How to Implement Green Networking in OMNeT++

To implement the Green Networking in OMNeT++ encompasses planning and put on network protocols and formations that purpose to decrease energy consumption and increase the energy proficiency. It is through the modelling energy-aware network components and protocols. Given below is an implementations steps to the way that method:

Step-by-Step Implementations:

1. Understand the Basics of Green Networking

The purpose of the Green Networking in the networking infrastructure to reduce energy consumption. It can be reached over techniques like energy-efficient routing, efficient resource allocation, sleep modes for network devices, and adaptive link rates.

2. Install OMNeT++ and INET Framework

Make sure the OMNeT++ and the INET Framework is installed.

3. Create a New OMNeT++ Project

1. Open OMNeT++ IDE: Start the OMNeT++ IDE.
2. Create a New Project: Go to File -> New -> OMNeT++ Project. Put the project like GreenNetworkingSimulation.

4. Define the Network Topology

To make a new NED file to define the network topology, containing nodes and routers.

Example: Green Networking Topology (GreenNetwork.ned)

package greennetworking;

import inet.node.inet.StandardHost;

import inet.node.inet.Router;

network GreenNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

node1: StandardHost {

@display(“p=100,300”);

}

node2: StandardHost {

@display(“p=300,300”);

}

router: Router {

@display(“p=200,200”);

}

connections:

node1.ethg++ <–> Eth10M <–> router.ethg++;

node2.ethg++ <–> Eth10M <–> router.ethg++;

}

5. Configure the Simulation

To innovate an OMNeT++ initialization file to configure the constraints of the simulation.

Example: Configuration File (omnetpp.ini)

[General]

network = greennetworking.GreenNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.node*.numApps = 1

*.node*.app[0].typename = “UdpBasicApp”

*.node*.app[0].destAddresses = “router”

*.node*.app[0].destPort = 5000

*.node*.app[0].messageLength = 1024B

*.node*.app[0].sendInterval = 1s

# Router Configuration

*.router.numApps = 1

*.router.app[0].typename = “UdpSink”

*.router.app[0].localPort = 5000

# UDP Configuration

*.node*.hasUdp = true

*.router.hasUdp = true

# IP Address Configuration

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

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

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

6. Create IP Address Configuration Files

To build the IP address configuration for every node to make Create XML files.

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

<config>

<interface>

<name>eth0</name>

<address>192.168.1.1</address>

<netmask>255.255.255.0</netmask>

</interface>

</config>

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

<config>

<interface>

<name>eth0</name>

<address>192.168.1.2</address>

<netmask>255.255.255.0</netmask>

</interface>

</config>

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

<config>

<interface>

<name>eth0</name>

<address>192.168.1.254</address>

<netmask>255.255.255.0</netmask>

</interface>

</config>

7. Implement Energy-Aware Component

To implement the energy-aware components and protocols for simulate the green network. Like to build the modules that simulate energy consumption and put into the action in energy-saving techniques.

Example: Energy-Aware Node (Pseudo-Code)

class EnergyAwareNode : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

virtual void finish() override;

private:

double energyConsumed;

void saveEnergy();

};

void EnergyAwareNode::initialize() {

// Initialization code

energyConsumed = 0;

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

}

void EnergyAwareNode::handleMessage(cMessage *msg) {

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

saveEnergy();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

}

void EnergyAwareNode::saveEnergy() {

// Logic to save energy

energyConsumed += 0.1; // Example energy consumption

}

void EnergyAwareNode::finish() {

// Record energy consumption

recordScalar(“EnergyConsumed”, energyConsumed);

}

8. Configure Energy Parameters

To fix the parameters related to savings and energy consumption in the configuration file.

Example: Configuration File with Energy Parameters (omnetpp.ini)

[General]

network = greennetworking.GreenNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.node*.numApps = 1

*.node*.app[0].typename = “UdpBasicApp”

*.node*.app[0].destAddresses = “router”

*.node*.app[0].destPort = 5000

*.node*.app[0].messageLength = 1024B

*.node*.app[0].sendInterval = 1s

# Router Configuration

*.router.numApps = 1

*.router.app[0].typename = “UdpSink”

*.router.app[0].localPort = 5000

# UDP Configuration

*.node*.hasUdp = true

*.router.hasUdp = true

# Energy Parameters

*.node*.energyConsumption = 0.1  # Energy consumed per packet (in arbitrary units)

*.node*.energySavingMode = true  # Enable energy saving mode

# IP Address Configuration

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

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

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

9. Run the Simulation

1. Build the Project: Right-click on the project and choose the Build Project.
2. Run the Simulation: To start the simulations and put on the green play button in the OMNeT++ IDE..
