How to Begin Implementing a 5G Beyond Networks in NS3

To begin executing a 5G Beyond (B5G) networks project in NS3, we can follow systematic approach that helps to replicate more advanced aspects such as ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), and enhanced mobile broadband (eMBB). Here’s a step-by-step guide to get started:

Steps to Begin Implementing a 5G Beyond Networks Projects in NS3

1. Understand the Scope of 5G Beyond

• Detect the B5G networks’ certain feature for simulating:
  • eMBB: Study high data rates and bandwidth.
  • URLLC: Highlight low latency and high reliability.
  • mMTC: Replicate massive IoT connectivity.
  • Advanced Features: Aspects like beamforming, network slicing, or AI-based resource allocation.

2. Get Familiar with NS3 and 5G Modules

• Install NS3:
  • Make sure that we have installed the new version of NS3.
  • For reference, we should utilise NS3 installation instructions.
• Install 5G Modules:
  • While NS3 doesn’t have direct support for 5G, extensions such as 5G-LENA or custom libraries are obtainable.
  • We can set up 5G-LENA for 5G simulation abilities.
• Learn Basics of NS3:
  • Focus on the fundamental aspects, components, and how to make nodes, links, and applications.

3. Define the Simulation Objectives

• Describe the project’s objectives like:
  • To examine the network slicing performance.
  • Experiment AI-based resource allocation.
  • Measuring the metrics like latency and reliability for URLLC.

4. Design the Network Architecture

• Components of a 5G Beyond Network:
  • gNB (Base Stations): Replicate more advanced base station functionalities.
  • UEs (User Equipment): Set up user devices including diverse traffic needs.
  • Core Network: Execute the abilities of network slicing or edge computing.
• Topology: Select the arrangement in cellular, mesh topology.

5. Configure Simulation Parameters

Step A: Radio Access Network (RAN)

1. Configure gNB and UE:
   • For RAN configuration, we can apply LteHelper or NrHelper.
   • Configure metrics such as frequency, bandwidth, and duplexing mode (FDD/TDD).
2. Enable Advanced Features:
   • Execute the MIMO, beamforming, or carrier aggregation to allow further aspects.

Step B: Core Network

• Replicate the end-to-end connectivity to exploit Internet or EPC modules.
• Integrate aspects such as network slicing or edge computing.

Step C: Traffic Models

• Mimic diverse traffic models:
  • mMTC: IoT device connections.
  • eMBB: High throughput video streaming.
  • URLLC: Low latency industrial control.

6. Write the Simulation Code

Example: Basic 5G Network Simulation in NS3

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-helper.h”

#include “ns3/5g-helper.h”

using namespace ns3;

int main() {

// Create Nodes

NodeContainer gNbNodes, ueNodes;

gNbNodes.Create(1); // One gNB

ueNodes.Create(10); // Ten UEs

// Install Internet Stack

InternetStackHelper internet;

internet.Install(ueNodes);

// Create 5G Helper

Ptr<NrHelper> nrHelper = CreateObject<NrHelper>();

// Configure gNB and UE devices

NetDeviceContainer gNbDevices = nrHelper->InstallGnb(gNbNodes);

NetDeviceContainer ueDevices = nrHelper->InstallUe(ueNodes);

// Assign IP Addresses

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer ueInterfaces = ipv4.Assign(ueDevices);

// Attach UEs to gNB

nrHelper->AttachToClosestEnb(ueDevices, gNbDevices);

// Install Applications (e.g., Video Streaming)

uint16_t port = 8080;

UdpServerHelper server(port);

ApplicationContainer serverApps = server.Install(gNbNodes.Get(0));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

UdpClientHelper client(ueInterfaces.GetAddress(0), port);

client.SetAttribute(“MaxPackets”, UintegerValue(1000));

client.SetAttribute(“Interval”, TimeValue(Seconds(0.01)));

client.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = client.Install(ueNodes.Get(0));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Run Simulation

Simulator::Run();

Simulator::Destroy();

return 0;

}

7. Implement Advanced Features

• MIMO and Beamforming:
  • Mimic spatial multiplexing and antenna set up.
• Network Slicing:
  • Make distinct network slices for eMBB, URLLC, and mMTC to utilize virtualized networks.
• Edge Computing:
  • Add MEC (Mobile Edge Computing) servers for edge computing.
• AI/ML Algorithms:
  • It contains custom scheduling or resource allocation mechanisms.

8. Simulate and Analyze Results

• Metrics to Evaluate:
  • Measure the performance parameters such as throughput, latency, packet delivery ratio, and energy efficiency.
• Visualization Tools:
  • For basic visualizations, we need to utilize NetAnim tool.
  • Transfer records within MATLAB or Python tools for analysis.

9. Validate and Compare

• Equate the performance outcomes with existing research or theoretical models.
• Restate and improve the performance according to the outcomes.

10. Document Your Work

• The project should have comprehensive descriptions of configurations, code, and outcomes.
• It offers graphs, tables, and a conversation on insights.
