Abstract: Efficient content distribution in Vehicular Ad hoc Networks (VANETs) has been a critical challenge due to the VANETs highly dynamic topology. The Vehicular Named-Data Networking (VNDN) architecture has been proposed to deal with performance and reliability challenges in high-scale content delivery. Content-centric communication and in-network caching are characteristics of Named Data Networking (NDN) architecture and have great potential to improve content delivery in applications for VANETs. However, the integration of NDN architecture into VANETs generates uncontrolled Interest packet transmissions in the cache discovery process, which results in a waste of resources and diminishes the performance of the network. In this work, we propose the Content Discovery Protocol (CDP) to mitigate the broadcast storm problem in the VNDN cache discovery. When compared with other solutions in the literature, CDP protocol improves the content delivery rate by 66%, reduces the number of Interest transmissions in the cache discovery process by 82%, and decreasing the number of collisions by 68%.
