Cet article propose un service VoIP sans fil multicouche qui intègre un algorithme AQP (Adaptive QoS Playout), un modèle E, un protocole de transmission de contrôle de flux (SCTP), un middleware IEEE 802.21 Media Independent Handover (MIH) et deux services de détection de mouvement utilisateur. L'algorithme AQP proposé intègre l'effet du contrôle de diffusion et de la retransmission des paquets perdus sur la base du modèle E. En outre, en utilisant le service de transmission partiellement fiable de SCTP et la notification de transfert des services MIH de manière intercouche, AQP peut réduire le taux de perte de retard et améliorer la qualité de la parole dans des taux d'erreur de trame élevés. Dans les simulations, les performances d'AQP sont comparées à un algorithme de diffusion fixe et à quatre stratégies de diffusion adaptatives. Les résultats de la simulation montrent que le taux de perte de retard d'AQP est 2 % inférieur à celui des algorithmes de diffusion existants et que le facteur R est 16 % supérieur à celui des algorithmes comparés lorsqu'un réseau a un délai de propagation filaire de 50 ms et un taux d'erreur de trame de 2.5 %.

Abstract: This paper proposes a cross layer wireless VoIP service which integrates an Adaptive QoS Playout (AQP) algorithm, E-model, Stream Control Transmission Protocol (SCTP), IEEE 802.21 Media Independent Handover (MIH) middleware and two user motion detection services. The proposed AQP algorithm integrates the effect of playout control and lost packet retransmission based on the E-model. Besides, by using the partial reliable transmission service from SCTP and the handoff notification from MIH services in a cross layer manner, AQP can reduce the lateness loss rate and improve speech quality under high frame error rates. In the simulations, the performance of AQP is compared with a fixed playout algorithm and four adaptive playout strategies. The simulation results show that the lateness loss rate of AQP is 2% lower than that of existing playout algorithms and the R-factor is 16% higher than the compared algorithms when a network has 50 ms wired propagation delay and 2.5% frame error rate.
