In real environments, these training nodes are heterogeneous in computing capacity and bandwidth, thus their specific characteristics influence the performance of the federated learning process. We propose for such situations the design of a federated learning server that is able to adapt dynamically to the heterogeneity of the training nodes. In experiments with real devices deployed in a wireless mesh network, we observed that the designed adaptive federated learning server successfully exploited the idle times of the fast nodes by assigning them larger training workloads, which led to a higher global model performance without increasing the training time.}, year = {2023}, month = {08/2023}, publisher = {Springer International Publishing}, address = {Cusco, Peru}, isbn = {978-3-031-33261-6}, url = {https://doi.org/10.1007/978-3-031-33261-6_25}, }
