摘      要：Using new wireless capabilities in vehicles, various applications have appeared in Vehicular Ad Hoc Networks (VANETs). Multimedia data sharing is one of these applications, which has recently been given so much attention. Most of presented schemes in this field have focused on direct opportunistic meetings between vehicles or request/response broadcast in the whole network, which are inefficient and un-scalable due to VANET characteristics. In this paper, we propose an ID-based Scalable and EFficient distributed File sharing technique that increases efficiency and scalability via taking advantages of BitTorrent protocol and consistent hashing technique. The results of simulations show that our approach increases the received file ratio, reduces total download time of files and message overhead. Consequently, it can enhance efficiency and performance.
