Cet article propose un nouveau schéma d'attribution de slot dynamique (DSA) basé sur une interrogation. Avec les progrès rapides des systèmes d’accès sans fil, la communication de données sans fil deviendra de plus en plus attractive. Dans la communication de données sans fil, un schéma DSA efficace est nécessaire pour améliorer le débit du système, car la capacité des liaisons radio est souvent inférieure à celle des liaisons filaires. Un schéma DSA basé sur une interrogation est généralement utilisé dans les systèmes de contrôle d'attribution de créneaux centralisés. Il est cependant difficile d'attribuer les créneaux horaires aux terminaux mobiles ciblés de manière équitable si seul un système basé sur une interrogation est utilisé, en particulier dans des circonstances de trafic déséquilibré, comme cela sera révélé plus tard. Pour résoudre ce problème, nous proposons un contrôle de débit décroissant exponentiel et croissant proportionnel, comme celui utilisé dans le service à débit binaire disponible (ABR) dans l'ATM, afin qu'une attribution équitable des créneaux soit obtenue même dans des circonstances de trafic fortement déséquilibrées. De plus, afin qu'un point d'accès fonctionnant avec un grand nombre de MT puisse éviter de longs délais de transmission, un système de demande de ressources basé sur une interrogation avec accès aléatoire est présenté dans un nouvel algorithme. Les simulations vérifient que le schéma proposé offre une attribution équitable des créneaux pour chaque utilisateur tout en conservant des performances de débit élevé et de court délai.

Abstract: This paper proposes a new polling-based dynamic slot assignment (DSA) scheme. With the rapid progress of wireless access systems, wireless data communication will become more and more attractive. In wireless data communication, an efficient DSA scheme is required to enhance system throughput, since the capacity of radio links is often smaller than that of wired links. A polling-based DSA scheme is typically used in centralized slot assignment control systems. It, however, is difficult to assign the slots to the targeted mobile terminals in a fair-share manner if only a polling-based scheme is used, especially in unbalanced-traffic circumstances, as revealed later. To solve this problem, we propose the exponential decreasing and proportional increasing rate control as is employed in available bit rate (ABR) service in ATM so that fair slot assignment is achieved even in heavily-unbalanced-traffic circumstances. Moreover, so that an AP operating with a large number of MTs can avoid long transmission delays, a polling-based resource request scheme with random access is featured in a new algorithm. Simulations verify that the proposed scheme offers fair slot assignment for each user while maintaining high throughput and short delay performance.
