How to Implement IEEE 802.11 (Wi-Fi) in OMNeT++

To implement the IEEE 802.11 (Wi-Fi) in OMNeT++, we can use INET framework that provides wireless communication model including Wi-Fi. In below, the step-by-step implementation of IEEE 802.11 in OMNeT++:

Step-by-Step Implementation:

  1. Install OMNeT++ and INET Framework
  • Download and Install OMNeT++: Make sure to install the OMNeT++ based on your operating system.
  • Download and Install INET: Also, install the INET framework and extract the INET files into the OMNeT++ environment.
  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 and name it.(for example: WiFiSimulation).
  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: For reference, copy example configurations from the INET framework to your project.
  1. Define the Network Topology

Create a new NED file to define the network topology.

Example: Wi-Fi Network Topology (WiFiNetwork.ned)

package wifi;

import inet.node.inet.WirelessHost;

import inet.node.inet.AccessPoint;

import inet.node.inet.Router;

import inet.common.scenario.ScenarioManager;

import inet.visualizer.common.IntegratedCanvasVisualizer;

network WiFiNetwork

{

parameters:

@display(“bgb=600,400”);

submodules:

scenarioManager: ScenarioManager {

@display(“p=100,100;is=s”);

}

visualizer: IntegratedCanvasVisualizer {

@display(“p=100,200;is=s”);

}

router: Router {

@display(“p=300,200”);

}

ap: AccessPoint {

@display(“p=300,100”);

}

host1: WirelessHost {

@display(“p=100,300”);

}

host2: WirelessHost {

@display(“p=500,300”);

}

connections:

router.pppg++ <–> ap.pppg++;

}

  1. Configure the Simulation

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

Example: Configuration File (omnetpp.ini)

network = wifi.WiFiNetwork

sim-time-limit = 100s

# Visualizer

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Scenario Manager

*.scenarioManager.moduleType = “inet.common.scenario.ScenarioManager”

*.scenarioManager.managerType = “inet.scenario.ScenarioManager”

*.scenarioManager.scriptFile = xmldoc(“scenario.xml”)

# Wireless Host Configuration

*.host*.wlan[0].typename = “IdealWirelessNic”

*.host*.wlan[0].radio.typename = “Ieee80211Radio”

*.host*.wlan[0].mac.typename = “Ieee80211Mac”

*.host*.wlan[0].mac.ssid = “WiFiNetwork”

*.host*.wlan[0].mac.opMode = “b”

# Access Point Configuration

*.ap.wlan[0].typename = “IdealWirelessNic”

*.ap.wlan[0].radio.typename = “Ieee80211Radio”

*.ap.wlan[0].mac.typename = “Ieee80211Mac”

*.ap.wlan[0].mac.ssid = “WiFiNetwork”

*.ap.wlan[0].mac.opMode = “b”

*.ap.wlan[0].mac.isAP = true

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

In Conclusion, we have shown how to setup and simulate the network which is useful to implement IEEE 802.11 (Wi-Fi) in OMNeT++. We will provide any details regarding this script, if needed.

For the implementation of IEEE 802.11 (Wi-Fi) in OMNeT++, the INET framework can be utilized for your projects. Should you require assistance from leading researchers, please reach out to us for further support.
