Abstract

The invention relates to a content caching method based on federated learning in a fog computing network, and belongs to the technical field of mobile communication. By deploying the content cache inthe F-RAN, rapid and repeated data access can be realized, and the network transmission flow is reduced. Due to the limitation of the cache capacity, the prediction of the popularity of the content and the caching of which popular contents are very important. Generally, most classical prediction methods need to collect personal user information in a central unit, and many user privacy problems arecaused. The invention provides an intelligent F-RANs example based on federated learning. Federal learning is applied to a demand prediction problem, and content popularity distribution in a networkcan be accurately predicted. In addition, in consideration of the content request of the user, the problems of storage resource allocation and content placement in the network are jointly optimized. According to the method, the joint optimization problem is expressed as an integer linear programming model, and the purpose is to minimize the total flow cost of the network.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a content caching method based on federated learning in a fog computing network. Background technique [0002] In recent years, the increasing popularity of smart devices such as wearable devices, smartphones, and sensors in our daily life has triggered a surge in many distributed network devices, generating massive heterogeneous data that needs to be processed. Due to the unprecedented and exponential growth of data volume, and the typical private nature of these data, it becomes impractical and fraught with privacy issues to send all data to cloud computing centers for processing. In addition, some applications and services rely heavily on high-speed data rates and low-latency transmission, prompting mobile network operators to rethink current network close to the end user. [0003] Therefore, to meet multiple multi-dimensional requirements for quality of service, ...
