How to Implement 5G Network in OMNeT++
To implement the 5G network in OMNeT++ that needs environment which includes 5G nodes, defining network models, implementing 5G-specific communication protocols, and running simulations by building it. Here, we provide the implementation of 5G network in OMNeT++:
Step-by-Step Implementation:
Step 1: Install OMNeT++, INET Framework, and Simu5G
- Download OMNeT++:
- Get the latest version of the OMNeT++.
- Install OMNeT++:
- Follow the installation details about what fits the operating system.
- Download and Install INET Framework:
- The INET framework provides models for internet protocols and is often used with OMNeT++.
- Install the INET framework on your system
- Download and Install Simu5G:
- Simu5G is a 5G network simulator built on top of OMNeT++ and INET.
- Install the Simu5G from the Simu5G GitHub repository.
Step 2: Set Up Your Project
- Create a New OMNeT++ Project:
- Open the OMNeT++ IDE.
- Go to File -> New -> OMNeT++ Project.
- Enter a project name and select the proper options.
- Set Up Directory Structure:
- Make sure that the project contains essential like src for source files and simulations for NED files and configuration.
- Add INET and Simu5G to Your Project:
- Right-click on project in the Project Explorer.
- Select Properties -> Project References.
- Check the boxes for INET and Simu5G.
Step 3: Define 5G Network Models Using NED
- Create NED Files:
- Create a new NED file (e.g., 5GNetwork.ned) in the src directory.
- Define the network topology in the NED file. Here’s a sample we offer:
package fiveg;
import inet.node.inet.StandardHost;
import inet.node.inet.Router;
import inet.networklayer.configurator.ipv4.Ipv4NetworkConfigurator;
import inet.physicallayer.common.packetlevel.RadioMedium;
import inet.mobility.single.RandomWaypointMobility;
import simu5g.node.ue.UE;
import simu5g.node.enb.ENB;
import simu5g.node.gnb.GNB;
import simu5g.node.core5g.AMF;
network 5GNetwork
{
parameters:
int numUEs = default(10);
types:
channel radioChannel extends RadioMedium {}
submodules:
configurator: Ipv4NetworkConfigurator {
@display(“p=100,100”);
}
gnb: GNB {
@display(“p=300,200”);
}
amf: AMF {
@display(“p=500,200”);
}
ue[numUEs]: UE {
@display(“p=200+100*i,400”);
mobility.typename = “RandomWaypointMobility”;
}
radioMedium: radioChannel {
@display(“p=400,100”);
}
connections allowunconnected:
for i=0..numUEs-1 {
ue[i].wlan[0] <–> radioMedium <–> gnb.wlan[0];
}
gnb.ethg++ <–> Ethernet100M <–> amf.ethg++;
}
Step 4: Implement 5G Communication Logic in C++
- Create C++ Modules:
- In the src directory, create a new C++ class (e.g., 5GApp.cc).
- It should contain essential OMNeT++ headers and define your module:
#include <omnetpp.h>
#include “inet/applications/base/ApplicationBase.h”
#include “inet/applications/udpapp/UdpBasicApp.h”
#include “inet/networklayer/common/L3AddressResolver.h”
#include “inet/networklayer/contract/ipv4/Ipv4Address.h”
#include “inet/networklayer/contract/IL3AddressType.h”
using namespace omnetpp;
using namespace inet;
class FiveGApp : public ApplicationBase
{
protected:
virtual void initialize(int stage) override;
virtual void handleMessageWhenUp(cMessage *msg) override;
void sendPacket();
void handlePacket(cPacket *pkt);
};
Define_Module(FiveGApp);
void FiveGApp::initialize(int stage)
{
ApplicationBase::initialize(stage);
if (stage == INITSTAGE_LOCAL) {
// Initialization code
if (par(“sendPackets”).boolValue()) {
scheduleAt(simTime() + par(“startDelay”), new cMessage(“sendPacket”));
}
}
}
void FiveGApp::handleMessageWhenUp(cMessage *msg)
{
if (msg->isSelfMessage()) {
if (strcmp(msg->getName(), “sendPacket”) == 0) {
sendPacket();
scheduleAt(simTime() + par(“sendInterval”), msg);
}
} else {
cPacket *pkt = check_and_cast<cPacket *>(msg);
handlePacket(pkt);
}
}
void FiveGApp::sendPacket()
{
// Create and send a packet
EV << “Sending packet” << endl;
cPacket *pkt = new cPacket(“FiveGPacket”);
pkt->setByteLength(par(“packetSize”));
send(pkt, “lowerLayerOut”);
}
void FiveGApp::handlePacket(cPacket *pkt)
{
// Handle received packet
EV << “Received packet: ” << pkt->getName() << endl;
delete pkt;
}
- Modify NED to Use C++ Modules:
- Update your NED file to use custom application module:
network 5GNetwork
{
parameters:
int numUEs = default(10);
types:
channel radioChannel extends RadioMedium {}
submodules:
configurator: Ipv4NetworkConfigurator {
@display(“p=100,100”);
}
gnb: GNB {
@display(“p=300,200”);
}
amf: AMF {
@display(“p=500,200”);
}
ue[numUEs]: UE {
@display(“p=200+100*i,400”);
mobility.typename = “RandomWaypointMobility”;
@children:
udpApp: FiveGApp {
localPort = 12345;
destPort = 54321;
startTime = uniform(0, 1s);
packetSize = 512B;
sendInterval = exponential(1s);
}
}
radioMedium: radioChannel {
@display(“p=400,100”);
}
connections allowunconnected:
for i=0..numUEs-1 {
ue[i].wlan[0] <–> radioMedium <–> gnb.wlan[0];
}
gnb.ethg++ <–> Ethernet100M <–> amf.ethg++;
}
Step 5: Configure Simulation Parameters
- Create omnetpp.ini:
- Create an omnetpp.ini file in the simulation directory.
- State simulation parameters like the duration and network parameters:
[General]
network = 5GNetwork
sim-time-limit = 100s
**.sendPackets = true
**.startDelay = 1s
**.sendInterval = 2s
**.packetSize = 512B
**.ue[*].mobility.typename = “inet.mobility.single.RandomWaypointMobility”
Step 6: Build and Run the Simulation
- Build the Project:
- In the OMNeT++ IDE, right-click on project and select Build Project.
- Run the Simulation:
- Go to Run -> Run Configurations.
- Build a new run configuration for project and run the simulation.
Step 7: Analyze Results
- View Simulation Results:
- With the help of OMNeT++’s tools to analyze the results only after the simulation completed.
- Open the ANF (Analysis Framework) to visualize and interpret the data
