摘要:

联邦学习(FL)允许设备在不共享数据的情况下训练全局机器学习模型。在无线网络环境中,传输信道固有的不可靠性会引入延迟和错误,从而影响全局模型更新的规律性。此外,设备有限的资源和能量消耗也是影响FL性能的因素。因此,本文提出了一种名为FL-E2WS的新型FL算法,该算法在物联网范围内同时考虑联邦训练需求和无线网络条件。为降低设备的能量成本,FL-E2WS在特定设备选择和上行资源块分配下调度通信资源,为模型传输分配理想的带宽和功率,同时满足延迟要求、功耗限制和误包率约束。仿真结果表明,与缺乏传输信道知识的FL算法相比,FL-E2WS可将能耗降低高达70.12%,并将全局模型的准确率提升高达10.21%。此外,与扩展通信资源的FL版本相比,FL-E2WS实现了高达38.61%的能耗降低,并将全局模型的准确率提升高达1.61%。

英文摘要:

Federated Learning (FL) allows devices to train a global machine learning model without sharing data. In the context of wireless networks, the inherently unreliable nature of the transmission channel introduces delays and errors that compromise the regularity of updating the global model. Furthermore, limited resources and energy consumption of devices are factors that affect FL performance. Therefore, this work proposes a new FL algorithm called FL-E2WS that considers both the requirements of federated training and a wireless network within the scope of the Internet of Things. To reduce the energy cost of devices, FL-E2WS schedules communication resources to allocate the ideal bandwidth and power for the transmission of models under certain device selection and uplink resource block allocation, meeting delay requirements, power consumption, and packet error rate. The simulation results demonstrate that FL-E2WS reduces energy consumption by up to 70.12% and enhances the accuracy of the global model by up to 10.21% compared to the FL algorithms that lacks transmission channel knowledge. Additionally, when compared to FL versions that scale communication resources, FL-E2WS achieves up to a 38.61% reduction in energy consumption and improves the accuracy of the global model by up to 1.61%.
