How to detect hidden terminal from collision packet

I am using omnet++-5.4.1, veins-4.7.1 and sumo-0.25.0 to simulate vehicle frame transmission. I'd like to determine if the collision frame is from a hidden terminal.



In order to judge whether it is a hidden terminal it is necessary to have the coordinates of the vehicles that sent the collision frame. However, I believe that it is not possible to obtain information on vehicles that sent from collision frames in Decider80211p.



Is there a good way to determine if a conflicting frame is caused by a hidden terminal?



Thank you

  • OMNeT++ simulations are C++ programs. Everything you need is accessible by writing additional C++ code. If you need help with a particular piece of code, just post your question here.

  • Thank you, I currently think of ways to examine hidden terminals in other ways, so there was no need to change Decider80211p.
