Creating of messages is described in OMNeT++ Simulation Manual as well as in TicToc Tutorial.
In short:

  1. You have to create a new .msg file, for example ControlMessage.msg, with your content, for example:

    message ControlMessage {
  int someAddress;
  // ...
}

  2. In your C++ code you have to add the following line:

    #include "ControlMessage_m.h"

(during compilation ControlMessage_m.h is automatically created from ControlMessage.msg)

After creating the three message classes, in a class, say DemoLayer, you need 2 changes in .h file and 1 in .cc file.

In .h file, under the public specifier add

enum DemoMessageKinds {
    SEND_DATA-MESSAGE,
    SEND_CONTROL-MESSAGE,
    SEND_JOB-MESSAGE
};

and under protected specifier add

void handleSelfMsg(cMessage* msg) override;

In .cc file, add

void DemoLayer::handleSelfMsg(cMessage* msg)
{   
   switch (msg->getKind()) 
   {
      case SEND_DATA-MESSAGE: 
      {
        ControlMessage* cm = new ControlMessage();
        ....//

For an example, check this https://github.com/sommer/veins/tree/master/src/veins/modules/application/ieee80211p

  • Hi. If you found my answer working, please mark it as answered. – Pasha M. Mar 06 '22 at 09:08
  • hi sure dear, but i want to define these types for all module, I mean in this way do I have a personal message just for a especial module? – Fatimah Faraji Mar 06 '22 at 10:12
  • Yes. You are right. handleSelfMessage () is used to handle messages within the module. Please use handleMessage( ) if you want all modules to get the generated message(s). – Pasha M. Mar 06 '22 at 13:02
  • I used the method name as handleMessage( ) referring to the tic-toc example. – Pasha M. Mar 06 '22 at 13:27
