Abstract

We introduce a queuing subsystem to an optical random access CDMA protocol, namely, the round robin receiver/transmitter (R 3T) protocol. A detailed state diagram is outlined and a mathematical model based on the equilibrium point analysis (EPA) is presented. In addition, the steady state system throughput, the average packet delay, and the blocking probability are derived and evaluated under several network parameters. We prove by numerical analysis that significant improvement in the protocol's performance can be achieved by only adding a single buffer to the system. The blocking probability is significantly reduced by a factor of 50 %. Our results also reveal that the modified R 3T protocol can support higher traffic loads. Further, queuing delays that added to the total network latency are acceptable.
