Abstract
Vehicular ad hoc networks (VANETs), which can provide drivers with convenience and entertainment services, have attracted attentions from both academia and industry. In the VANETs, caching contents at the edge of road-side units (RSUs) can facilitate the timely content delivery to driving-through vehicles when requested. However, as both the scale of network and the number of content keep increasing, due to the limited cache capacity, how to selectively keep the replicas in the cache in VANETs becomes a challenging issue. In this paper, to resolve the above issue, we firstly make an analysis on the edge caching based on content access, vehicle velocity and road traffic. Then, we propose a cost model to decide whether and where to obtain the caching replica of content when the moving vehicle requests for it. In addition, we prove the efficiency of our proposed scheme with intensive simulation experiments.
