Heterogeneous Graph Neural Network-Based Collaborative Spectrum Management for Multi-Node Frequency-Usage Network
The simulation results demonstrate that the proposed HGNN framework achieves steady-state utility gains of approximately 7.1% and 1.4% over the SL-GNN in 48-node and 81-node scenarios, respectively, along with corresponding Interference Suppression Ratio (ISR) improvements of 1.5 dB and 2.9 dB against the SL-GNN.
