摘要In order to solve the problem of the limited storage capacity of server in mobile edge computing (MEC), a MEC-D2D collaborative content cache placement strategy based on dynamic programming was proposed by taking advantage of the data-sharing advantages of device-to-device (D2D) communication technology. Firstly, the influence of content popularity, cache space finiteness and interference limitation on the average delay of user content acquisition were analyzed. Secondly, by establishing a segmented content acquisition model, the optimization goal was to reduce the average delay of user content acquisition. Finally, the cache problem was considered as a complete knapsack problem, and the optimal cache allocation scheme was designed by the dynamic programming algorithm. Simulation experiment results show that the proposed caching strategy can reduce the average latency of user content acquisition effectively. © 2021, Editorial Board of Journal of Huazhong University of Science and Technology.
