La demande d'utilisation d'applications qui supposent une communication bidirectionnelle telle que la téléphonie vocale et le peer-to-peer utilisant des stations sans fil a augmenté et, en particulier, on s'attend à une augmentation rapide du trafic de liaison montante à partir de terminaux sans fil. Cependant, dans les WLAN montants, le problème des stations cachées reste à résoudre. Dans cet article, nous soulignons ce problème de station cachée et clarifions l'injustice suivante entre les flux de liaison montante UDP et TCP : 1) l'effet de la collision provoquée par la relation de station cachée sur le débit et 2) l'instabilité du débit en fonction du nombre de stations cachées. de stations cachées. Pour résoudre ces problèmes, nous proposons un mécanisme d’accès virtuel multi-AP. Notre mécanisme regroupe d'abord les stations en fonction de la relation entre les stations cachées et du type de protocole de transport qu'elles utilisent, puis attribue un canal virtuellement isolé à chaque groupe, ce qui permet aux STA de communiquer comme si les STA de différents groupes étaient connectées à différents AP isolés (AP virtuels : VAP). Il peut atténuer l'effet provoqué par les collisions entre les stations cachées et éliminer les conflits entre les flux de liaison montante UDP et TCP. Ses performances sont démontrées par simulation.

Abstract: The demand of using applications that assume bidirectional communication such as voice telephony and peer-to-peer using wireless stations has been increasing and especially, the rapid increase of uplink traffic from wireless terminals is expected. However, in uplink WLANs, the hidden-station problem remains to be solved. In this paper, we point out this hidden-station problem and clarify the following unfairness between UDP and TCP uplink flows: 1) the effect of collision caused by hidden-station relationship on throughput and 2) the instability of the throughput depending on the number of hidden stations. To solve these problems, we propose a virtual multi-AP access mechanism. Our mechanism first groups stations according to the hidden-station relationship and type of transport protocol they use then assigns a virtually isolated channel to each group, which enables STAs to communicate as if STAs in different groups are connected to different isolated APs (virtual APs: VAPs). It can mitigate the effect caused by collisions between hidden stations and eliminate the contention between UDP and TCP uplink flows. Its performance is shown through simulation.
