Neste artigo, propomos uma nova solução para melhorar a qualidade do canal sem fio de redes locais sem fio (WLANs) em ambientes móveis rápidos, que utiliza uma abordagem de camada de controle de acesso à mídia (MAC): controle adaptativo de comprimento de quadro e reconhecimento de bloco. (ACK). Em ambientes móveis rápidos, o uso de comprimentos de quadro curtos pode suprimir erros de estimativa de canal e diminuir erros de quadro. No entanto, aumenta a sobrecarga do MAC, resultando em diminuição do rendimento. Para resolver essa compensação, combinamos o bloco ACK, especificado em IEEE802.11e como uma função opcional, com controle adaptativo de comprimento de quadro. Embora o controle adaptativo do comprimento do quadro considerando essa compensação tenha sido investigado anteriormente, os alvos eram diferentes das WLANs que usam multiplexação por divisão de frequência ortogonal (OFDM) em ambientes móveis rápidos. A redução do overhead MAC usando o bloco ACK é adequada para nosso controle de comprimento de quadro porque não altera o formato do quadro na camada física. Além disso, é uma ideia nova usar o bloco ACK como uma solução para melhorar a qualidade do canal em ambientes móveis rápidos. Neste artigo, avaliamos nosso método através de simulações computacionais e verificamos a eficácia do controle adaptativo do comprimento do quadro que pode acomodar velocidades relativas.

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.
