Paper Abstract

We first propose the genetic algorithms (GA) to deal with strictly non-blocking grooming problems in optical tree networks. We describe strictly non-blocking grooming problems in Wavelength Division Multiplexing (WDM) optical trees with traffics and find the lower and upper bounds. Here we use the (μ + λ)-strategy to produce offspring for the genetic algorithm, and apply the technology of wavelengths-reuse in the decoding of the individual in the genetic algorithms. The performance of the proposed strictly non-blocking grooming algorithm was tested in tree networks with different granularity and different number of traffic patterns. Computer simulation results show that our algorithm can achieve very good results in saving both ADM's and wavelength in tree networks.
