A Dynamic Procedure with Propagation Delay Analysis for Performance Optimization in WDM Networks

This paper presents a synchronous transmission WDMA protocol for passive star topology. The network architecture adopts the multi-channel control architecture (MCA) [2] to exchange control information. In our analysis, we exploit the effect of propagation delay latency to improve the system utilization by dynamically dividing the MCA into two groups of channels based on the knowledge of the stations status (free or backlogged). Also, the combination with the access algorithm introduced in [3] that avoids data channel collisions gives optimum results improving even more the performance. An analytic Morkovian model for finite population is developed considering the effect of receiver collisions to performance measures evaluation.
