In a recent work, the authors proposed LTE4V2X, a novel framework for a centralized vehicular network organization based on 4G LTE network. They demonstrated the efficiency of their framework for an FCD (Floating Car Data) application. Such applications are based on data collected from vehicles (localization, speed, direction, etc.) in order to feed a traffic management server. In the continuity of this paper, this new paper presents two extensions of LTE4V2X. The first one is the multi-hop extension, which uses multi-hop communications to deal with areas where there is no LTE coverage (e.g. tunnels).
