   • Use the model for BasicEnergySourceHelper and DeviceEnergyModelHelper.
4. Install Applications:
   • Use applications like UdpEchoApplication or custom applications for build congestion.
5. Data Collection and Processing:
   • Apply the gateways or edge devices for aggregate the data from sensors.

Step 5: Simulate and Trace

1. Set Simulation Parameters:
   • Describe the replication of duration using Simulator::Stop().
2. Enable Tracing:
   • Use the assure trace like AsciiTrace, PcapTrace, and FlowMonitor for performance metrics.
3. Run the Simulation:
   • Perform the replication script using ./waf.

Step 6: Analyze Results

Step 7: Document and Present

1. Prepare Documentation:
   • Store the document for simulation setup, outcomes, and observations.
2. Create Visualizations:
   • Use the tool for charts, graphs, and tables in present the detection of efficiently.

Example NS3 Script for IIoT using Zigbee

Here’s an sample for replicating an IIoT network using Zigbee such as IEEE 802.15.4:

#include “ns3/internet-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

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

// Step 1: Create nodes

NodeContainer sensorNodes, gatewayNode;

sensorNodes.Create(5); // 5 sensors

gatewayNode.Create(1); // 1 gateway

// Step 2: Configure Zigbee (IEEE 802.15.4)

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

ipv4.Assign(sensorDevices);

// Step 5: Configure traffic application

UdpEchoServerHelper echoServer(9); // Server on port 9

ApplicationContainer serverApps = echoServer.Install(gatewayNode.Get(0));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(Ipv4Address(“10.1.1.1”), 9);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(100));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.5)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(64));

ApplicationContainer clientApps = echoClient.Install(sensorNodes.Get(0));
