How to Implement network Energy Harvesting in OMNeT++

To implement the network energy harvesting using OMNeT++ has encompasses mimicking networks where nodes can harvest energy from their situation, like wind, solar, or other sources, and handling the use of this energy for network operations. Below is a procedure to setting up and emulating energy harvesting networks in OMNeT++:

Step-by-Step Implementations:

1. Understand Energy Harvesting in Networks

• Energy Harvesting permits network nodes to gather energy from renewable sources to extend their operational lifetime and decrease dependency on old power sources. Key features comprise energy collection rates, storage, and energy consumption.

2. Set up OMNeT++ Environment

• Make certain OMNeT++ and the INET framework are installed. We may also want extra libraries or custom code to mimic energy harvesting.

3. Create a New OMNeT++ Project

• Open OMNeT++ and generate a new project for energy harvesting network simulation.

4. Define Network Topology

• Create Network Modules:
  • Describe the network components like nodes, base stations in .ned files, containing parameters for energy harvesting.
  • Example:

network EnergyHarvestingNetwork

{

submodules:

node1: EnergyHarvestingNode {

@display(“i=node”);

}

node2: EnergyHarvestingNode {

@display(“i=node”);

}

connections:

node1.out –> node2.in;

}

5. Define Energy Harvesting Node

• Create Node Modules:
  • State the energy harvesting characteristics like collection rate, storage capacity, and consumption.
  • Example:

simple EnergyHarvestingNode

{

parameters:

double harvestRate = 10mW;  // Rate at which energy is harvested

double storageCapacity = 1000mWh; // Maximum energy storage

double consumptionRate = 5mW; // Rate at which energy is consumed

gates:

inout in;

inout out;

}

6. Implement Energy Harvesting Logic

• Create Node Behaviour:
  • Execute energy harvesting, storage, and consumption logic in C++.
  • Example:

void EnergyHarvestingNode::handleMessage(cMessage *msg)

{

// Energy harvesting logic

double harvestedEnergy = harvestRate * simTime().dbl(); // Energy harvested over time

energyStored += harvestedEnergy;

if (energyStored > storageCapacity)

energyStored = storageCapacity;

// Energy consumption logic

if (energyStored > consumptionRate) {

energyStored -= consumptionRate;

// Process incoming messages

// Forward messages if needed

} else {

// Not enough energy to process messages

// Implement energy-saving behavior

}

}

7. Configure Energy Harvesting Parameters

• Edit the omnetpp.ini File:
  • Simulate parameters connected to energy harvesting and network behaviour.
  • Example:

[Config EnergyHarvestingNetwork]

network = EnergyHarvestingNetwork

**.node1.harvestRate = 15mW

**.node1.storageCapacity = 2000mWh

**.node1.consumptionRate = 10mW

8. Run the Simulation

• Compile and Execute:
  • Form the project and run the simulation.
  • Monitor how energy harvesting affects node act and network operation.

9. Analyse Results

• Evaluate Metrics:
  • Evaluate performance metrics like energy consumption, energy harvesting efficiency, network lifetime, and throughput.
  • To visualize and interpret the simulation results by using OMNeT++’s tools.

Additional Considerations

• Energy Harvesting Models: Consider numerous models for energy harvesting like solar, wind and how they impact the network.
• Energy Storage: Execute several kinds of energy storage such as batteries, supercapacitors and their features.
• Energy Efficiency: Contain mechanisms for optimizing energy use and extending the network’s operational lifetime.
