How to Start 5G Network Projects Using OMNeT++

To start 5G Network projects in OMNeT++ that has sequential steps to replicate the 5G Networks’ advanced aspects like ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), network slicing and massive machine-type communication (mMTC). OMNeT++ environment integrated with some frameworks such as SimuLTE and INET those offers a robust platform, designing and examining the 5G network scenarios. Here’s a detailed approach to get started:

Steps to Start 55G Networks Projects in OMNeT++

  1. Install OMNeT++
  • Download: Go to official OMNeT webpage to get the new version of it.
  • Install and Verify: Stick to the installation guide according to the operating system. Make sure that OMNeT++ IDE is properly installed.
  1. Install Required Frameworks

To mimic 5G networks we will be required frameworks, which have wireless communication, mobility, and LTE/5G protocols.

Frameworks:

  1. INET Framework:
    • From official INET page, we can download it.
    • This framework offers wireless interaction models, protocols, and mobility.
  2. SimuLTE Framework:
    • It prolongs INET for LTE/5G simulation to have eNodeB, gNodeB, UEs, and core network components.
    • Go to SimuLTE’s GitHub repository, we download this framework.
  3. 5G Extensions for SimuLTE:
    • It contains aspects such as network slicing, URLLC, mMTC, and eMBB.

Installation Steps:

  1. We want to download the essential framework(s).
  2. Get the file from the OMNeT++ workspace.
  3. We should import the framework in OMNeT++ as File > Import > Existing Projects.
  4. In the IDE, form the framework.
  1. Understand 5G Network Features

To replicate the 5G networks’ crucial components include:

  • Network Slicing: For various use cases, virtualized network slices.
  • URLLC: It has low-latency and high-reliability interaction.
  • mMTC: It assist for massive IoT device connectivity.
  • eMBB: For improved broadband services, supports high data rates.
  • Beamforming: It used in directional signal transmission for efficiency.
  • Mobility and Handover: Seamless connectivity in the course of node movement.
  1. Define Network Topology

Delineate the 5G network design with gNodeBs (base stations), UEs (user equipment), and core network elements with the help of .ned files.

Example .ned File for 5G Network:

network FiveGNetwork

{

submodules:

gNodeB[0..2]: GNodeB;       // Array of 3 base stations

ue[0..9]: UE;               // Array of 10 user devices

coreNetwork: CoreNetwork;   // Core network element

connections allowunconnected:

ue[*].lteNic <–> gNodeB[*].lteNic; // UEs connect to nearest base station

gNodeB[*].core <–> coreNetwork.core;

}

  1. Implement 5G Communication Logic
  • Applications:
    • 5G networks supported in built-in applications such as VideoStreamingApp, TcpApp, or UdpBasicApp.
  • Routing and Handover:
    • We execute the routing protocols and mobility-aware handovers.
  • Quality of Service (QoS):
    • Design the service difference for slices like eMBB, URLLC, mMTC.

Example C++ Code for gNodeB Handover Logic:

void GNodeB::handleHandoverRequest(UE *ue)

{

if (ue->getSignalStrength() < handoverThreshold)

{

findNearestGNodeB(ue);

initiateHandover(ue);

}

}

  1. Configure Simulation Parameters

In the omnetpp.ini file, we need to configure the 5G-specific simulation metrics.

Example Configuration:

[General]

network = FiveGNetwork

sim-time-limit = 500s

*.gNodeB[*].transmissionPower = 30dBm

*.gNodeB[*].bandwidth = 100MHz

*.ue[*].mobility.speed = uniform(1, 10)

*.ue[*].applicationType = “VideoStreamingApp”

# QoS Parameters for Slices

*.gNodeB[*].slices[0].type = “eMBB”

*.gNodeB[*].slices[1].type = “URLLC”

*.gNodeB[*].slices[2].type = “mMTC”

  1. Simulate Mobility

In 5G networks, mobility is fundamental. Mimic user movement to utilize the framework INET or SimuLTE’s mobility models.

Example Mobility Configuration:

*.ue[*].mobilityType = “MassMobility”

*.ue[*].mobility.speed = uniform(1, 20)  # Random speed between 1 and 20 m/s

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

  1. Run the Simulation
  • Run the Simulation:
    • We need to execute the simulation by right-clicking on the omnetpp.ini file and then choosing Run As > OMNeT++ Simulation.
  • Debugging:
    • Observe the behaviour of network making use of logging and visualization tools.
  • Visualization:
    • Monitor mobility, data flow, and handovers within the GUI simulation.
  1. Analyze Results
  • Metrics to Evaluate: We can measure the performance parameters such as:
    • Throughput and latency for various slices.
    • Packet delivery ratio.
    • Handover success rate and delay.
    • Resource utilization and QoS satisfaction.
  • Tools for Analysis:
    • Make utilize of OMNeT++’s built-in analysis tools for .sca and .vec files.
    • Transfer information into Python, MATLAB, or Excel for visualization.
  1. Extend the Project
  • Network Slicing:
    • We replicate several slices including various QoS needs in network slicing.
  • Beamforming:
    • Design directional antenna transmission for better effectiveness.
  • Energy Efficiency:
    • Mimic power-saving methods for IoT devices.
  • Security:
    • We execute an encryption, authentication, or attack detection for network security.
  • Integration with IoT:
    • Replicate mMTC scenarios including numerous IoT devices.

Example Use Cases for 5G Projects

  1. URLLC Simulation:
    • For autonomous vehicles or industrial automation, experiment the ultra-reliable low-latency interaction.
  2. Smart City IoT:
    • Utilize mMTC to design massive IoT device connectivity.
  3. eMBB Applications:
    • We need to replicate the high-bandwidth applications such as video streaming or AR/VR.
  4. Network Slicing:
    • In multi-slice networks, we able to estimate the resource allocation and QoS.
  5. Handover Performance:
    • Then, examine the handover performance of seamless connectivity for high-speed mobility scenarios.
