Nowadays, to deal with driving safety-related issues and improve travel comfort, the VehiculAr NETwork (VANET) has gained tremendous attention from researchers in both academia and industry around the world. By taking advantage of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, the VANET can significantly enhance road safety and travel comfort by improving drivers' awareness of their surrounding road environment and providing entertainment-related data service for passengers, respectively. However, due to the highly dynamic nature of the network topology in VANET, how to achieve reliable data transmission and content delivery is a critical task for implementing VANETs. Accordingly, in this article, we provide a novel data-highway-assisted content delivery protocol for addressing the content delivery problem in VANETs, in which, we explore the advantages of the predicted …
