To implement the network energy harvesting in ns3, we need to develop the energy harvesting so we demonstrate the energy sources, harvesting processes, and energy consumption of network devices.
Now we are going to deliver the detailed approach on how to implement the network energy harvesting in ns3:
Step-by-Step Implementation:
Step 1: Set Up the ns3 Environment
- Install ns3: Make certain ns3 is installed in the system.
sudo apt-get update
sudo apt-get install ns3
Create a New ns3 Project: Create a directory for your new project within the ns3 workspace.
cd ns-3
mkdir scratch/energy-harvesting-project
Step 2: Extend ns3 with Energy Harvesting Capabilities
- Create Energy Models: To improve the models to signify energy sources like solar, wind, energy harvesting processes, and energy storage.
- Modify Node Energy Models: Extend ns3’s existing energy models to account for energy harvesting. ns3 has a basic energy module that we need to extend.
Step 3: Develop the Energy Harvesting Model
- Energy Source Model: Create a model for the energy source. For example, a solar energy model could depend on time of day and weather conditions.
class SolarEnergySource : public EnergySource {
public:
SolarEnergySource();
virtual ~SolarEnergySource();
void UpdateEnergyHarvested();
private:
double m_energyHarvested;
Time m_lastUpdateTime;
};
SolarEnergySource::SolarEnergySource() : m_energyHarvested(0.0) {
m_lastUpdateTime = Simulator::Now();
}
SolarEnergySource::~SolarEnergySource() {}
void SolarEnergySource::UpdateEnergyHarvested() {
Time now = Simulator::Now();
double timeElapsed = (now – m_lastUpdateTime).GetSeconds();
// Example: Energy harvested depends on time of day
double energyHarvested = timeElapsed * GetCurrentSolarIntensity();
m_energyHarvested += energyHarvested;
m_lastUpdateTime = now;
}
Energy Consumption Model: Extend the existing energy consumption models to include energy harvesting capabilities.
class HarvestingDeviceEnergyModel : public DeviceEnergyModel {
public:
HarvestingDeviceEnergyModel();
virtual ~HarvestingDeviceEnergyModel();
void UpdateEnergyConsumption();
void UpdateEnergyHarvesting();
private:
Ptr<SolarEnergySource> m_energySource;
double m_energyConsumed;
};
HarvestingDeviceEnergyModel::HarvestingDeviceEnergyModel() : m_energyConsumed(0.0) {
m_energySource = CreateObject<SolarEnergySource>();
}
HarvestingDeviceEnergyModel::~HarvestingDeviceEnergyModel() {}
void HarvestingDeviceEnergyModel::UpdateEnergyConsumption() {
// Example: Energy consumption based on device activity
double energyConsumed = CalculateEnergyConsumption();
m_energyConsumed += energyConsumed;
}
void HarvestingDeviceEnergyModel::UpdateEnergyHarvesting() {
m_energySource->UpdateEnergyHarvested();
}
Step 4: Integrate Energy Harvesting into ns3 Simulation
- Create a New Simulation Script: Create a new script in your scratch directory to implement the simulation scenario.
// energy-harvesting-project.cc
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/point-to-point-module.h”
#include “ns3/applications-module.h”
#include “ns3/energy-module.h”
#include “solar-energy-source.h”
#include “harvesting-device-energy-model.h”
using namespace ns3;
int main(int argc, char *argv[]) {
// Set up the simulation
NodeContainer nodes;
nodes.Create(2);
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = pointToPoint.Install(nodes);
InternetStackHelper stack;
stack.Install(nodes);
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
// Install energy models
EnergySourceContainer sources;
Ptr<SolarEnergySource> solarSource = CreateObject<SolarEnergySource>();
sources.Add(solarSource);
DeviceEnergyModelContainer deviceModels;
Ptr<HarvestingDeviceEnergyModel> harvestingModel = CreateObject<HarvestingDeviceEnergyModel>();
harvestingModel->SetEnergySource(solarSource);
deviceModels.Add(harvestingModel);
// Attach energy models to nodes
nodes.Get(0)->AggregateObject(solarSource);
nodes.Get(0)->AggregateObject(harvestingModel);
// Run the simulation
Simulator::Stop(Seconds(10.0));
Simulator::Run();
Simulator::Destroy();
return 0;
}
- Implement the Energy Update Mechanism: Guarantee that energy consumption and harvesting are periodically updated during the simulation.
Step 5: Run and Validate the Simulation
- Build the Project: Build your ns3 project to ensure that everything is linked correctly.
./waf build
Run the Simulation: Run your simulation script and observe the results.
./waf –run scratch/energy-harvesting-project
Validate and Analyse Results: Validate the performance of the energy harvesting by analysing the simulation results. Compare the energy levels and device performance under different scenarios.
As we discussed earlier about how the network energy harvesting will perform in ns3 framework and we help to deliver additional information about how the network energy harvesting will adapt in different simulations.
