6. Basic Example Simulation

Here’s a simple ttol NS3 script for replicate the mobile devices in a Wi-Fi network:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/mobility-module.h”

#include “ns3/wifi-module.h”

#include “ns3/internet-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

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

CommandLine cmd;

cmd.Parse(argc, argv);

// Create nodes for mobile devices

NodeContainer mobileNodes;

mobileNodes.Create(5); // 5 mobile nodes

// Set up mobility model for mobile devices

MobilityHelper mobility;

mobility.SetMobilityModel(“ns3::RandomWaypointMobilityModel”,

“Speed”, StringValue(“ns3::UniformRandomVariable[Min=1.0|Max=5.0]”),

“Pause”, StringValue(“ns3::ConstantRandomVariable[Constant=2.0]”),

“PositionAllocator”, StringValue(“ns3::RandomRectanglePositionAllocator”));

mobility.SetPositionAllocator(“ns3::RandomRectanglePositionAllocator”,

“X”, StringValue(“ns3::UniformRandomVariable[Min=0.0|Max=100.0]”),

“Y”, StringValue(“ns3::UniformRandomVariable[Min=0.0|Max=100.0]”));

mobility.Install(mobileNodes);

// Configure Wi-Fi

WifiHelper wifi;

wifi.SetStandard(WIFI_PHY_STANDARD_80211b);

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

wifiPhy.SetChannel(wifiChannel.Create());

WifiMacHelper wifiMac;

wifiMac.SetType(“ns3::AdhocWifiMac”);

NetDeviceContainer devices = wifi.Install(wifiPhy, wifiMac, mobileNodes);

// Install Internet stack

InternetStackHelper internet;

internet.Install(mobileNodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

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

ipv4.Assign(devices);

// Create traffic applications

UdpEchoServerHelper echoServer(9);

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

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

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

echoClient.SetAttribute(“MaxPackets”, UintegerValue(5));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

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

ApplicationContainer clientApps = echoClient.Install(mobileNodes.Get(1));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

7. Expand the Simulation

• Mobility Models:
  • Enhance the further realistic designs such as vehicular mobility for instance SUMO.
• Network Technologies:
  • The network topologies are replicate the LTE or 5G networks.
• Traffic Patterns:
  • It contains the video streaming for file transfer, or IoT sensor data.
• Resource Management:
  • Apply the dynamic resource allocation or offloading environments.

8. Analyze Performance Metrics

• Throughput: The percentages of data transmission are calculated.
• Latency: Estimate the end-to-end delays.
• Packet Delivery Ratio (PDR): Examine the reliability for packet delivery.
• Energy Consumption: It allocates the energy effectiveness for mobile devices.

9. Advanced Features

• Mobile Cloud Computing (MCC):
  • It replicate the offloading tasks from mobile nodes for cloud servers.
• Mobile Edge Computing (MEC):
  • Establish the edge nodes for low-latency processing.
• Security:
