Dynamic compression method for federated learning based on feature information in ISAC networks
To address the communication-efficiency problem of federated learning (FL) in 6G integrated sensing and communication (ISAC) edge networks under limited communication bandwidth
dynamic link conditions
and device heterogeneity
a feature-information-driven collaborative compression and aggregation framework
termed FI-ISAC-FL
was developed. Unlike existing compression methods
federated update compression and aggregation were jointly designed for coordinated adaptation between task-relevant features and system states. Specifically
a Federated-AE online training mechanism was introduced to compress local updates online
by which high-dimensional updates were effectively represented and efficiently transmitted
while the adaptability of compressed representations to data variations was enhanced. In addition
a state-aware adaptive aggregation strategy was developed by incorporating channel states and data-distribution characteristics in ISAC scenarios to improve training stability and efficiency under communication constraints. Simulation results show that
in a radar target recognition task
favorable model performance is achieved under a fixed communication budget
a better trade-off between performance and resource overhead is attained
and strong robustness against severe sensing interference and Non-IID data distributions is demonstrated.
