HOW TO IMPORT CSTATISTIC.H PACKAGES IN OMNET++

The cStatistic Header serves as a crucial element for the collection and management of statistical data during simulations. It establishes a structure for documenting and analyzing various metrics, including throughput, delay, and packet loss, which are vital for assessing the performance and behavior of network models. cStatistic is utilized to monitor quantitative data throughout the simulation, facilitating a variety of statistical functions such as calculating averages, variances, and percentiles. It is capable of processing different data types, including scalar values and histograms, and offers methods for updating, querying, and resetting statistics. This class is frequently employed alongside other OMNeT++ components to gather data from simulation modules and channels. By integrating cStatistic, developers can derive insights from their simulation outcomes, visualize performance metrics, and make informed decisions regarding network design or behavior..

2.OMNeT++ Building Process:

Next, we need to build the Aloha folder to make Aloha Example to work in the OMNET++ 6.0.2 IDE. Right Click the Aloha folder and Click the Build Project Option to build the Aloha Folder.

Here We successfully built and imported the Aloha Example in the OMNET++ IDE.

3.Importing cStatistic.h:

Here we imported the cStatistic.h header file in this example program by clicking the Host.cc, you can see the header imported. So here we need to add code for cStatistic header in the existing code of Aloha Example.

Code for Host.h:

private:

    cOutVector pkCounterVector;  // Vector for storing the number of packets transmitted

    cOutVector txDurationVector; // Vector for storing the duration of each transmission

Code for Host.cc:

#include <algorithm>

#include “Host.h”

#include “omnetpp/cstatistic.h”

namespace aloha {

Define_Module(Host);

Host::~Host()

{

    delete lastPacket;

    cancelAndDelete(endTxEvent);

}

void Host::initialize()

{

    stateSignal = registerSignal(“state”);

    server = getModuleByPath(“server”);

    txRate = par(“txRate”);

    iaTime = &par(“iaTime”);

    pkLenBits = &par(“pkLenBits”);

    slotTime = par(“slotTime”);

    isSlotted = slotTime > 0;

    WATCH(slotTime);

    WATCH(isSlotted);

    endTxEvent = new cMessage(“send/endTx”);

    state = IDLE;

    emit(stateSignal, state);

    pkCounter = 0;

    WATCH((int&)state);

    WATCH(pkCounter);

    x = par(“x”).doubleValue();

    y = par(“y”).doubleValue();

    double serverX = server->par(“x”).doubleValue();

    double serverY = server->par(“y”).doubleValue();

    idleAnimationSpeed = par(“idleAnimationSpeed”);

    transmissionEdgeAnimationSpeed = par(“transmissionEdgeAnimationSpeed”);

    midtransmissionAnimationSpeed = par(“midTransmissionAnimationSpeed”);

    double dist = std::sqrt((x-serverX) * (x-serverX) + (y-serverY) * (y-serverY));

    radioDelay = dist / propagationSpeed;

    getDisplayString().setTagArg(“p”, 0, x);

    getDisplayString().setTagArg(“p”, 1, y);

    scheduleAt(getNextTransmissionTime(), endTxEvent);

    pkCounterVector.setName(“packetCounter”);

    txDurationVector.setName(“transmissionDuration”);

}

 

void Host::handleMessage(cMessage *msg)

{

    ASSERT(msg == endTxEvent);

    getParentModule()->getCanvas()->setAnimationSpeed(transmissionEdgeAnimationSpeed, this);

    if (state == IDLE) {

        char pkname[40];

        sprintf(pkname, “pk-%d-#%d”, getId(), pkCounter++);

        EV << “generating packet ” << pkname << endl;

        state = TRANSMIT;

        emit(stateSignal, state);

        cPacket *pk = new cPacket(pkname);

        pk->setBitLength(pkLenBits->intValue());

        simtime_t duration = pk->getBitLength() / txRate;

        sendDirect(pk, radioDelay, duration, server->gate(“in”));

        scheduleAt(simTime()+duration, endTxEvent);

        pkCounterVector.record(pkCounter);

        txDurationVector.record(duration.dbl());

        if (transmissionRing != nullptr) {

            delete lastPacket;

            lastPacket = pk->dup();

        }

    }

    else if (state == TRANSMIT) {

        state = IDLE;

        emit(stateSignal, state);

        scheduleAt(getNextTransmissionTime(), endTxEvent);

    }

    else {

        throw cRuntimeError(“invalid state”);

    }

}

simtime_t Host::getNextTransmissionTime()

{

    simtime_t t = simTime() + iaTime->doubleValue();

    if (!isSlotted)

        return t;
