Dans cet article, nous analysons l'algorithme ertPS (Extended Real-Time Polling Service) dans les systèmes IEEE 802.16e, conçu pour prendre en charge les services Voice-over-Internet-Protocol (VoIP) avec des paquets de données de différentes tailles et la suppression du silence. L'analyse utilise une chaîne de Markov bidimensionnelle, où la taille de l'octroi et l'état du paquet vocal sont prises en compte, et une formule d'approximation du débit total dans l'algorithme ertPS est dérivée. Ensuite, pour améliorer les performances de l'algorithme ertPS, nous proposons un algorithme amélioré d'allocation de ressources de liaison montante, appelé e 2Algorithme rtPS, pour les services VoIP dans les systèmes IEEE 802.16e. Le e 2L'algorithme rtPS prend en compte les informations sur l'état de la file d'attente et tente de réduire la congestion de la file d'attente dès que possible en utilisant les ressources réseau restantes. Des résultats numériques sont fournis pour montrer l'exactitude de l'analyse d'approximation pour l'algorithme ertPS et pour vérifier l'efficacité de l'e 2Algorithme rtPS.

Abstract: In this paper, we analyze the extended real-time Polling Service (ertPS) algorithm in IEEE 802.16e systems, which is designed to support Voice-over-Internet-Protocol (VoIP) services with data packets of various sizes and silence suppression. The analysis uses a two-dimensional Markov Chain, where the grant size and the voice packet state are considered, and an approximation formula for the total throughput in the ertPS algorithm is derived. Next, to improve the performance of the ertPS algorithm, we propose an enhanced uplink resource allocation algorithm, called the e 2rtPS algorithm, for VoIP services in IEEE 802.16e systems. The e 2rtPS algorithm considers the queue status information and tries to alleviate the queue congestion as soon as possible by using remaining network resources. Numerical results are provided to show the accuracy of the approximation analysis for the ertPS algorithm and to verify the effectiveness of the e 2rtPS algorithm.
