How to Begin Implement Network Power Consumption in NS3

To begin implementing and examining the Network Power Consumption using NS3, we need to follow provided stepwise approach:

Steps to Begin Implement Network Power Consumption in NS3

  1. Understand the Power Consumption Concept

In a network, power consumption based on:

  • Idle and sleep states of network devices.
  • Transmission power.
  • Energy patterns are used for measuring the energy consumption.
  • Applications are generating traffic and its operational models.

Energy Framework is leveraged for designing and examining the power consumption in ns3.

  1. Set Up Your Environment
  • Make sure that we have installed ns3 on the computer.
  • We can get more knowledge about Energy Framework using ns3, which is available in the Wi-Fi and LTE modules.
  1. Include Energy Models

In ns3, Energy Framework shows energy consumption for devices. It needs to:

  1. Energy Source: Provide energy to the device.
  2. Device Energy Model: Estimate the energy consumption.

For instance:

  • BasicEnergySource: Designs an energy source of device.
  • WifiRadioEnergyModel: Models energy expended by Wi-Fi devices.
  1. Define Network Nodes

Make network nodes and allocate them mobility:

NodeContainer nodes;

nodes.Create(10); // Create 10 nodes

MobilityHelper mobility;

mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,

“MinX”, DoubleValue(0.0),

“MinY”, DoubleValue(0.0),

“DeltaX”, DoubleValue(50.0),

“DeltaY”, DoubleValue(50.0),

“GridWidth”, UintegerValue(3),

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

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

mobility.Install(nodes);

  1. Set Up Wi-Fi Communication

We can install Wi-Fi devices and protocols for communication:

WifiHelper wifi;

wifi.SetStandard(WIFI_PHY_STANDARD_80211n);

YansWifiPhyHelper phy = YansWifiPhyHelper::Default();

YansWifiChannelHelper channel = YansWifiChannelHelper::Default();

phy.SetChannel(channel.Create());

WifiMacHelper mac;

mac.SetType(“ns3::AdhocWifiMac”);

NetDeviceContainer devices = wifi.Install(phy, mac, nodes);

InternetStackHelper stack;

stack.Install(nodes);

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces = address.Assign(devices);

  1. Add Energy Models

Add an energy source and a Wi-Fi energy model to every node:

BasicEnergySourceHelper energySourceHelper;

energySourceHelper.Set(“BasicEnergySourceInitialEnergyJ”, DoubleValue(100.0)); // Initial energy in Joules

WifiRadioEnergyModelHelper radioEnergyHelper;

radioEnergyHelper.Set(“TxCurrentA”, DoubleValue(0.017)); // Current in Amperes during transmission

radioEnergyHelper.Set(“RxCurrentA”, DoubleValue(0.013)); // Current in Amperes during reception

EnergySourceContainer energySources = energySourceHelper.Install(nodes);

DeviceEnergyModelContainer deviceModels = radioEnergyHelper.Install(devices, energySources);

  1. Install Applications

Integrate the applications for making network traffic:

UdpEchoServerHelper echoServer(9);

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

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(interfaces.GetAddress(0), 9);

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

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.01)));

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

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

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

  1. Monitor Energy Consumption

During the simulation, observe the levels of energy:

Ptr<BasicEnergySource> source = DynamicCast<BasicEnergySource>(energySources.Get(0));

Simulator::Schedule(Seconds(5.0), &BasicEnergySource::UpdateEnergySource, source);

Simulator::Schedule(Seconds(5.0), &BasicEnergySource::GetRemainingEnergy, source);

source->TraceConnectWithoutContext(“RemainingEnergy”, MakeCallback(&PrintEnergy));

Example Callback to Print Energy Levels:

void PrintEnergy(double oldValue, double newValue) {

std::cout << “Remaining energy: ” << newValue << “J” << std::endl;

}

  1. Analyze and Visualize Results
  • Log Energy Levels: Observe the energy utilization over time to apply tracing or custom callbacks.
  • Visualize Results:
    • Transfer energy information into files for visualization.
    • Make use of ns3 tools such as Gnuplot for graphical representation.
  1. Experiment with Different Configurations
  • Modify transmission power such as TxPowerStart, TxPowerEnd to learn energy utilization.
  • Fine-tune node density and traffic models.
  • Experiment other energy patterns such as DeviceEnergyModel for LTE or custom energy models.
  1. Run and Debug the Simulation

Finally, execute the simulation and confirm energy consumption models:

Simulator::Run();

Simulator::Destroy();

Detailed, sequential steps for implementing and examining the Network Power Consumption using NS3 environment have been offered. We’re ready to add more details and additional concepts, if necessary.
