Vehicular Ad-Hoc Network (VANET) applications usually require some kind of content to be delivered to vehicles. However, this task is easier said than done because of the VANET's specific characteristics, such as highly dynamic topology, short intermittent contacts, different density scenarios, and large-scale, to name a few. Thus, one concept that seems to be of great help is that of Content Delivery Network (CDN), in which strategically nodes are selected to act as servers and to help on the delivery process. Some researchers have started working on the application of such concept to VANET scenarios. In this paper, we present the state-of-the-art survey on the vehicular content delivery network (VCDN) field by presenting and discussing the main related studies found in the literature.
