Dynamic and Low-Cost TWDM-PON Resource Allocation for NG-RAN Fronthaul with Multi-cell Traffic Predictions

This work proposed an N-steps ahead max First-Fit algorithm with multi-cell traffic predictions to achieve adaptive resource allocation with low resource consumption and reconfiguration cost. Simulation results indicate that the traffic prediction precision can reach 95%, and the proposed algorithm can reduce the reconfiguration cost about fourfold with additional 0.75 wavelengths utilization in average, compared to the baseline.
