VANET Simulation using SUMO

I am trying to use SUMO in my MATLAB VANET simulator, and as per my understanding, SUMO is a standalone mobility simulator which can simulate different mobility models such as: car following (platoon), lane changing and traffic intersections. On the other side, the VANETs applications shall make use of the VANETs protocol messages (Beacon messages or EMG or whatever) and take actions based on these infos and update the vehicles' mobility as well.

I am already familiar with veins and plexe frameworks which already make use of SUMO via TraCI, however I can't understand the big picture for how they affect mobility in SUMO! For instance, in Plexe framework, sumo configuration files with vehicle routings can be loaded in SUMO and simulate the platoon scenario itself, so what is the value added from using VANETs protocol messages? The same for lane changing simulation, SUMO will perform lane change for vehicles based on certain conditions, so what have the VANET simulator to add using the VANETs protocol messages?

Cooperative Adaptive Cruise Control (CACC) requires information about what the preceding vehicle plans to do (as opposed to simply observing what the preceding vehicle is doing). This is only possible if the preceding vehicle communicates its plans wirelessly. Plexe makes it possible to simulate the fact that this wireless exchange of information...

  • takes some time and causes some load on the channel which, in turn, depends on the amount of information exchanged by other vehicles
  • can lose information if...
    • vehicles are too far away
    • vehicles are (partially) hidden behind obstacles
    • vehicles receive multiple transmissions simultaneously
  • (any many more effects)

All of this is simulated by a wireless network simulation made possible by the simulation models of Plexe and Veins running in OMNeT++.
