Multimedia Content Downloading In VANET with Density Estimation

The existence of Internet-connected navigation and infotainment systems is becoming a truth that will easily lead to a remarkable growth in bandwidth demand by in-vehicle users. This content downloading system will induce the vehicular user to use the resource to the same extent as today’s mobile customers. By this approach communication-enabled vehicles are paying attention in downloading different contents from Internet-based servers. We summarize the performance limits of such a vehicular multimedia content downloading system by modeling the content downloading process as an optimization problem, and maximizing the overall system throughput with density measurement. Results highlight the methods where the Roadside infrastructure i.e., access points are working at different capabilities irrespective of vehicle density, the vehicle-to-vehicle relaying, and the penetration rate of the vehicular communication.
