How to Implement Wireless Power Transfer Network in NS3

To begin executing a Wireless Power Transfer (WPT) Network using NS3 environment needs to replicate the wireless power transfer among the nodes for instance from a power transmitter to a receiver. NS3 doesn’t offer module for WPT, but we will want to replicate the WPT by designing energy transfer approaches with existing ns3 aspects such as energy patterns and custom extensions, we can follow these steps to get started.

Steps to Begin Wireless Power Transfer Network in NS3

1. Understand WPT Networks

• Wireless Power Transfer (WPT):
  • Technology utilized for wirelessly transmitting the power among a power source and a load.
  • It can be executed through inductive coupling, resonant coupling, or radio-frequency (RF) power transfer.
• Key Features to Simulate:
  • Power transfer efficiency and losses.
  • Energy harvesting model at the receiver.
  • Power transmitter and receiver nodes.

2. Set Up ns3 Environment

1. Install ns3:

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

cd ns-3-dev

./build.py

1. Confirm the installation:

./ns3 run hello-simulator

3. Choose Relevant Modules

• Energy Models:
  • NS3 has an energy framework as src/energy, which can be adjusted for WPT.
  • Modules contain energy sources like batteries and energy consumers.
• Wireless Communication Models:
  • Replicate the WPT interaction features to utilize Wi-Fi, LTE, or other wireless components.
• Custom Models:
  • Improve custom models for replicating an energy harvesting and transfer.

4. Plan the WPT Network Architecture

• Define Nodes:
  • We describe the power transmitter nodes.
  • Power receiver nodes including energy harvesting ability.
• Topology:
  • It functions on single transmitter to numerous receivers or several transmitters to multiple receivers.
• Key Metrics:
  • Energy harvested at the receiver.
  • Power transfer efficiency.
  • Communication delays as needed.

5. Write the Simulation Script
6. Include Required Headers

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/energy-module.h”

#include “ns3/wifi-module.h”

#include “ns3/applications-module.h”

1. Define Nodes

ns3::NodeContainer nodes;

nodes.Create(2); // One transmitter and one receiver

1. Set Up Wireless Communication

ns3::WifiHelper wifi;

wifi.SetStandard(ns3::WIFI_PHY_STANDARD_80211g);

ns3::WifiMacHelper mac;

ns3::WifiPhyHelper phy = ns3::WifiPhyHelper::Default();

phy.SetChannel(ns3::YansWifiChannelHelper::Default().Create());

mac.SetType(“ns3::AdhocWifiMac”);

ns3::NetDeviceContainer devices = wifi.Install(phy, mac, nodes);

1. Install Energy Models

// Install Energy Source

ns3::BasicEnergySourceHelper energySourceHelper;

energySourceHelper.Set(“BasicEnergySourceInitialEnergyJ”, ns3::DoubleValue(100.0));

ns3::EnergySourceContainer sources = energySourceHelper.Install(nodes);

// Install Energy Harvesting Device on Receiver Node

ns3::EnergyHarvestingDeviceHelper harvestingHelper;

harvestingHelper.Set(“HarvestingEfficiency”, ns3::DoubleValue(0.8)); // Efficiency of WPT

harvestingHelper.Set(“HarvestingUpdateInterval”, ns3::TimeValue(ns3::Seconds(0.1)));

harvestingHelper.Install(sources.Get(1)); // Install on receiver node

1. Set Up Applications

ns3::UdpEchoServerHelper echoServer(9);

ns3::ApplicationContainer serverApps = echoServer.Install(nodes.Get(1)); // Receiver

serverApps.Start(ns3::Seconds(1.0));

serverApps.Stop(ns3::Seconds(10.0));

ns3::UdpEchoClientHelper echoClient(ns3::Ipv4Address(“10.1.1.2”), 9);

echoClient.SetAttribute(“MaxPackets”, ns3::UintegerValue(1));

echoClient.SetAttribute(“Interval”, ns3::TimeValue(ns3::Seconds(1.0)));

echoClient.SetAttribute(“PacketSize”, ns3::UintegerValue(1024));

ns3::ApplicationContainer clientApps = echoClient.Install(nodes.Get(0)); // Transmitter

clientApps.Start(ns3::Seconds(2.0));

clientApps.Stop(ns3::Seconds(10.0));

1. Monitor Energy Levels

// Monitor energy levels during simulation

sources.Get(1)->TraceConnectWithoutContext(“RemainingEnergy”, MakeCallback([](double oldValue, double newValue) {

std::cout << “Remaining Energy: ” << newValue << “J\n”;

}));

1. Run the Simulation

ns3::Simulator::Run();

ns3::Simulator::Destroy();

6. Custom Extensions

To design realistic WPT, we can:

• Custom Energy Transfer Model:
  • Create a custom application or helper for replicating power transfer.
  • For instance, determine the received power since function of distance and effectiveness.
• Power Loss Modeling:
  • Deliberate the power losses by reason of path loss, misalignment, or interference.

7. Analyze Results

• Estimate the performance parameters such as:
  • Power transfer effectiveness.
  • Total energy sent.
  • Energy harvested at the receiver.
• Make use of ns3 tracing and logging tools:

ns3::AsciiTraceHelper ascii;

phy.EnableAsciiAll(ascii.CreateFileStream(“wpt-network.tr”));

phy.EnablePcapAll(“wpt-network”);

8. Visualize the Simulation

• Visualize the topology and communications with NetAnim tools.
• Enable .pcap files with Wireshark tools for detailed analysis.

9. Iterate and Enhance

• Integrate numerous transmitters or receivers.
• Add mobility patterns for nodes.
• Discover furthered topics such as beamforming or adaptive power control for enhance the implementation.
