MSN (Mobile Social Network) enables nodes (mobile devices) to realize packet delivery by leveraging social relationships of mobile users. However, MSN has to adapt with the daily increasing content (e.g., video) requirement requested by mobile users. Based on the fact that ICN (Information-Centric Networking) supports mobility naturally, we propose an MSN content-centric routing scheme. It is inspired by the in-network caching and named-content properties of Named Data Networking. By the analysis of the historical requested content names of MSN users, a novel interest distance metric is proposed, based on which, the forwarding node is selected for an interest packet. Meanwhile, by the analysis of the historical encounters of MSN nodes, a novel encounter regularity metric is proposed, based on which, the forwarding node is selected for a data packet. Furthermore, in order to respond the forth-coming requests rapidly, nodes preferentially cache the content which with high requested probability. By comparing with the existed schemes, simulation experiments represent that our scheme is effective and feasible.
