One of the best platforms for modelling and simulating V2V communication network is the matalb/simulink. There is matlab tools for communications processing and signal processing. You can exploit them to model and simulate your own network structure.
One of the best platforms for modeling and simulating a V2V communication network is Matlab/Simulink. There are Matlab tools for communications processing and signal processing.
as others said, Matlab/Simulink is an effective choice, while imho they are more targeted at low level emi simulations, or to crowd simulations.
If you would like to find a very effective simulation program, with lots of protocols already included, a very good GUI for programming and suitable to V2V scenarios, I would suggest Omnet++.
