IEEE 802.11 무선 LAN(WLAN) 환경에서 TCP 처리량의 흐름별 불공정성은 과거 문헌에서 보고되었습니다. 많은 연구자들은 이러한 불공정함을 완화하기 위한 다양한 방법을 제안해 왔다. 대부분의 경우 액세스 포인트의 MAC 프로토콜이나 대기열 관리 메커니즘을 수정해야 합니다. 그러나 액세스 포인트의 MAC 프로토콜은 일반적으로 하드웨어 수준에서 구현되므로 이러한 프로토콜을 변경하는 데 비용이 많이 듭니다. 본 논문의 첫 번째 공헌으로 우리는 TCP 흐름 간의 불공평성을 완화하기 위한 전송 계층 솔루션을 제안하며, WLAN 스테이션에서만 TCP 혼잡 제어 메커니즘을 약간 수정해야 합니다. 인터넷 흐름의 공정성 문제에 관한 과거 문헌에서 불공정성을 완화하기 위해 제안된 솔루션의 성능은 네트워크 대역폭 활용도와 별도로 평가되었습니다. 이는 공정성과 대역폭 활용도 간의 균형 관계를 고려하지 않았음을 의미합니다. 따라서 본 문서의 두 번째 공헌으로 네트워크 병목 현상 시 흐름별 공정성과 대역폭 활용도 간의 균형 관계를 평가하기 위한 새로운 성능 측정 기준을 소개합니다. 제안한 방법의 기본 특성을 시뮬레이션 실험을 통해 확인하고, 실제 WLAN 환경에서의 실험을 통해 제안한 방법의 성능을 평가한다. 우리는 제안된 방법이 무선 액세스 포인트와 무선 인터페이스 카드의 벤더 구현에 관계없이 공정성과 대역폭 활용 사이의 더 나은 균형을 달성할 수 있음을 보여줍니다.

Abstract: Per-flow unfairness of TCP throughput in the IEEE 802.11 wireless LAN (WLAN) environment has been reported in past literature. A number of researchers have proposed various methods for alleviating the unfairness; most require modification of MAC protocols or queue management mechanisms in access points. However, the MAC protocols of access points are generally implemented at hardware level, so changing these protocols is costly. As the first contribution of this paper, we propose a transport-layer solution for alleviating unfairness among TCP flows, requiring a small modification to TCP congestion control mechanisms only on WLAN stations. In the past literature on fairness issues in the Internet flows, the performance of the proposed solutions for alleviating the unfairness has been evaluated separately from the network bandwidth utilization, meaning that they did not consider the trade-off relationships between fairness and bandwidth utilization. Therefore, as the second contribution of this paper, we introduce a novel performance metric for evaluating trade-off relationships between per-flow fairness and bandwidth utilization at the network bottleneck. We confirm the fundamental characteristics of the proposed method through simulation experiments and evaluate the performance of the proposed method through experiments in real WLAN environments. We show that the proposed method can achieve better a trade-off between fairness and bandwidth utilization, regardless of vendor implementations of wireless access points and wireless interface cards.
