No modo de pesquisa centralizado no IEEE 802.16e, uma estação base (BS) pesquisa estações móveis (MSs) para reserva de largura de banda em um dos três modos de pesquisa; pesquisas unicast, multicast ou de transmissão. Na sondagem unicast, a BS sonda cada MS individual para permitir a transmissão de um pacote de solicitação de largura de banda. Este artigo apresenta um modelo analítico para polling unicast de solicitações de largura de banda em redes IEEE 802.16e sobre canal de erro Gilbert-Elliot. Derivamos a distribuição de probabilidade para o atraso de solicitações de largura de banda devido a erros de transmissão sem fio e encontramos a probabilidade de perda de pacotes de solicitação devido a tentativas finitas de retransmissão. Usando a distribuição de atraso e a probabilidade de perda, otimizamos o número de slots de polling dentro de um quadro e o número máximo de retransmissão, ao mesmo tempo em que satisfazemos a QoS na probabilidade de perda total que combina duas perdas: perda de pacotes devido ao excesso da retransmissão máxima e interrupção de atraso. perda devido ao limite máximo de atraso tolerável. Além disso, obtemos a utilização de slots de polling, que é definida como a razão entre o número de slots de polling usados para a transmissão bem-sucedida da MS e o número total de slots de polling usados pela MS durante um longo tempo de execução. Os resultados da análise mostram uma boa correspondência com os resultados da simulação. Os resultados numéricos fornecem exemplos do número ideal de slots de pesquisa dentro de um quadro e do número máximo ideal de retransmissão dependendo dos limites de atraso, do número de MSs e das condições do 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.

AB - 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.

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.
