Reliable gossiping in inter-vehicle communication
Miklós Máté, Rolland Vida
Due to the increasing traffic density in urban areas, a computer-aided robust collision avoidance and traffic control system should be established, based on decentralized inter-vehicle communication. Vehicles group themselves into a special ad hoc network with high mobility and low link reliability. Traditional ad hoc routing solutions cannot cope with these conditions, while flooding based approaches consume too many resources. Our proposed scheme, Localized Urban Dissemination (LUD), is a location aided gossiping protocol, which concentrates the information spreading to areas where it is most likely to be useful. The reliability of simple gossiping, however, is not enough for emergency message dissemination, but our simulations prove that a simple modification in the packet forwarding scheme can overcome this limitation.
