Abstract :
In this paper, we evaluate the throughput performance of Hybrid Automatic Repeat reQuest (HARQ) protocols using Adaptive Modulation and Coding (AMC) based on either the instantaneous Signal to Noise Ratio (SNR) or the average SNR. We also propose a cross layer optimization algorithm in order to offer the highest throughput at the physical (PHY) layer and verify some Quality Of Service (QOS) constraints at the Medium Access (MAC) layer such as the Probability of Packet Erasure (PPE) and the transmission delay. Simulation results are also provided in different contexts in order to verify the tightness of the derived results.
