%X In order to solve the problem of efficient deployment caching in mobile networks, a content caching mechanism based on bipartite graph was proposed. When selecting the content caching nodes, it is necessary to consider not only the content's interest degree in each node, but also the link states between nodes. Based on this scheme, those nodes which are most interested in the content and have the best network status will be selected to pre-cache the content, thereby improving the content distribution efficiency and reducing the content transmission delay. Simulation results are illustrated to show that the proposed scheme can improve the utilization efficiency of cache space, reduce the content transmission delay and enhance users' experience.
