Send us all your queries we will provide you tailored services. The following is an extensive instruction based on how to carry out this simulation process with mmWave module and ns-3, which assist you in an efficient manner: 

Step 1: Install ns-3 and the mmWave Module

  1. Download and Install ns-3: First, you must make sure that you have installed ns-3 on your system. Directly from the authorized ns-3 website, you can download ns-3.
  2. Clone the mmWave Module: It is approachable to copy the mmWave module repository, especially when you are considering mmWave interaction for 5G.

git clone https://github.com/signetlabdei/mmwave.git 

  1. Construct ns-3 with the mmWave Module: After that, direct to the ns-3 file. By using mmWave module, construct ns-3.

cd ns-3-allinone

./download.py

cd ns-3-dev

./waf configure –enable-examples –enable-tests

./waf build

Step 2: Develop a Simulation Script

To configure your 5G network simulation, alter the previous simulation script or develop a novel one. 

Instance of Simulation Script

Consider the following simple instance that depicts the 5G network simulation script with the mmWave module, specifically in C++ language:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

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

#include “ns3/mobility-module.h”

#include “ns3/mmwave-helper.h”

#include “ns3/mmwave-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

int main(int argc, char *argv[])

{

    double simTime = 10.0;

    uint16_t numUeNodes = 2;

    uint16_t numEnbNodes = 1;

    // Create nodes

    NodeContainer ueNodes;    ueNodes.Create(numUeNodes);    NodeContainer enbNodes;    enbNodes.Create(numEnbNodes);

    // Set up the mobility model

    MobilityHelper mobility;    mobility.SetMobilityModel(“ns3::ConstantPositionMobilityModel”);

    mobility.Install(ueNodes);

    mobility.Install(enbNodes);

    // Set up the mmWave helper

    Ptr<MmWaveHelper> mmwaveHelper = CreateObject<MmWaveHelper>();

    mmwaveHelper->SetSchedulerType(“ns3::MmWaveFlexTtiMaxWeightMacScheduler”);

    // Install mmWave devices on the nodes

    NetDeviceContainer enbDevices = mmwaveHelper->InstallEnbDevice(enbNodes);

    NetDeviceContainer ueDevices = mmwaveHelper->InstallUeDevice(ueNodes);

    // Attach the UEs to the eNB

    mmwaveHelper->AttachToClosestEnb(ueDevices, enbDevices);

    // Set up the Internet stack

    InternetStackHelper internet;

    internet.Install(ueNodes);

    internet.Install(enbNodes);

    // Assign IP addresses

    Ipv4AddressHelper ipv4;

    ipv4.SetBase(“7.0.0.0”, “255.0.0.0”);

    Ipv4InterfaceContainer enbIpIfaces = ipv4.Assign(enbDevices);

    Ipv4InterfaceContainer ueIpIfaces = ipv4.Assign(ueDevices);

    // Set up applications

    uint16_t dlPort = 1234;

    OnOffHelper onOffHelper(“ns3::UdpSocketFactory”, InetSocketAddress(ueIpIfaces.GetAddress(0), dlPort));    onOffHelper.SetConstantRate(DataRate(“100Mbps”));

    ApplicationContainer clientApps = onOffHelper.Install(enbNodes.Get(0));    clientApps.Start(Seconds(1.0));    clientApps.Stop(Seconds(simTime));

    PacketSinkHelper packetSinkHelper(“ns3::UdpSocketFactory”, InetSocketAddress(Ipv4Address::GetAny(), dlPort));

    ApplicationContainer serverApps = packetSinkHelper.Install(ueNodes.Get(0));    serverApps.Start(Seconds(1.0));

    serverApps.Stop(Seconds(simTime));

    // Enable tracing

    mmwaveHelper->EnableTraces();

    // Run the simulation    Simulator::Stop(Seconds(simTime));

    Simulator::Run();

    Simulator::Destroy();

    return 0;

}

Step 3: Construct and Execute the Simulation

  1. Save the Script: In the scratch file of your ns-3 installation, the above specified script has to be saved as mmwave-simulation.cc.
  2. Construct the Simulation: For the compilation of your script, utilize the waf build system.

./waf build

  1. Execute the Simulation: Employ the below specified command to run the script.

./waf –run scratch/mmwave-simulation

Step 4: Analyze the Results

  1. Facilitate Tracing: To gather in-depth simulation data, you need to make sure that the tracing is facilitated in your script.

mmwaveHelper->EnableTraces();

  1. Gather Performance Metrics: Several performance metrics like energy utilization, packet loss, latency, and throughput are offered by NetSim. By means of the built-in analysis tools, evaluate these potential metrics.
  2. Examine Outcomes: For examining the 5G network’s performance, utilize the trace directories that are produced by the simulation. To carry out in-depth analysis and visualization, you can employ efficient tools such as Python, MATLAB, or Wireshark.

Performance Analysis Metrics

  1. Throughput: In a specific time period, the number of data which are shared through the network efficiently has to be evaluated. Generally, the throughput is assessed in bits per second (bps).
  2. Latency: To move from the source to the destination, the time that is required for a packet is assessed. Processing delay, transmission delay, and propagation delay could be encompassed.
  3. Packet Loss: The total count of packets which are lost at the time of sharing is evaluated in this metric. For analyzing the network credibility, this metric is considered as very crucial.
  4. Energy Utilization: At the time of simulation, the total energy that is utilized by the network nodes is evaluated in energy consumption metric. To assess the effectiveness of energy-efficient approaches, this metric is most significant.
