Yes, it is possible to simulate a VANET-based collision avoidance system in NetSim (https://tetcos.com/vanets.html). I have worked on modeling V2V communication where safety messages are exchanged between vehicles to avoid collisions. NetSim supports visualization of vehicle movement and message flows, which helps in analyzing how effective the avoidance strategies are.

For vehicle mobility, NetSim integrates with SUMO. By default, SUMO has built-in collision avoidance, but you can tweak it to simulate collisions under specific conditions. These links helped me understand that part:

• https://sumo.dlr.de/docs/Simulation/Safety.html#collisions
• https://support.tetcos.com/support/solutions/articles/14000107994-how-to-simulate-an-accident-in-netsim-vanet-
• https://sumo.dlr.de/docs/FAQ.html#how_to_simulate_an_accident

In my case, I used safety message broadcasts along with TraCI APIs to detect potential collisions. NetSim lets you trigger rerouting or take other actions based on those detections. This example was useful for me:

You can adapt that same logic for pure V2V-based collision avoidance.

Hello Sujata, it is possible, I found the following discussions could be useful

Good Luck!
