[ns] VANET in NS-3

Hi everyone,

I'm working on VANET, and want to simulate it in NS-3. but I am not able to
get that is already implemented in NS-3 for VANET environment and what is
needed to implement, for e.g, IEEE 802.11p is required for VANET which is
not implemented as I know.

Please let me know that what is provided and what is needed to implement
for realistic VANET environment in NS-3, so that I can implement the
required protocols, modules etc.

Thanx
