The IEEE 802.11n network main feature is to support high throughput of more than 100Mbps at the MAC layer. To achieve this, the 802.11n Task Group has introduced frame aggregation technique which reduces the overhead and increases the channel utilization efficiency. Some recent researches have enabled an A-MSDU selective retransmission which makes it robust against error. In this paper, the authors propose a scheduler based on an A-MSDU aggregation mechanism that supports small size and high sensitivity traffics, and enable prioritization according to the QoS requirements of the traffic classes.
