Dalam kertas kerja ini, kami mencadangkan penyelesaian baharu untuk meningkatkan kualiti saluran wayarles rangkaian kawasan setempat (WLAN) tanpa wayar dalam persekitaran mudah alih pantas, yang menggunakan pendekatan lapisan media-access-control (MAC): kawalan panjang bingkai adaptif dan pengakuan blok. (ACK). Dalam persekitaran mudah alih pantas, menggunakan panjang bingkai pendek boleh menyekat ralat anggaran saluran dan mengurangkan ralat bingkai. Walau bagaimanapun, ia meningkatkan overhed MAC, mengakibatkan daya tampung menurun. Untuk menyelesaikan pertukaran ini, kami menggabungkan blok ACK, yang dinyatakan dalam IEEE802.11e sebagai fungsi pilihan, dengan kawalan panjang bingkai penyesuaian. Walaupun kawalan panjang bingkai adaptif memandangkan pertukaran ini telah disiasat sebelum ini, sasaran adalah berbeza daripada WLAN yang menggunakan pemultipleksan bahagian frekuensi ortogon (OFDM) dalam persekitaran mudah alih pantas. Pengurangan overhed MAC menggunakan blok ACK sesuai untuk kawalan panjang bingkai kami kerana ia tidak mengubah format bingkai dalam lapisan fizikal. Selain itu, adalah idea baharu untuk menggunakan blok ACK sebagai penyelesaian untuk meningkatkan kualiti saluran dalam persekitaran mudah alih pantas. Dalam makalah ini, kami menilai kaedah kami melalui simulasi komputer dan mengesahkan keberkesanan kawalan panjang bingkai penyesuaian yang boleh menampung kelajuan relatif.

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.
