Un nouveau protocole MAC utilisant l'Adaptive Weighted Round Robin with Delay Tolerance (AWRR/DT) est présenté. Le protocole proposé est un type de protocole MAC centralisé dans lequel la station de base effectue la plupart des opérations. En utilisant le planificateur AWRR/DT, nous pouvons garantir la QoS de retard pour différents trafics sans la lourde surcharge induite par les techniques de marquage basées sur les paquets. Afin d'améliorer l'efficacité des systèmes d'accès aléatoire, le protocole proposé utilise trois nouvelles méthodes de contention : ALOHA à créneaux avec seuil, méthode de contention utilisant une période de contention adaptative et méthode de contention spécifique au trafic. Les résultats de simulation montrent que le protocole proposé garantit les limites de délai en utilisant l'AWRR/DT. L'ALOHA à fentes avec seuil subit moins de collisions que l'ALOHA à fentes régulière lorsque les terminaux mobiles demandent des emplacements. Le procédé utilisant une période de contention adaptative ajuste la durée de la période de contention de chaque trame pour atténuer la dégradation des performances due aux collisions. La méthode de contention spécifique au trafic fournit un mécanisme de gestion des priorités aux systèmes basés sur les conflits. Les résultats expérimentaux de chaque méthode de contention sont fournis.

Abstract: A new MAC protocol using the Adaptive Weighted Round Robin with Delay Tolerance (AWRR/DT) is presented. The proposed protocol is a type of centralized MAC protocol where the base station performs most operations. By using the AWRR/DT scheduler, we can guarantee delay QoS to different traffics without the heavy overhead induced by packet-based tagging techniques. In order to enhance the efficiency of random access systems, the proposed protocol employs three novel contention methods: slotted ALOHA with threshold, contention method using adaptive contention period, and traffic-specific contention method. Simulation results show that the proposed protocol guarantees delay bounds by using the AWRR/DT. The slotted ALOHA with threshold suffers less collisions than the regular slotted ALOHA when mobile terminals request slots. The method using adaptive contention period adjusts the length of contention period of each frame to relieve the performance degradation by collisions. The traffic-specific contention method provides a priority handling mechanism to contention-based systems. Experimental results of each contention method are provided.
