FCCA: A Reverse-Direction-Based MAC Protocol Suite for WDM Metropolitan Ring Networks

This study investigates the fairness control and collision avoidance issues of a particular WDM dual-ring network known as the FT2-TR2 system. This system is an extended version of the original unidirectional FT-TR ring architecture, in which every node is equipped with a fixed-tuned transmitter and a tunable receiver on each ring. We propose a novel Fairness Control with Collision Avoidance protocol suite, designated FCCA, which comprises of three mechanisms to resolve the receiver collision problem and to achieve fairness among all of the network nodes. The simulation results are presented to demonstrate the effectiveness of the FCCA protocol suite.
