Fuzzy Logic Based Client Selection for Federated Learning in Vehicular Networks

Federated learning is a promising paradigm for achieving distributed intelligence by protecting user privacy in vehicular networks. Considering limited computing and communication resources, it is important to select appropriate clients from a huge number of users to participate in the training process. In vehicular networks, the problem of choosing proper clients is particularly complex due to the heterogeneity of network users, including the differences in the data, computation capability, available throughput, and samples freshness. We design a fuzzy logic based client selection scheme to address this issue. The proposed scheme considers the number of local samples, samples freshness, computation capability, and available network throughput based on a fuzzy logic approach. Extensive simulation results show that the proposed scheme outperforms other baselines.
