Dans le mode d'interrogation centralisé dans IEEE 802.16e, une station de base (BS) interroge les stations mobiles (MS) pour la réservation de bande passante dans l'un des trois modes d'interrogation ; sondages en monodiffusion, multidiffusion ou diffusion. Lors d'une interrogation en monodiffusion, la BS interroge chaque MS individuelle pour permettre la transmission d'un paquet de demande de bande passante. Cet article présente un modèle analytique pour l'interrogation en monodiffusion des demandes de bande passante dans les réseaux IEEE 802.16e sur le canal d'erreur Gilbert-Elliot. Nous dérivons la distribution de probabilité du retard des demandes de bande passante dû à des erreurs de transmission sans fil et trouvons la probabilité de perte des paquets de requêtes en raison de tentatives de retransmission finies. En utilisant la distribution des délais et la probabilité de perte, nous optimisons le nombre de slots d'interrogation dans une trame et le nombre maximum de retransmission tout en satisfaisant la QoS sur la probabilité de perte totale qui combine deux pertes : la perte de paquets due au dépassement du maximum de retransmission et la panne de délai. perte due au délai maximum tolérable fixé. De plus, nous obtenons l'utilisation des créneaux d'interrogation, qui est définie comme le rapport entre le nombre d'intervalles d'interrogation utilisés pour la transmission réussie de la MS et le nombre total d'intervalles d'interrogation utilisés par la MS sur une longue période. Il apparaît que les résultats de l'analyse correspondent bien aux résultats de la simulation. Les résultats numériques donnent des exemples du nombre optimal d'intervalles d'interrogation dans une trame et du nombre maximal de retransmission optimal en fonction des limites de retard, du nombre de MS et des conditions du canal.

Abstract: In the centralized polling mode in IEEE 802.16e, a base station (BS) polls mobile stations (MSs) for bandwidth reservation in one of three polling modes; unicast, multicast, or broadcast pollings. In unicast polling, the BS polls each individual MS to allow to transmit a bandwidth request packet. This paper presents an analytical model for the unicast polling of bandwidth request in IEEE 802.16e networks over Gilbert-Elliot error channel. We derive the probability distribution for the delay of bandwidth requests due to wireless transmission errors and find the loss probability of request packets due to finite retransmission attempts. By using the delay distribution and the loss probability, we optimize the number of polling slots within a frame and the maximum retransmission number while satisfying QoS on the total loss probability which combines two losses: packet loss due to the excess of maximum retransmission and delay outage loss due to the maximum tolerable delay bound. In addition, we obtain the utilization of polling slots, which is defined as the ratio of the number of polling slots used for the MS's successful transmission to the total number of polling slots used by the MS over a long run time. Analysis results are shown to well match with simulation results. Numerical results give examples of the optimal number of polling slots within a frame and the optimal maximum retransmission number depending on delay bounds, the number of MSs, and the channel conditions.

In unicast polling, the BS polls each individual MS to allow to transmit a bandwidth request packet.
