Optimal Network Selection Method Using Federated Learning for Achieving Both Privacy Preservation and Large-Scale Learning
Koki Horita (Sony), Akihiro Nakao (UTokyo) NS2022-13
Abstract (in Japanese) (See Japanese page) 
(in English) A smartphone switches from a wireless LAN to a mobile network, including 5G, due to changes in the communication environment. Although it is useful to employ machine learning to learn a model to predict the wireless environment from
a large amount of data, it is difficult to utilize data obtained from the market devices because they contain the personal information of users. In this paper, we introduce Federated Learning for learning network selection models. The model enables large-scale
learning using market data with user privacy protected and developing a model to predict the quality of the network. We evaluate the performance of these models for optimal network switching by installing them on Android devices. Our proposed method
shows that it is effective in improving user experiences by up to 400% by reducing network switching based on advance prediction.
