Plenty of multimedia contents such as traffic images, music, and movies pose great challenges for content downloading due to\nthe high mobility of vehicles and intermittent connectivity for vehicular ad hoc networks. Roadside units or APs can improve\nthe efficiency of content downloading but with the cost of large investments. In this paper, an efficient content downloading\nscheme is proposed with the assistance of parking clusters, which are formed by roadside parked cars. After receiving the\ndownloading request, the parking clusters, which the downloader will travel through according to the estimated trajectory, will\nmake a download scheduling for the downloader. Then the downloader acquires the content chunks while it drives through the\nparking clusters. Simulation results show that the proposed scheme achieves better performance than intervehicle approach and\nRSU based approach.
