Step-by-Step Guide to Implement Biomedical Networks in ns-3

1. Set Up Your Development Environment

1. Install ns-3:
   • Follow the official ns-3 installation guide.
2. Install Required Modules:
   • Ensure you have all necessary ns-3 modules installed, such as Internet, WiFi, Mobility, Energy, and Applications modules.

2. Create a Basic Biomedical Network Simulation Script

Here we offer the sample script to set up a biomedical network environment using ns-3:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/wifi-module.h”

#include “ns3/mobility-module.h”

#include “ns3/applications-module.h”

#include “ns3/energy-module.h”

#include “ns3/flow-monitor-module.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE (“BiomedicalNetworkExample”);

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

{

  // Set simulation parameters

  double simTime = 60.0; // Simulation time in seconds

  uint32_t numDevices = 10;

  CommandLine cmd;

  cmd.AddValue(“simTime”, “Simulation time”, simTime);

  cmd.AddValue(“numDevices”, “Number of devices”, numDevices);

  cmd.Parse(argc, argv);

  // Create nodes

  NodeContainer medicalDevices;

  medicalDevices.Create(numDevices);

  // Set up Wi-Fi network for medical devices

  WifiHelper wifi;

  wifi.SetStandard(WIFI_PHY_STANDARD_80211n);

  YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

  YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

  wifiPhy.SetChannel(wifiChannel.Create());

  WifiMacHelper wifiMac;

  wifiMac.SetType(“ns3::AdhocWifiMac”);

  NetDeviceContainer deviceNetDevices;

  deviceNetDevices = wifi.Install(wifiPhy, wifiMac, medicalDevices);

  // Install the Internet stack on all nodes

  InternetStackHelper stack;

  stack.Install(medicalDevices);

  // Assign IP addresses to devices

  Ipv4AddressHelper address;

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

  Ipv4InterfaceContainer deviceInterfaces = address.Assign(deviceNetDevices);

  // Set up mobility

  MobilityHelper mobility;

  mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,

                                “MinX”, DoubleValue(0.0),

                                “MinY”, DoubleValue(0.0),

                                “GridWidth”, UintegerValue(5),

                                “LayoutType”, StringValue(“RowFirst”));

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

  mobility.Install(medicalDevices);

  // Set up energy model for medical devices

  BasicEnergySourceHelper basicSourceHelper;

  basicSourceHelper.Set(“BasicEnergySourceInitialEnergyJ”, DoubleValue(10000.0));

  EnergySourceContainer sources = basicSourceHelper.Install(medicalDevices);

  WifiRadioEnergyModelHelper radioEnergyHelper;

  DeviceEnergyModelContainer deviceModels = radioEnergyHelper.Install(deviceNetDevices, sources);

  // Create applications

  uint16_t port = 9;

  // Install a UDP echo server on the first medical device

  UdpEchoServerHelper echoServer(port);

  ApplicationContainer serverApp = echoServer.Install(medicalDevices.Get(0));

  serverApp.Start(Seconds(1.0));

  serverApp.Stop(Seconds(simTime));

  // Install a UDP echo client on each medical device

  for (uint32_t i = 1; i < numDevices; ++i)

  {

    UdpEchoClientHelper echoClient(deviceInterfaces.GetAddress(0), port);

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

    echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));

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

    ApplicationContainer clientApp = echoClient.Install(medicalDevices.Get(i));

    clientApp.Start(Seconds(2.0));

    clientApp.Stop(Seconds(simTime));

  }

  // Enable Flow Monitor

  FlowMonitorHelper flowmon;

  Ptr<FlowMonitor> monitor = flowmon.InstallAll();

  // Enable tracing

  wifiPhy.EnablePcap(“biomedical-network-example”, deviceNetDevices.Get(0));

  // Run the simulation

  Simulator::Stop(Seconds(simTime));

  Simulator::Run();

  // Print energy consumption statistics

  for (uint32_t i = 0; i < sources.GetN(); ++i)

  {

    Ptr<EnergySource> source = sources.Get(i);

    double remainingEnergy = source->GetRemainingEnergy();

    NS_LOG_UNCOND(“Device ” << i << ” remaining energy: ” << remainingEnergy << ” J”);

  }

  // Print flow monitor statistics

  monitor->SerializeToXmlFile(“biomedical-network-flowmon.xml”, true, true);

  Simulator::Destroy();

  return 0;

}
