Vehicle to Vehicle Communication using RFID along with GPS and WAP?

This paper studies the vehicle to vehicle communication to share safety messages The communication is one-to-many, local, and geo-significant. The vehicular communication network is ad-hoc, highly mobile, and with large numbers of contending nodes. We design several random access protocols for medium access control. The protocols fit in the facility of RFID, GPS and WAP. This can be done using DSRC.
