A New Aggregation based Scheduling method for rapidly changing IEEE 802.11ac Wireless channels.

In this paper we suggest a novel idea toimprove the Throughput of a rapidly changing WiFi channel by exploiting thestandard aggregation schemes in IEEE 802.11ac networks. The idea is based onblindly transmitting several copies of the first 4 MAC Protocol Data Units(MPDU) in the Transmission Window. This increases the probability that thewindow moves forward, enabling the transmission of new MPDUs and resulting inincreased Throughput. It turns out that transmitting 2 copies of each of thefirst 4 MPDUs yields the best Throughput gain, in the order of 50% - 60% in PHYrates of 1.3 - 3.5 Gbps and few hundreds of bytes MPDUs. The proposed idea hasadvantage over Link Adaptation since it reduces the actual PHY rate only forthe transmission of few MPDUs while Link Adaptation reduces the PHY rate forall the transmissions.
