O protocolo de acesso múltiplo de reserva de pacotes sem colisão (NC-PRMA) foi proposto para comunicações de voz sem fio. Nesse protocolo, embora possa evitar qualquer colisão usando minislot de controle, o terminal que gera seu surto de fala em um quadro atual tem que esperar até um próximo quadro para transmitir um pacote solicitante para obter reserva. Além disso, sob tráfego integrado de voz e dados, no NC-PRMA convencional a probabilidade de queda de pacotes de voz torna-se pior, devido ao número de slots que os terminais de voz podem acessar ser limitado. Neste artigo, propomos o NC-PRMA com transmissão aleatória para slots ociosos. Primeiro, avaliamos o atraso médio de acesso e a probabilidade de queda de pacotes de voz apenas sob tráfego de voz pela análise teórica e pela simulação computacional. É mostrado que o esquema proposto atinge atraso médio de acesso menor que o NC-PRMA convencional. A seguir, avaliamos o atraso do pacote de dados e a probabilidade de queda do pacote de voz sob tráfego integrado de voz e dados pela simulação computacional. É mostrado que o esquema proposto atinge menor probabilidade de queda de pacotes do que o PRMA e o NC-PRMA convencional.

Abstract: The non-collision packet reservation multiple access (NC-PRMA) protocol has been proposed for wireless voice communications. In that protocol, although it can avoid any collision by using control minislot, the terminal which generates its talkspurt in a current frame has to wait till a next frame to transmit an asking packet to obtain reservation. Furthermore, under integrated voice and data traffic, in the conventional NC-PRMA the voice packet dropping probability becomes worse, because of the number of slots that voice terminals can access are limited. In this paper, we propose the NC-PRMA with random transmission to idle slots. First, we evaluate the mean access delay and the voice packet dropping probability under only voice traffic by the theoretical analysis and the computer simulation. It is shown that the proposed scheme attains lower mean access delay than the conventional NC-PRMA. Next, we evaluate the data packet delay and the voice packet dropping probability under integrated voice and data traffic by the computer simulation. It is shown that the proposed scheme attains lower packet dropping probability than the PRMA and the conventional NC-PRMA.
