Optimized Network Coding with Real-Time Loss Prediction for Hybrid 5G Networks.

Two novel mechanisms are introduced to take advantage of network coding in TCP (Transmission Control Protocol), namely: TCP with Network-Coded Window Transformation (TCP-NWT) and TCP-NWT augmented with dynamic loss prediction, called Predictive-Network-Coding (TCP-PNC). TCP-NWT uses network coding to handle packet losses without retransmissions. TCP-PNC predicts the expected loss-ratio on an ongoing basis during the course of a TCP-NWT session, which in turn changes the number of network coded packets that are transmitted. These mechanisms result in a more efficient use of network-coded packet transmissions in TCP. Simulation results indicate a throughput increase of more than 22% compared to TCP in scenarios involving dynamic changes in loss ratios in the midst of a TCP session.
