Wireless sensor networks OMNET ++ study notes and (iii) simple module

Four main functions:

1.  the initialize (); (initialize variables, initialization scheduled events, such as call 2) is not a constructor
2.  handleMessage(cMessage *msg);
   • send () sends a message to other modules
   • scheduleAt () message to yourself
   • cancelEvent () deletes a scheduleAt () event scheduled
3. activity();
4.  finish (); simulation end recording statistics. Not analyzer configuration.

.h file

class Txc : public cSimpleModule
{
  protected:
    virtual void initialize();
    virtual void handleMessage(cMessage *msg);
    virtual void finish();
