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

TL;DR

This paper proposes a novel aggregation-based scheduling method for IEEE 802.11ac WiFi channels that transmits multiple copies of MPDUs to enhance throughput in rapidly changing environments.

Contribution

It introduces a new scheduling approach that exploits standard aggregation schemes and duplicate transmissions to significantly improve throughput without link adaptation.

Findings

Achieves tens of percent throughput improvement

Effective in rapidly changing WiFi channels

Operates without link adaptation

Abstract

In this paper we suggest a novel idea to improve the Throughput of a rapidly chang- ing WiFi channel by exploiting the standard aggregation schemes in IEEE 802.11ac networks, and by transmitting several copies of the same MPDU(s) in a single trans- mission attempt. We test this idea in scenarios where Link Adaptation is not used and show a significant improvement, in the order of tens of percents, in the achieved Throughput. Keywords
