i think the model used for multi-hop MIMO relay networks would be applicable for V2V and V2I simulations. The main differences would be that for V2V communications you have to consider a moving relay or a number of relays and the appropriate channels between them. Similarly for V2I the relays would be considered fixed.

Sir, thanks for your suggestion.

Sir, I also wanted know that in case of V2V and V2I, is there any statistical difference in the distribution of the channel?

See the attached thesis as well

Thanks Sir.
