How to Implement Distributed Computing in OMNeT++

To implement the distributed computing in OMNeT++ encompasses site up a recreation atmosphere where numerous nodes connect and cooperate to achieve computational tasks. Here’s a steps to set up a basic dispersed computing simulation in OMNeT++.

Step-by-Step Implementation:

Step 1: Install OMNeT++ and INET Framework

1. Download OMNeT++:
   • Download the new version and the way to  OMNeT++.  
2. Install OMNeT++:
   • For the operating systems we follow the installation instructions provided on the website.
3. Download and Install INET Framework:
   • For the internet protocols is often by using among the OMNeT++ provided by the INET framework.
   • To download it from the INET website.

Step 2: Set Up Your Project

1. Create a New OMNeT++ Project:
   • Open the OMNeT++ IDE.
   • Go to File -> New -> OMNeT++ Project.
   • Arrive a project name and choice the proper decisions.
2. Set Up Directory Structure:
   • For NED files and arrangement to simulates to src and make sure the project has the essential folders..

Step 3: Define Network Models Using NED

1. Create NED Files:
   • In the src directory, produce a new NED file for e.g., DistributedComputingNetwork.ned.
   • Express the network topology in the NED file. Given below a simple example:

package distributedcomputing;

import inet.node.inet.StandardHost;

import inet.networklayer.configurator.ipv4.Ipv4NetworkConfigurator;

import inet.linklayer.ethernet.EthernetInterface;

import inet.common.misc.ThruputMeteringChannel;

network DistributedComputingNetwork

{

parameters:

int numNodes = default(10);

submodules:

configurator: Ipv4NetworkConfigurator {

@display(“p=100,100”);

}

node[numNodes]: StandardHost {

@display(“p=200+100*i,200”);

numWlanInterfaces = 1;

}

connections allowunconnected:

for i=0..numNodes-1 {

for j=i+1..numNodes-1 {

node[i].ethg++ <–> ThruputMeteringChannel <–> node[j].ethg++;

}

}

}

Step 4: Implement Distributed Computing Logic in C++

1. Create C++ Modules:
   • In the src directory, create a new C++ class such as  DistributedNode.cc.
   • Embrace necessary OMNeT++ headers and outline your module:

#include <omnetpp.h>

#include “inet/applications/udpapp/UdpBasicApp.h”

using namespace omnetpp;

using namespace inet;

class DistributedNode : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

void startTask();

void distributeTask();

void collectResults();

};

Define_Module(DistributedNode);

void DistributedNode::initialize()

{

// Initialization code

scheduleAt(simTime() + par(“startTaskInterval”), new cMessage(“startTask”));

}

void DistributedNode::handleMessage(cMessage *msg)

{

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

startTask();

delete msg;

} else if (strcmp(msg->getName(), “distributeTask”) == 0) {

distributeTask();

delete msg;

} else if (strcmp(msg->getName(), “collectResults”) == 0) {

collectResults();

delete msg;

}

}

void DistributedNode::startTask()

{

// Code to start a distributed task

EV << “Starting a distributed task” << endl;

// Schedule task distribution

scheduleAt(simTime() + par(“distributeTaskInterval”), new cMessage(“distributeTask”));

}

void DistributedNode::distributeTask()

{

// Code to distribute tasks to other nodes

EV << “Distributing tasks to other nodes” << endl;

// Schedule result collection

scheduleAt(simTime() + par(“collectResultsInterval”), new cMessage(“collectResults”));

}

void DistributedNode::collectResults()

{

// Code to collect results from other nodes

EV << “Collecting results from other nodes” << endl;

}

1. Modify NED to Use C++ Modules:
   • Apprise the NED file to use the custom spread node module:

network DistributedComputingNetwork

{

parameters:

int numNodes = default(10);

submodules:

configurator: Ipv4NetworkConfigurator {

@display(“p=100,100”);

}

node[numNodes]: DistributedNode {

@display(“p=200+100*i,200”);

numWlanInterfaces = 1;

}

connections allowunconnected:

for i=0..numNodes-1 {

for j=i+1..numNodes-1 {

node[i].ethg++ <–> ThruputMeteringChannel <–> node[j].ethg++;

}

}

}

Step 5: Configure Simulation Parameters

1. Create omnetpp.ini:
   • In the simulations directory, form an omnetpp.ini file.
   • Explain simulation parameters, like the duration and network parameters:

[General]

network = DistributedComputingNetwork

sim-time-limit = 10s

**.startTaskInterval = 1s

**.distributeTaskInterval = 2s

**.collectResultsInterval = 3s

Step 6: Build and Run the Simulation

1. Build the Project:
   • In the OMNeT++ IDE, right-click on the project and select Build Project.
2. Run the Simulation:
   • Go to Run -> Run Configurations.
   • To make a new run configuration for the project and run the simulation.

Step 7: Analyze Results

1. View Simulation Results:
   • After the simulation completes, custom OMNeT++’s tools to study the outcomes.
   • Exposed the ANF (Analysis Framework) to visualize and read the data.
