본 논문에서는 미디어 액세스 제어(MAC) 계층 접근 방식인 적응형 프레임 길이 제어 및 블록 승인을 사용하여 고속 모바일 환경에서 무선 근거리 통신망(WLAN)의 무선 채널 품질을 향상시키는 새로운 솔루션을 제안합니다. (ACK). 빠른 모바일 환경에서는 짧은 프레임 길이를 사용하면 채널 추정 오류를 억제하고 프레임 오류를 줄일 수 있습니다. 그러나 MAC 오버헤드가 증가하여 처리량이 감소합니다. 이러한 상충관계를 해결하기 위해 우리는 IEEE802.11e에서 선택적 기능으로 지정된 블록 ACK를 적응형 프레임 길이 제어와 결합했습니다. 이러한 트레이드오프를 고려한 적응형 프레임 길이 제어가 이전에 조사되었지만 대상은 고속 모바일 환경에서 OFDM(직교 주파수 분할 다중화)을 사용하는 WLAN과 달랐습니다. 블록 ACK를 이용한 MAC-오버헤드 감소는 물리 계층에서 프레임 형식을 변경하지 않기 때문에 프레임 길이 제어에 적합합니다. 또한, 빠른 모바일 환경에서 채널 품질을 향상시키기 위한 솔루션으로 블록 ACK를 사용하는 것도 새로운 아이디어입니다. 본 논문에서는 컴퓨터 시뮬레이션을 통해 방법을 평가하고 상대 속도를 수용할 수 있는 적응형 프레임 길이 제어의 효율성을 검증합니다.

Abstract: In this paper, we propose a novel solution to improving wireless channel quality of wireless local area networks (WLANs) in fast-mobile environments, which uses a media-access-control (MAC) layer approach: adaptive frame-length control and block acknowledgement (ACK). In fast-mobile environments, using short frame lengths can suppress channel estimation error and decrease frame errors. However, it increases the MAC overhead, resulting in decreased throughput. To solve this tradeoff, we combined block ACK, which is specified in IEEE802.11e as an optional function, with adaptive frame-length control. Although adaptive frame-length control considering this tradeoff has previously been investigated, the targets were different from WLANs using orthogonal frequency division multiplexing (OFDM) in fast-mobile environments. The MAC-overhead reduction using block ACK is suitable for our frame-length control because it does not change the frame format in the physical layer. Also, it is a new idea to use block ACK as a solution to improving channel quality in fast-mobile environments. In this paper, we evaluate our method through computer simulations and verify the effectiveness of adaptive frame-length control that can accommodate relative speeds.
