Abstract

In F-RANs, content caches are deployed at both the cloud and fog computing layers to keep the popular content objects at the edge of networks. Therefore, a part of user requests can be responded immediately without multi-hop routing, and the QoS guarantee can be improved significantly. In this chapter, we will firstly introduce the hierarchical cooperative caching framework in F-RANs. Next, the content delivery schemes in F-RANs will be introduced, where the content pushing procedure will be considered as well. Finally, the joint optimization of caching and radio resources will be studied to improve the utility and reduce the cost of content caching.
