ABSTRACT:
A system and method for allowing vehicle occupants to wirelessly chat with each other over a DSRC channel. A vehicle occupant may initiate a chatting session by wirelessly transmitting a request to speak with an occupant of another vehicle in its vicinity on a certain topic in a multi-hop manner. If the request is accepted by the occupant of another vehicle to enter into a chatting session on that topic, a wireless communications link is established between the two vehicles, where messages may be transmitted through other intermediate vehicles. The chatting session is maintained by monitoring the signal strength of the links between the vehicles in the chain of vehicles and new links are re-established if any of the existing links fail.
