Performance Evaluation of Algorithms for Wavelength Assignment in Optical Ring Network

A new simulation technique for the performance analysis of First-fit, Random, Most-used and Wavelength conversion Algorithms for wavelength assignment in WDM unidirectional optical ring network are being proposed. The blocking probability of various algorithms with the variation in number of events has been compared. The performance of the wavelength conversion algorithms is best but there is burden of using expensive hardware. Without the need of wavelength-convertor, the Most-used algorithm performs better than the Random and First-fit algorithms. These approaches are very effective for the minimization of blocking probability of optical WDM networks.
