Reliable Gossiping in Urban Environments

Abstract

The increased traffic density in urban areas should be handled by a robust collision avoidance and traffic control system that is based on decentralized inter-vehicle communication. In such a special ad hoc network traditional routing protocols cannot cope with the high mobility and low link reliability, while flooding based approaches consume too many resources. Our proposed solution, Carefully Localized Urban Dissemination (CLoUD) is a location-aided gossiping protocol, which concentrates information spreading to areas where it is most likely to be useful. To assess the efficiency of our protocol, we provide a theoretical analysis and show some simulation results.
