Abstract Newer mobile devices are equipped with multiple network interfaces that can be used to pre-emptively download multimedia content in an efficient and cost effective manner. We propose a content selection algorithm for such push-based multimedia content caching scenarios. Our approach improves cache hit rates by exploiting correlations between users who request similar content: we use this information to select cache content intelligently. Using real data collected from an Internet movie ratings web-site, we experimentally verify the superiority of our approach over the widely used technique of pushing the most popular content onto all mobile devices. We also propose a distributed version of our approach that is suitable for ad hoc mobile device networks.
