 Mbps Ethernet link.
  1. Configure the Simulation

Create an OMNeT++ initialization file to configure the parameters of the simulation.

Example: Configuration File (omnetpp.ini)

network = ethernet.EthernetNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.host*.numEthInterfaces = 1

# Ethernet Switch Configuration

*.switch.numPorts = 3

  1. Run the Simulation
  1. Build the Project: Right-click on the project and select Build Project.
  2. Run the Simulation: In the OMNeT++ IDE, click on the green play button to start the simulation.

Analyzing Results

  • Use OMNeT++ Tools: OMNeT++ provides built-in tools for analyzing the simulation results like Qtenv runtime environment and different visualization tools.
  • Export Data: We can export the simulation data for further analysis using external tools like Python or MATLAB.
