OMNET++ Transmit message via Ethernet or Wireless

Question

i am new in using the OMNET++ simulator. Currently i want to build a network which consists of two or more nodes, each having two interfaces on which they can send messages out (e.g. Ethernet and Wireless).

I want to program the node behavior by myself. When a message arrives at a host, i want to define in the handleMessage(cMessage *msg) method, whether the host should transmit the received message via Ethernet or Wireless interface.

Can i take the WirelessHost from the INET package for this scenario? If yes, how can i program the decision on what interface to use for retransmitting the received message? I followed the wireless tutorial from INET, but they only configure .ned and .ini files but not the .cc files where the behavior is coded.

In the tutorial the UdpBasicApp was used. It would be nice if i could write an own App like described above.

Thanks in advance!

Right. You can tune your own node, just creating a new one (.h .ned .cc file), that can import and reuse Wireless host features and add/override extra functions. So a custom MyNode.cc file for new MyNode element could be:

#include "MyNode.h"
#include <string.h>
#include <omnetpp.h>

void MyNode::initialize()
{
}

void MyNode::handleMessage(cMessage *msg)
{
 EV << "Received message, now applying new custom procedure \n";
 new_behaviour msg;
}

Also can help you here a complete sample of a new node created to delete all received packets OMNET++ How to retain all functions in AODVRouting class but override sendAODVPacket function only?
