How to Implement network Energy Consumption in OMNeT++
To implement the network energy consumption in OMNeT++ has includes modelling and mimicking how network nodes consume energy while their operations. It can be significant for learning the influence of energy usage on network performance and lifetime. Below is a detailed approaches on how to set up and mimic network energy consumption in OMNeT++:
Step-by-Step Implementations:
- Understand Network Energy Consumption
Network energy consumption denotes to the energy used by network nodes for several operations like data transmission, reception, and processing. It can contain:
- Transmitting Data: Energy needed to send data through the network.
- Receiving Data: Energy required to receive and process incoming data.
- Idle State: Energy consumed when the node is not actively sending or receiving but is still powered on.
- Set up OMNeT++ Environment
Make certain OMNeT++ and the INET framework are installed. OMNeT++ offers the simulation situation, and INET contains network models we can extend for energy consumption.
- Create a New OMNeT++ Project
Open OMNeT++ and generate a new project for energy consumption simulation.
- Define Network Topology
Describe the network components and their connectivity in .ned files. Comprise parameters for energy consumption in the node designations.
Example:
network EnergyConsumptionNetwork
{
submodules:
node1: EnergyConsumingNode {
@display(“i=node”);
}
node2: EnergyConsumingNode {
@display(“i=node”);
}
connections:
node1.out –> node2.in;
}
- Define Energy Consuming Node
State a node module that models energy consumption. Describe parameters for energy usage during several states.
Example:
simple EnergyConsumingNode
{
parameters:
double txEnergy = 0.5mJ; // Energy per transmission
double rxEnergy = 0.3mJ; // Energy per reception
double idleEnergy = 0.1mJ; // Energy per idle period
double maxEnergy = 10.0mJ; // Maximum energy capacity
gates:
inout in;
inout out;
}
- Implement Energy Consumption Logic
Execute the logic for energy consumption in the node’s C++ code. This contains energy used for transmission, reception, and idle periods.
Example:
class EnergyConsumingNode : public cSimpleModule
{
private:
double txEnergy;
double rxEnergy;
double idleEnergy;
double maxEnergy;
double currentEnergy;
protected:
virtual void initialize() override;
virtual void handleMessage(cMessage *msg) override;
public:
void consumeEnergy(double amount);
};
void EnergyConsumingNode::initialize()
{
txEnergy = par(“txEnergy”);
rxEnergy = par(“rxEnergy”);
idleEnergy = par(“idleEnergy”);
maxEnergy = par(“maxEnergy”);
currentEnergy = maxEnergy;
}
void EnergyConsumingNode::handleMessage(cMessage *msg)
{
if (msg->isSelfMessage()) {
// Handle self messages (e.g., timer events)
consumeEnergy(idleEnergy);
} else {
// Handle incoming messages
consumeEnergy(rxEnergy);
// Process and forward message
consumeEnergy(txEnergy);
}
}
void EnergyConsumingNode::consumeEnergy(double amount)
{
if (currentEnergy >= amount) {
currentEnergy -= amount;
} else {
// Handle energy depletion (e.g., node inactivity)
currentEnergy = 0;
// Optionally: Send notification or change node state
}
}
- Configure Simulation Parameters
Oversee the omnetpp.ini file to set parameters associated to energy consumption for the nodes.
Example:
[Config EnergyConsumptionNetwork]
network = EnergyConsumptionNetwork
**.node1.txEnergy = 0.6mJ
**.node1.rxEnergy = 0.4mJ
**.node1.idleEnergy = 0.2mJ
**.node1.maxEnergy = 15.0mJ
- Run the Simulation
Compile and run the simulation. Monitor how energy consumption affects node behaviour and network performance.
- Analyse Results
Estimate the performance based on metrics like:
- Energy Efficiency: Extent of energy consumed per unit of work done.
- Node Lifetime: How long nodes remain operational previously depleting their energy.
- Network Performance: Influence on throughput, delay, and connectivity.
To visualize energy consumption and its effects on the network by using OMNeT++’s analysis tools and plotting functions.
