How to Implement Network Power allocation in ns3

To implement the network power allocation in ns3 has numerous steps to follow and the simulation of ns3 is discrete-event network simulator that usually used for research and educational purpose.

The given below is the detailed procedures on how to implement the network power allocation in ns3:

Step-by-Step Implementation:

Step 1: Setup ns3 Environment

1. Install ns3: Make sure ns3 is installed in the computer.

git clone https://gitlab.com/nsnam/ns-3-dev.git

cd ns-3-dev

./waf configure

./waf build

Step 2: Understand ns3 Structure

The ns3 is structured into modules, each handling various aspects of network simulation. Key modules for power allocation contain:

• Core: Base functionalities.
• Network: Network components.
• Internet: Internet protocols.
• Mobility: Node mobility models.
• Wifi/Lte: Wireless models.

Step 3: Create a Custom Application or Helper

To implement power allocation, we need to make a custom application or modify an existing one to take in power control algorithms.

1. Create a Custom Application:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/wifi-module.h”

using namespace ns3;

class PowerAllocationApp : public Application

{

public:

PowerAllocationApp();

virtual ~PowerAllocationApp();

void Setup(Ptr<Node> node, double power);

private:

virtual void StartApplication(void);

virtual void StopApplication(void);

Ptr<Node> m_node;

double m_power;

};

PowerAllocationApp::PowerAllocationApp() : m_node(0), m_power(0) {}

PowerAllocationApp::~PowerAllocationApp() {}

void PowerAllocationApp::Setup(Ptr<Node> node, double power)

{

m_node = node;

m_power = power;

}

void PowerAllocationApp::StartApplication(void)

{

if (m_node)

{

Ptr<WifiNetDevice> wifiDevice = DynamicCast<WifiNetDevice>(m_node->GetDevice(0));

if (wifiDevice)

{

Ptr<WifiPhy> wifiPhy = wifiDevice->GetPhy();

wifiPhy->SetTxPowerStart(m_power);

wifiPhy->SetTxPowerEnd(m_power);

}

}

}

void PowerAllocationApp::StopApplication(void)

{

// Clean up

}

Create a Helper Function:

class PowerAllocationHelper

{

public:

PowerAllocationHelper();

void Install(Ptr<Node> node, double power);

private:

Ptr<PowerAllocationApp> m_app;

};

PowerAllocationHelper::PowerAllocationHelper() : m_app(CreateObject<PowerAllocationApp>()) {}

void PowerAllocationHelper::Install(Ptr<Node> node, double power)

{

m_app->Setup(node, power);

node->AddApplication(m_app);

m_app->SetStartTime(Seconds(1.0));

m_app->SetStopTime(Seconds(10.0));

}

Step 4: Modify Simulation Script

Integrate the custom application into your simulation script.

#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 “power-allocation-helper.h”

using namespace ns3;

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

{

// Set up the simulation environment

NodeContainer wifiStaNodes;

wifiStaNodes.Create(1);

NodeContainer wifiApNode;

wifiApNode.Create(1);

YansWifiChannelHelper channel = YansWifiChannelHelper::Default();

YansWifiPhyHelper phy = YansWifiPhyHelper::Default();

phy.SetChannel(channel.Create());

WifiHelper wifi = WifiHelper::Default();

wifi.SetRemoteStationManager(“ns3::AarfWifiManager”);

WifiMacHelper mac;

Ssid ssid = Ssid(“ns-3-ssid”);

mac.SetType(“ns3::StaWifiMac”, “Ssid”, SsidValue(ssid), “ActiveProbing”, BooleanValue(false));

NetDeviceContainer staDevices = wifi.Install(phy, mac, wifiStaNodes);

mac.SetType(“ns3::ApWifiMac”, “Ssid”, SsidValue(ssid));

NetDeviceContainer apDevices = wifi.Install(phy, mac, wifiApNode);

MobilityHelper mobility;

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

mobility.Install(wifiApNode);

mobility.Install(wifiStaNodes);

InternetStackHelper stack;

stack.Install(wifiApNode);

stack.Install(wifiStaNodes);

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer apInterfaces = address.Assign(apDevices);

Ipv4InterfaceContainer staInterfaces = address.Assign(staDevices);

// Install Power Allocation Application

PowerAllocationHelper powerAllocationHelper;

powerAllocationHelper.Install(wifiStaNodes.Get(0), 10.0); // Set transmit power to 10 dBm

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

Step 5: Run the Simulation

1. Compile the Simulation:

./waf configure –enable-examples

./waf build

Run the Simulation:

./waf –run <your-simulation-script>

Step 6: Analyse Results

After running the simulation, analyse the results to evaluate the performance of your power allocation scheme. We need to collect metrics like signal-to-noise ratio (SNR), packet delivery ratio (PDR), and energy consumption.

Additional Tips:

• Debugging: Use ns3 logging to debug your code (NS_LOG_* macros).
• Validation: Validate your power allocation algorithm with different network scenarios and configurations.

Conclusively, we all get the knowledge about how the network power allocation is simulated and evaluate the outcomes by using the ns3 simulator. More information regarding the network power allocation and implementation support you can call us we will provide complete support.
