Detailed Description

This model is exciting enough so that we can collect some statistics. We'll record in output vectors the hop count of every message upon arrival. Output vectors are written into the omnetpp.vec file and can be visualized with the Plove program.

We also collect basic statistics (min, max, mean, std.dev.) and histogram about the hop count which we'll print out at the end of the simulation.

void Txc12::finish (   )  [protected, virtual]

Reimplemented from cModule. { // This function is called by OMNeT++ at the end of the simulation. ev << "Sent: " << numSent << endl; ev << "Received: " << numReceived << endl; ev << "Hop count, min: " << hopCountStats.min() << endl; ev << "Hop count, max: " << hopCountStats.max() << endl; ev << "Hop count, mean: " << hopCountStats.mean() << endl; ev << "Hop count, stddev: " << hopCountStats.stddev() << endl; recordScalar("#sent", numSent); recordScalar("#received", numReceived); hopCountStats.recordScalar("hop count"); }

void Txc12::forwardMessage (  TicTocMsg12 *  msg  )  [protected, 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); }

TicTocMsg12 * Txc12::generateMessage (   )  [protected, virtual]

{ // Produce source and destination addresses. int src = index(); int n = 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. TicTocMsg12 *msg = new TicTocMsg12(msgname); msg->setSource(src); msg->setDestination(dest); return msg; }

void Txc12::handleMessage (  cMessage *  msg  )  [protected, virtual]

Reimplemented from cSimpleModule. { TicTocMsg12 *ttmsg = check_and_cast<TicTocMsg12 *>(msg); if (ttmsg->getDestination()==index()) { // Message arrived int hopcount = ttmsg->getHopCount(); ev << "Message " << ttmsg << " arrived after " << hopcount << " hops.\n"; bubble("ARRIVED, starting new one!"); // update statistics. numReceived++; hopCountVector.record(hopcount); hopCountStats.collect(hopcount); delete ttmsg; // Generate another one. ev << "Generating another message: "; TicTocMsg12 *newmsg = generateMessage(); ev << newmsg << endl; forwardMessage(newmsg); numSent++; } else { // We need to forward the message. forwardMessage(ttmsg); } }

void Txc12::initialize (   )  [protected, virtual]

Reimplemented from cModule. { // Initialize variables numSent = 0; numReceived = 0; WATCH(numSent); WATCH(numReceived); hopCountStats.setName("hopCountStats"); hopCountStats.setRangeAutoUpper(0, 10, 1.5); hopCountVector.setName("HopCount"); // Module 0 sends the first message if (index()==0) { // Boot the process scheduling the initial message as a self-message. TicTocMsg12 *msg = generateMessage(); scheduleAt(0.0, msg); } }
