Content-centric vehicular networking: An evaluation study

Content-centric networking (CCN) is a promising paradigm for the future Internet architecture. Data access and delivery in a content-centric network rely on content names instead of host addresses. Some preliminary results have shown that a CCN-like approach outperforms the legacy TCP/IP protocol suite and well copes with dynamic, short-lived and intermittent connectivity in vehicular environments. To assess and extend our previous findings, in this paper we report the results of a broad simulation study aiming at evaluating the effectiveness and efficiency of the proposed content-centric vehicular networking architecture under a variety of different traffic loads, vehicle densities, and content popularity settings.
