Optical CDMA protocol with selective retransmission

New protocol for optical code-division multiple access (CDMA) networks is proposed. Our proposed protocol is based on selective retransmission technique. A mathematical model is presented using a detailed state diagram. The protocol is analyzed using equilibrium point analysis (EPA), and its performance is examined using traditional throughput and average delay for several network parameters. We also compare the performance of the proposed protocol to the R³T protocol based on go-back-n technique. Results show that a higher performance is achieved by the proposed protocol at the expense of system complexity.
