Para melhorar a confiabilidade e a eficiência das transmissões multicast em sistemas sem fio, é desejado um novo procedimento de retransmissão. Neste artigo, é proposto um esquema de reconhecimento representativo para comunicações multicast sem fio confiáveis, que oferece uma taxa de perda de pacotes bastante baixa. O protocolo proposto realiza retransmissões na camada de enlace de dados dentro da região sem fio, e as retransmissões não afetam o tráfego na região cabeada. O esquema de reconhecimento representativo emprega tanto o reconhecimento positivo (ACK) quanto o reconhecimento negativo (NACK) para obter transmissões multicast confiáveis e reduz o número de respostas a serem retornadas pela formação de grupos de estações na célula. Um dos membros de um grupo, denominado estação representativa, retorna uma resposta para um quadro de dados recebido enquanto os outros retornam um NACK, se necessário. Com este esquema, transmissões multicast confiáveis são habilitadas em comunicações sem fio sem gastar muito tempo como nos protocolos multicast confiáveis convencionais. O desempenho do protocolo proposto é avaliado por análises numéricas e por simulação computacional. Os resultados mostram que uma redução de 30% ou mais no tempo de transmissão é alcançada em um ambiente sem fio típico.

Abstract: To improve the reliability and efficiency of multicast transmissions in wireless systems, a novel retransmission procedure is desired. In this paper, the representative acknowledgment scheme for reliable wireless multicast communications is proposed that offers quite a low packet loss rate. The proposed protocol carries out retransmissions in the datalink layer within the wireless region, and retransmissions do not affect the traffic in the wired region. The representative acknowledgment scheme employs both positive acknowledgment (ACK) and negative acknowledgment (NACK) to achieve reliable multicast transmissions and reduces the number of responses to be returned by forming groups of stations in the cell. One of the members in a group, called a representative station, returns a response for a received data frame while the others return a NACK if necessary. With this scheme, reliable multicast transmissions are enabled in wireless communications without spending much time as in conventional reliable multicast protocols. The performance of the proposed protocol is evaluated by numerical analyses and by computer simulation. The results show that 30% or more decrease in transmission time is achieved in a typical wireless environment.
