How to Implement Wireless Power Transfer Networks in OMNeT++

To implement Wireless Power Transfer (WPT) Networks in OMNeT++ has needs to design and emulate a network that the nodes can wirelessly transfer power to each other. This type of network is very helpful for application such as wireless charging of devices or powering sensor nodes in an IoT setup. The given below is the brief procedure on how to implement the wireless power transfer network in OMNeT++ using the INET framework:

Step-by-Step Implementation

Install OMNeT++ and INET Framework

Make sure we have OMNeT++ and the INET Framework installed.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project. Name the project like WPTNetworkSimulation.

Define the Network Topology

Generate a new NED file to describe the network topology that contains wireless nodes capable of power transfer.

Example: WPT Network Topology (WPTNetwork.ned)

package wptnetwork;

import inet.node.inet.StandardHost;

import inet.node.inet.WirelessHost;

network WPTNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

node1: WirelessHost {

@display(“p=100,300”);

}

node2: WirelessHost {

@display(“p=300,300”);

}

node3: WirelessHost {

@display(“p=500,300”);

}

connections allowunconnected:

}

Configure the Simulation

Create an OMNeT++ initialization file to configure the parameters of the simulation.

Example: Configuration File (omnetpp.ini)

network = wptnetwork.WPTNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Wireless Node Configuration

*.node*.numApps = 1

*.node*.app[0].typename = “WPTApp”

# IP Address Configuration

*.node1.ipv4.config = xmldoc(“node1.xml”)

*.node2.ipv4.config = xmldoc(“node2.xml”)

*.node3.ipv4.config = xmldoc(“node3.xml”)

Create IP Address Configuration Files

Generate XML files to describe the IP address configuration for each node.

Example: IP Configuration File for node1 (node1.xml)

</interface>

</config>

Example: IP Configuration File for node2 (node2.xml)

</interface>

</config>

Example: IP Configuration File for node3 (node3.xml)

</interface>

</config>

Implement WPT Application Logic

To simulate wireless power transfer, we need to execute the logic for power transfer and consumption.

Example: WPT Application (Pseudo-Code)

#include <omnetpp.h>

using namespace omnetpp;

class WPTApp : public cSimpleModule

{

private:

double energyLevel;

double powerTransferRate;

double powerConsumptionRate;

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

virtual void handlePowerTransfer();

public:

WPTApp();

virtual ~WPTApp();

};

Define_Module(WPTApp);

WPTApp::WPTApp()

{

// Constructor code

}

WPTApp::~WPTApp()

{

// Destructor code

}

void WPTApp::initialize()

{

// Initialization code

energyLevel = par(“initialEnergyLevel”);

powerTransferRate = par(“powerTransferRate”);

powerConsumptionRate = par(“powerConsumptionRate”);

scheduleAt(simTime() + 1, new cMessage(“handlePowerTransfer”));

}

void WPTApp::handleMessage(cMessage *msg)

{

if (strcmp(msg->getName(), “handlePowerTransfer”) == 0) {

handlePowerTransfer();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void WPTApp::handlePowerTransfer()

{

// Logic to transfer power to nearby nodes

// This is a placeholder. Actual implementation will depend on the specific WPT algorithm.

energyLevel -= powerConsumptionRate;

// Assuming some power transfer logic here

energyLevel += powerTransferRate;

}

Add Power Transfer Parameters

Define parameters for the power transfer and consumption rates in the NED file.

Example: Add Parameters to NED File (WPTNetwork.ned)

package wptnetwork;

import inet.node.inet.StandardHost;

import inet.node.inet.WirelessHost;

network WPTNetwork

{

parameters:

@display(“bgb=800,400”);

double initialEnergyLevel = default(1000); // Initial energy level of nodes

double powerTransferRate = default(10); // Power transfer rate

double powerConsumptionRate = default(5); // Power consumption rate

submodules:

node1: WirelessHost {

@display(“p=100,300”);

initialEnergyLevel = 1000;

powerTransferRate = 10;

powerConsumptionRate = 5;

}

node2: WirelessHost {

@display(“p=300,300”);

initialEnergyLevel = 1000;

powerTransferRate = 10;

powerConsumptionRate = 5;

}

node3: WirelessHost {

@display(“p=500,300”);

initialEnergyLevel = 1000;

powerTransferRate = 10;

powerConsumptionRate = 5;

}

connections allowunconnected:

}
