Abstract

A random access protocol that adopts stop-and-wait automatic repeat request (ARQ) is proposed for optical code-division multiple-access (CDMA) communication systems. A detailed state diagram and a mathematical model based on the equilibrium point analysis (EPA) technique are presented. Several performance measures are evaluated under different network parameters. In addition, the performance of the proposed protocol is compared to that of the round-robin receiver/transmitter (R³T) protocol, which is based on a go-back-n-technique. The ALOHA CDMA protocol is also considered. Finally, our protocol is analyzed when a queuing subsystem is added. Our numerical analysis shows that the proposed protocol is less complex and significantly outperforms the R³T protocol. We show that adding a single buffer to the system does not improve the performance much.
