Abstract :
In this letter, we propose an application-aware modulation and coding scheme (MCS) level selection method for a cross-layered retransmission scheme. The existing MCS level selection methods use fixed target packet error rate (PER) only and do not take into account quality of service (QoS) requirements for an application. This may cause a discrepancy between the QoS requirements of an application and the criterion for selection of an MCS level. Therefore, the channel utilization is decreased due to the discrepancy. To remove the discrepancy, the application-aware MCS level selection method adjusts a target PER according to the type of application. We have shown that the proposed scheme can improve the wireless channel utilization.
