A Reliable Robust Fully Ad Hoc Data Dissemination Mechanism for Vehicular Networks

Free registration required

Executive Summary

Many applications in vehicular networks need the data to be disseminated from a source vehicle to a large number of vehicles in the network. Although many solutions to this problem have been previously proposed by the research community, some challenges and failure scenarios still remain unsolved particularly when the forwarding vehicle is located at an intersection and it wants to disseminate the data to all the intersecting road segments. In this paper, the authors first evaluate some of the previously proposed directional mode (along the straight roads) data dissemination mechanisms and then integrate the one with the best performance with the novel reliable robust intersection mode data dissemination mechanism in order to come up with a united mechanism for disseminating data both along the straight roads and at intersections.
