摘要

提出了一种新的内容缓存策略，用于支持缓存的设备到设备(D2D)网络，其中允许用户设备使用毫米波(mmWave) D2D链路(bbb6ghz)以及传统的sub - 6GHz蜂窝链路进行通信。所提出的内容放置策略最大化了视线D2D链接的成功内容传递概率。在此基础上，提出了一种有效的启发式内容传递算法。与传统的缓存命中最大化内容放置和交付策略相比，总体方案提高了网络的成功流量卸载增益。在超密集网络中也可以实现显著的能源效率改进。

A Novel Content Caching and Delivery Scheme for Millimeter Wave Device-to-Device Communications

A novel content caching strategy is proposed for a cache enabled device-to-device (D2D) network where the user devices are allowed to communicate using millimeter wave (mmWave) D2D links (> 6GHz) as well as conventional sub 6 GHz cellular links. The proposed content placement strategy maximizes the successful content delivery probability of a line of sight D2D link. Furthermore, a heuristic algorithm is proposed for efficient content delivery. The overall scheme improves the successful traffic offloading gain of the network compared to conventional cache-hit maximizing content placement and delivery strategies. Significant energy efficiency improvements can also be achieved in ultra-dense networks.
