Txc10 Class Reference

List of all members.

Detailed Description

In this step the destination address is no longer node 2 -- we draw a random destination, and we'll add the destination address to the message.

The best way is to subclass cMessage and add destination as a data member. Hand-coding the message class is usually tiresome because it contains a lot of boilerplate code, so we let OMNeT++ generate the class for us. The message class specification is in tictoc10.msg -- tictoc10_m.h and .cc will be generated from this file automatically.

To make the model execute longer, after a message arrives to its destination the destination node will generate another message with a random destination address, and so forth.

void Txc10::forwardMessage (  TicTocMsg10 *  msg  )  [private, virtual]

{ // Increment hop count. msg->setHopCount(msg->getHopCount()+1); // Same routing as before: random gate. int n = gate("out")->size(); int k = intuniform(0,n-1); ev << "Forwarding message " << msg << " on port out[" << k << "]\n"; send(msg, "out", k); }

TicTocMsg10 * Txc10::generateMessage (   )  [private, virtual]

{ // Produce source and destination addresses. int src = index(); // our module index int n = size(); // module vector size int dest = intuniform(0,n-2); if (dest>=src) dest++; char msgname[20]; sprintf(msgname, "tic-%d-to-%d", src, dest); // Create message object and set source and destination field. TicTocMsg10 *msg = new TicTocMsg10(msgname); msg->setSource(src); msg->setDestination(dest); return msg; }

void Txc10::handleMessage (  cMessage *  msg  )  [private, virtual]

Reimplemented from cSimpleModule. { TicTocMsg10 *ttmsg = check_and_cast<TicTocMsg10 *>(msg); if (ttmsg->getDestination()==index()) { // Message arrived. ev << "Message " << ttmsg << " arrived after " << ttmsg->getHopCount() << " hops.\n"; bubble("ARRIVED, starting new one!"); delete ttmsg; // Generate another one. ev << "Generating another message: "; TicTocMsg10 *newmsg = generateMessage(); ev << newmsg << endl; forwardMessage(newmsg); } else { // We need to forward the message. forwardMessage(ttmsg); } }

void Txc10::initialize (   )  [private, virtual]

Reimplemented from cModule. { // Module 0 sends the first message if (index()==0) { // Boot the process scheduling the initial message as a self-message. TicTocMsg10 *msg = generateMessage(); scheduleAt(0.0, msg); } }
