Detailed Description

In this step we'll introduce random numbers. We change the delay from 1s to a random value which can be set from the NED file or from omnetpp.ini. In addition, we'll "lose" (delete) the packet with a small probability.

void Txc7::handleMessage

(

cMessage *

msg

)

[protected, virtual]

Reimplemented from cSimpleModule.

{
    if (msg==event)
    {
        EV << "Wait period is over, sending back message\n";
        send(tictocMsg, "out");
        tictocMsg = NULL;
    }
    else
    {
        // "Lose" the message with 0.1 probability:
        if (uniform(0,1) < 0.1)
        {
            EV << "\"Losing\" message\n";
            delete msg;
        }
        else
        {
            // The "delayTime" module parameter can be set to values like
            // "exponential(5)" (tictoc7.ned, omnetpp.ini), and then here
            // we'll get a different delay every time.
            simtime_t delay = par("delayTime");

            EV << "Message arrived, starting to wait " << delay << " secs...\n";

            scheduleAt(simTime()+delay, event);
        }

void Txc7::initialize

[protected, virtual]

Reimplemented from cComponent.

    if (strcmp("tic", getName()) == 0)
    {
        EV << "Scheduling first send to t=5.0s\n";
        scheduleAt(5.0, event);
        tictocMsg = new cMessage("tictocMsg");
    }
