A Framework for Efficient Interest-Packet Dissemination in Content-Centric Vehicular Networks

This paper proposes the GeoZone framework in order to reduce the broadcast storm of interest packets in content-centric vehicular networks. The proposed framework is composed of (i) a geo-referenced naming scheme, which is also transparent for vehicular applications, and (ii) an interest-packet forwarding mechanism that defines a dissemination zone to reduce network flooding. Simulations are performed in different scenarios to compare the efficiency of our framework with other proposals. Compared to these proposals, the GeoZone framework reduces up to 66 % the number of interest packets transmitted without sacrifice to the content-delivery rate and delay.
