Performance optimization with propagation delay analysis in WDM networks

In this study we attempt to analyze a synchronous transmission WDMA protocol for passive star topology based on the propagation delay latency effect. The introduction of propagation delay constitutes a serious parameter for WDM networks performance behavior and a realistic basis for the analysis. The proposed WDM network uses a Multi-channel Control Architecture (MCA) for two reasons: First to reduce the electronic processing bottleneck and second to optimize the performance measures by dynamically dividing the control channels into two groups according to the knowledge of the stations status (free or backlogged). In this way we develop a Markovian model for finite population with receiver collisions evaluation. (c) 2007 Elsevier B.V. All rights reserved.
