How to Implement 5G Beyond networks in OMNeT++

To implement the 5G beyond networks in OMNeT++, we have to create an environment that has advanced features and technologies past standard 5G like ultra-dense networks, massive MIMO, millimeter-wave communication, and advanced beamforming methods. Enquire us for best simulation results from top developers for your projects.

Here, we provide the details on how to set up the 5G beyond networks in OMNeT++:

Step-by-Step Implementation:

Step 1: Install OMNeT++ and INET Framework

1. Download OMNeT++:
   • Download the latest version of OMNeT++ .
2. Install OMNeT++:
   • Make sure to follow the installation instructions.
3. Download and Install INET Framework:
   • The INET framework provides models for internet protocols and is often used with OMNeT++.
   • Install the INET framework in your computer.

Step 2: Set Up Your Project

1. Create a New OMNeT++ Project:
   • Open the OMNeT++ IDE.
   • Go to File -> New -> OMNeT++ Project.
   • Enter a project name and select the appropriate options.
2. Set Up Directory Structure:
   • Verify the project has essential folders like src for source files and simulations for NED files and configuration.
3. Add INET to Your Project:
   • Right-click on project in the Project Explorer.
   • Select Properties -> Project References.
   • Check the box for INET.

Step 3: Define 5G Beyond Network Models Using NED

1. Create NED Files:
   • We have to create a new NED file (e.g., 5GBeyondNetwork.ned) in the src directory.
   • State the network topology in the NED file. Here’s an example:

package fivegbeyond;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

import inet.node.wireless.AccessPoint;

import inet.mobility.single.RandomWaypointMobility;

import inet.physicallayer.common.packetlevel.RadioMedium;

network 5GBeyondNetwork

{

parameters:

int numUEs = default(10);

int numGNBs = default(3);

int numBackhaulRouters = default(2);

types:

channel radioChannel extends RadioMedium {}

submodules:

radioMedium: radioChannel {

@display(“p=100,100”);

}

gNB[numGNBs]: Router {

@display(“p=200+200*i,200”);

}

ue[numUEs]: StandardHost {

@display(“p=300+50*i,300”);

mobility.typename = “RandomWaypointMobility”;

}

backhaulRouter[numBackhaulRouters]: Router {

@display(“p=400+200*i,100”);

}

connections allowunconnected:

for i=0..numGNBs-1 {

gNB[i].ethg++ <–> radioMedium <–> backhaulRouter[i % numBackhaulRouters].ethg++;

}

for i=0..numUEs-1 {

ue[i].wlan[0] <–> radioMedium <–> gNB[i % numGNBs].wlan[0];

}

}

Step 4: Implement 5G Beyond Communication Logic

1. Create C++ Modules for Advanced 5G Features:
   • create new C++ classes (like MassiveMIMO.cc, Beamforming.cc, MillimeterWave.cc) in the src directory.
   • Comprise necessary OMNeT++ headers and define advanced 5G communication logic.
2. Example: Massive MIMO Implementation:

#include <omnetpp.h>

#include “inet/applications/base/ApplicationBase.h”

#include “inet/common/packet/Packet.h”

using namespace omnetpp;

using namespace inet;

class MassiveMIMO : public ApplicationBase

{

protected:

virtual void initialize(int stage) override;

virtual void handleMessageWhenUp(cMessage *msg) override;

void performMassiveMIMO();

void handleMassiveMIMOPacket(Packet *pkt);

cMessage *mimoEvent = nullptr;

};

Define_Module(MassiveMIMO);

void MassiveMIMO::initialize(int stage)

{

ApplicationBase::initialize(stage);

if (stage == INITSTAGE_LOCAL) {

mimoEvent = new cMessage(“performMassiveMIMO”);

scheduleAt(simTime() + par(“mimoStartTime”), mimoEvent);

}

}

void MassiveMIMO::handleMessageWhenUp(cMessage *msg)

{

if (msg == mimoEvent) {

performMassiveMIMO();

scheduleAt(simTime() + par(“mimoInterval”), mimoEvent);

} else {

Packet *pkt = check_and_cast<Packet *>(msg);

handleMassiveMIMOPacket(pkt);

}

}

void MassiveMIMO::performMassiveMIMO()

{

// Implement Massive MIMO processing logic

EV << “Performing Massive MIMO” << endl;

}

void MassiveMIMO::handleMassiveMIMOPacket(Packet *pkt)

{

// Handle received Massive MIMO packet

EV << “Received Massive MIMO packet: ” << pkt->getName() << endl;

delete pkt;

}

Step 5: Integrate 5G Beyond Modules into Network Model

1. Modify NED File to Use Advanced 5G Modules:
   • Apprise your NED file with the help of custom modules for advanced 5G features:

package fivegbeyond;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

import inet.physicallayer.contract.packetlevel.IRadioMedium;

import inet.physicallayer.common.packetlevel.RadioMedium;

network 5GBeyondNetwork

{

parameters:

int numUEs = default(10);

int numGNBs = default(3);

int numBackhaulRouters = default(2);

submodules:

radioMedium: RadioMedium {

@display(“p=100,100”);

}

gNB[numGNBs]: Router {

@display(“p=200+200*i,200”);

@children:

wlan[0].radio.transmitter.typename = “MassiveMIMO”;

wlan[0].radio.receiver.typename = “MassiveMIMO”;

}

ue[numUEs]: StandardHost {

@display(“p=300+50*i,300”);

mobility.typename = “RandomWaypointMobility”;

}

backhaulRouter[numBackhaulRouters]: Router {

@display(“p=400+200*i,100”);

}

connections allowunconnected:

for i=0..numGNBs-1 {

gNB[i].ethg++ <–> radioMedium <–> backhaulRouter[i % numBackhaulRouters].ethg++;

}

for i=0..numUEs-1 {

ue[i].wlan[0] <–> radioMedium <–> gNB[i % numGNBs].wlan[0];

}

}

Step 6: Configure Simulation Parameters

1. Create omnetpp.ini:
   • Create an omnetpp.ini file in the simulation directory.
   • Define simulation parameters like duration and network parameters:

[General]

network = 5GBeyondNetwork

sim-time-limit = 100s

# Mobility

**.ue[*].mobility.bounds = “0,0,1000,1000”

# Massive MIMO application parameters

**.gNB[*].udpApp.startTime = uniform(0s, 10s)

**.gNB[*].udpApp.sendInterval = exponential(1s)

**.gNB[*].udpApp.messageSize = 256B

**.gNB[*].udpApp.localPort = 1000

**.gNB[*].udpApp.destPort = 2000

# UE application parameters

**.ue[*].udpApp.startTime = uniform(0s, 10s)

**.ue[*].udpApp.sendInterval = exponential(1s)

**.ue[*].udpApp.messageSize = 256B

**.ue[*].udpApp.localPort = 3000

**.ue[*].udpApp.destPort = 4000

Step 7: Build and Run the Simulation

1. Build the Project:
   • In the OMNeT++ IDE, right-click on project and select Build Project.
2. Run the Simulation:
   • Go to Run -> Run Configurations.
   • Build new run configuration for your project and run the simulation.

Step 8: Analyze Results

1. View Simulation Results:
   • Once the simulation is done, use OMNeT++’s tools to analyze the results.
   • Open the ANF (Analysis Framework) to visualize and interpret the data.

Finally, this guide will help you set up a basic simulation in OMNeT++ using the INET framework and expand it using custom modules. For further queries, you can reach out to us about 5G beyond networks or related to this topic.
