Recently, many researchers focus on delay tolerant networks (DTN). In DTN, the mobile characteristic of nodes is used to help transfer data. Therefore, how to use the cooperative relations and cache resource of nodes effectively to avoid network congestion and improve network performance is an important issue. In this paper, we proposed a cooperative caching policy based on human mobile patterns, which referred as HMP-Cache. The node movement characteristics are discussed in detail in HMP-Cache. HMP-Cache uses the standard of target address matching to choose cooperative caching nodes. In addition, the sharing caching information is done by synchronization of caching table in local region. Therefore, the impact of useless data dissemination of multiple hops is reduced. And the shortcoming of limited caching resources is compensated. The simulation results show that our policy can control the network cost effectively. Also, the remote data latency is reduced.
