Recent vehicular ad hoc network routing protocols have relied on geographic forwarding and careful selection of road segments as ways to reduce the impact of individual vehicle movements. This paper shows how a virtualization layer and a new protocol running on top of it —called VNIBR, intersection-based routing on virtual nodes—can achieve better performance than state-of-the-art approaches, enabling...
Many routing algorithms for vehicular ad-hoc networks have relied on geographic forwarding as a means to reduce the paths' sensitivity to individual vehicle movements. In recent years, the basic forwarding strategies have been refined to create road-based paths, connecting successive road intersections selected on the basis of the connectivity between them. Revisiting this idea, we present three different...
The growth of mobile data traffic is urging on the development of mechanisms to route cellular traffic through alternative networks. In this paper, we present an approach to do mobile data offloading from/to vehicular ad hoc networks (VANETs), grounded on a virtualization layer and a new routing protocol on top of it. The virtualization layer deals with the issues derived from the mobility of the...
