使用Omnet++从同一源节点生成perodic消息

omnet++ c++

void Txc13::initialize()
{
    // Module 0 sends the first message
    if (getIndex() == 0) {
        // Boot the process scheduling the initial message as a self-message.
        TicTocMsg13 *msg = generateMessage();
        simtime_t delay = par("delayTime");
        scheduleAt(simTime()+delay, msg);
    }
}

void Txc13::handleMessage(cMessage *msg)
{
    // we do some casting to access the fields inside the message
    TicTocMsg13 *ttmsg = check_and_cast<TicTocMsg13 *>(msg);

    if (ttmsg->getDestination() == getIndex()) {
        // Message arrived.
        bubble("ARRIVED!");
        delete ttmsg;
    }
    else {
        // We need to forward the message.
        forwardMessage(ttmsg);
    }
}

getIndex()==0 )到达预定目的地。

现在我愿意触发几条留言 node0 过了一会儿 delay

延迟呈指数分布 network.tic[*].delayTime = exponential(10s) .

如何从同一节点触发多条消息?

谢谢!

好的,我想我明白了。这是两种方法的代码。在 initialize event 我最初触发的消息 t=0 .

void Txc13::initialize()
{
    // Create the event object we'll use for timing -- just any ordinary message.
    event = new cMessage("event");
    // Module 0 sends the first message
    if (getIndex() == 0) {
        scheduleAt(0.0, event);
    }
}

handleMessage 方法I检查传入的消息是否为 事件 simtime_t delay = par("delayTime")

getIndex() == 0 .

void Txc13::handleMessage(cMessage *msg)
{
    if (msg == event and getIndex() == 0){
        TicTocMsg13 *msg = generateMessage();
        simtime_t delay = par("delayTime");
        scheduleAt(simTime()+delay, event);
        forwardMessage(msg);
    }
    else {
        // we do some casting to access the fields inside the message
        TicTocMsg13 *ttmsg = check_and_cast<TicTocMsg13 *>(msg);

        if (ttmsg->getDestination() == getIndex()) {
            // Message arrived.
            //EV << "Message " << ttmsg << " arrived after " << ttmsg->getHopCount() << " hops.\n";
            bubble("ARRIVED!");
            delete ttmsg;

            // Generate another one.
            //EV << "Generating another message: ";
            //TicTocMsg13 *newmsg = generateMessage();
            //EV << newmsg << endl;
            //forwardMessage(newmsg);
        }
        else {
            // We need to forward the message.
            forwardMessage(ttmsg);
        }
    }
}
