How to Implement 6G Networks in OMNeT++

To implement the 6G networks in OMNeT++ requires a network that sets up the environment which replicate the advanced features expected in 6G like ultra-high data rates, ultra-low latency, AI-driven network management, and integration of satellite and terrestrial networks by simulating it. We have to extend the model for 6G networks, because OMNeT++ and the INET framework primarily support traditional and 5G networks. Follow this script below to know the implementation of 6G networks:

Step-by-Step Implementation:

Understand the Basics of 6G Networks

We are expecting the 6G networks to offer the extremely high data rates (up to 1 Tbps), ultra-low latency (less than 1 ms) and helps AI-driven network management and edge computing and also integrate satellite and terrestrial networks, support massive IoT deployments, and provide optimized security features.

Install OMNeT++ and INET Framework

Make sure, you have OMNeT++ and the INET Framework installed.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project and name it (for instance: 6GNetworkSimulation).

Define the Network Topology

State the network topology that contain base stations, user equipment (UE), and core network elements by generating a new NED file.

Example: 6G Network Topology (6GNetwork.ned)

package sixgnetwork;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

import inet.node.inet.WirelessHost;

network 6GNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

ue1: WirelessHost {

@display(“p=100,300”);

}

ue2: WirelessHost {

@display(“p=300,300”);

}

basestation1: WirelessHost {

@display(“p=200,200”);

}

basestation2: WirelessHost {

@display(“p=400,200”);

}

coreRouter: Router {

@display(“p=300,100”);

}

edgeServer: StandardHost {

@display(“p=500,100”);

}

connections:

ue1.wlan[0] <–> AdhocChannel <–> basestation1.wlan[0];

ue2.wlan[0] <–> AdhocChannel <–> basestation2.wlan[0];

basestation1.ethg++ <–> Eth10M <–> coreRouter.ethg++;

basestation2.ethg++ <–> Eth10M <–> coreRouter.ethg++;

coreRouter.ethg++ <–> Eth10M <–> edgeServer.ethg++;

}

Configure the Simulation

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

Example: Configuration File (omnetpp.ini)

[General]

network = sixgnetwork.6GNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# User Equipment Configuration

*.ue*.numApps = 1

*.ue*.app[0].typename = “UdpBasicApp”

*.ue*.app[0].destAddresses = “basestation1 basestation2”

*.ue*.app[0].destPort = 5000

*.ue*.app[0].messageLength = 1024B

*.ue*.app[0].sendInterval = 1s# Base Station Configuration

*.basestation*.numApps = 1

*.basestation*.app[0].typename = “UdpSink”

*.basestation*.app[0].localPort = 5000

# Core Network Configuration

*.coreRouter.numApps = 1

*.coreRouter.app[0].typename = “UdpSink”

*.coreRouter.app[0].localPort = 6000

# Edge Server Configuration

*.edgeServer.numApps = 1

*.edgeServer.app[0].typename = “UdpSink”

*.edgeServer.app[0].localPort = 7000

# UDP Configuration

*.ue*.hasUdp = true

*.basestation*.hasUdp = true

*.coreRouter.hasUdp = true

*.edgeServer.hasUdp = true

# Wireless Configuration

*.ue*.wlan[0].typename = “AdhocHost”

*.basestation*.wlan[0].typename = “AdhocHost”

# IP Address Configuration

*.ue1.ipv4.config = xmldoc(“ue1.xml”)

*.ue2.ipv4.config = xmldoc(“ue2.xml”)

*.basestation1.ipv4.config = xmldoc(“basestation1.xml”)

*.basestation2.ipv4.config = xmldoc(“basestation2.xml”)

*.coreRouter.ipv4.config = xmldoc(“coreRouter.xml”)

*.edgeServer.ipv4.config = xmldoc(“edgeServer.xml”)

Create IP Address Configuration Files

Create XML files to describe the IP address configuration for all node.

Example: IP Configuration File for ue1 (ue1.xml)

</interface>

</config>

Example: IP Configuration File for basestation1 (basestation1.xml)

</interface>

</interface>

</config>

Example: IP Configuration File for coreRouter (coreRouter.xml)

</interface>

</config>

Implement 6G Specific Features

We need to expand the INET framework to simulate 6G-specific features like:

AI-driven Network Management: Implement AI algorithms to dynamically manage network resources.
Ultra-low Latency Communication: To minimize the communication delays, we have to execute protocols.
Integration with Satellite Networks: Simulate satellite links and their integration with terrestrial networks.
Enhanced Security Features: Execute advanced security mechanisms.

Example: AI-driven Network Management Logic (Pseudo-Code)

class AIManager : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void optimizeNetwork();

};

void AIManager::initialize() {

// Initialization code

scheduleAt(simTime() + 1, new cMessage(“optimizeNetwork”));

}

void AIManager::handleMessage(cMessage *msg) {

if (strcmp(msg->getName(), “optimizeNetwork”) == 0) {

optimizeNetwork();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void AIManager::optimizeNetwork() {

// Logic to optimize network resources using AI algorithms

}

Run the Simulation

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