Packet error rate and efficiency closed-form expressions for cross-layer hybrid ARQ schemes

For several years, HARQ schemes have been extensively analysed in terms of packet error rate and efficiency at the MAC level. Nevertheless, in order to get realistic performance of the whole system, performance analysis at the IP level is crucial. Therefore, we derive in closed-form expressions the performance (packet error rate and efficiency) of any HARQ scheme (ARQ, incremental redundancy HARQ, chase combining) at the IP level. Moreover cross-layer optimization strategy between MAC and IP layers for HARQ schemes developed initially by for ARQ schemes is considered.
