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 tictoc13.msg -- tictoc13_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 Txc13::initialize (  )  [protected, virtual]

Reimplemented from cComponent.
