About this paper

Samer Lahoud, Kinda Khawam

Researchers propose a federated semantic communication framework for heterogeneous IoT networks that integrates semantic feature transmission with adaptive client selection and a loss-based aggregation mechanism. The work demonstrates that a Proportional Fairness client selection strategy can achieve competitive image reconstruction quality (30.6 dB PSNR) while significantly improving fairness (36% better effort equality) and computational efficiency (4.8x gain) compared to a baseline.

Key insights

  • A clear trade-off exists between maximizing reconstruction quality, ensuring fairness in client participation, and achieving computational efficiency in federated semantic communication systems.
  • Proportional Fairness client selection offers a strong balance, yielding competitive performance while significantly improving fairness and computational efficiency, making it suitable for sustainable IoT deployments.
  • Intelligent client selection, combined with a loss-based aggregation mechanism, effectively mitigates challenges posed by client heterogeneity (non-IID data, varying resource capabilities) in federated learning.
