I am new to omnet++ and veins, I want to simulate a simple scenario where an RSU sends a message to every node that enters its transmission range.
I know that I have to modify the TraCIDemoRSU11p.cc class to achieve this. But even though I searched the veins frame work documentation, I can't figure out what function will allow me to know when a vehicle enters the RSU transmission range, so I can send the message.
How could I go about this?
