How to Calculate Network Energy Utilization in omnet++

To calculate the network energy utilization in OMNeT++ has needs to encompass following the energy consumption of network nodes like sensors, routers during the simulation. This is usually needs using or extending existing modules to observe energy usage as nodes transmit, receive, and process data.

The given steps are helps to calculate network energy utilization in OMNeT++:

Step-by-Step Implementations:

1. Use an Energy Framework:

• OMNeT++ does not have a built-in energy model, but we can use being frameworks like INET or MiXiM which offer energy models. This frameworks are contain modules for energy consumption tracking, like SimpleEnergyStorage, EnergyConsumer, and EnergySource.

2. Integrate Energy Model:

• Integrate an energy model into the node’s structure. For example, using the SimpleBattery model in INET:

NED File Example:

import inet.power.simple.SimpleBattery;

import inet.power.consumer.EnergyConsumer;

module Node

{

submodules:

battery: SimpleBattery {

parameters:

capacity = 10000mAh; // define battery capacity

}

energyConsumer: EnergyConsumer {

parameters:

consumptionRate = 0.001W; // define power consumption rate

}

connections:

// define connections

}

3. Configure Energy Parameters:

• Set the parameters for energy consumption, like the power consumed during transmission (Tx), reception (Rx), and idle states.

Example Configuration in omnetpp.ini:

*.node[*].battery.capacity = 5000mAh

*.node[*].energyConsumer.consumptionRate = 0.001W

4. Track Energy Consumption:

• Track energy consumption over time. The energy model modules commonly do this by subtracting energy based on the activity of the node like transmitting or receiving packets.
• Energy consumption is usually calculated using:

Energy Consumed=Power Consumption×Time\text{Energy Consumed} = \text{Power Consumption} \times \text{Time}Energy Consumed=Power Consumption×Time

• In the simulation, energy consumption for several states can be accumulated:

double txEnergy = txPowerConsumption * txDuration;

double rxEnergy = rxPowerConsumption * rxDuration;

double idleEnergy = idlePowerConsumption * idleDuration;

double totalEnergyConsumed = txEnergy + rxEnergy + idleEnergy;

5. Calculate Overall Energy Utilization:

• To compute the overall energy utilization of the network, we can add the energy consumed by all nodes.

double networkEnergyUtilization = 0;

for (int i = 0; i < numNodes; i++) {

networkEnergyUtilization += nodes[i].getTotalEnergyConsumed();

}

double averageEnergyUtilization = networkEnergyUtilization / numNodes;

• Note down this value using OMNeT++’s statistics recording feature.

recordScalar(“Total Network Energy Utilization”, networkEnergyUtilization);

recordScalar(“Average Node Energy Utilization”, averageEnergyUtilization);

6. Simulation and Analysis:

• Run the simulation with the configured energy model.
• The recorded energy values will deliver insights into how much energy was used by each node and the network as a whole at the end of the simulation.

7. Post-Processing:

• Analyse the recorded energy data to know network energy efficiency. We can other process the data using external tools like Python, R, or MATLAB if detailed analysis is essential.

Example Output in omnetpp.ini:

To get outputs related to energy consumption:

*.node[*].energyConsumer.recordScalar(“energyConsumed”);

*.node[*].battery.recordScalar(“remainingEnergy”);

*.node[*].energyConsumer.recordScalar(“totalEnergyUtilization”);

8. Consider Advanced Scenarios:

• If the network encompasses changing energy consumption rates like due to numerous packet sizes, distances, or environmental conditions, make sure that these factors are accounted for in the energy model and calculations.

Finally, we are know the concepts and steps to calculate the Energy Utilization in OMNeT++ using INET or MiXiM framework. We will offer more ideas and informations depends on your needs.
