Omnet++ and MiXiM

Question

I am trying to run simulations for 802.15.4a devices. For this reason I am using MiXiM which provides very useful modules.

More specifically I want to have a first (very easy) configuration where two Host802154A communicate with each other.

I then created a network.ned as follows

package eval;
import inet.physicallayer.ieee802154.bitlevel.Ieee802154UWBIRRadioMedium;
import org.mixim.modules.node.Host802154A;


//
// TODO documentation
//
network env
{
    @display("bgb=639,446");
    submodules:
        dev1: Host802154A {
            @display("p=128,166");
        }
        dev2: Host802154A {
            @display("p=402,166");
        }
        ieee802154Medium: Ieee802154UWBIRRadioMedium {
            @display("p=513,37");
        }
}

I checked many guides to run experiments but I am not sure I understood how to 'start'.

I need an omnetpp.ini file but what should it contain?

Do I have to define two .cc files for dev1 and dev2?

I just want to have the two devices exchanging messages, nothing more than that.

Indeed, you are going to need an omnetpp.ini file. Check the OMNeT++ manual and the most important tutorial - the TicToc Tutorial

A (bit outdated) quick-start guide is available here: https://omnetpp.org/pmwiki/index.php?n=Main.OmnetppInNutshell

As for additional .cc files, if you rely on standard host definitions from MiXiM, you wont need any additional .cc files. The basic MiXiM examples provide more insight on how MiXiM hosts and classes are instantiated and used, while the omnetpp.ini will provide the correct parametrization.
