abstract = "In this paper, we propose a hybrid methodology based on
Graph-Coloring and Genetic Algorithm (GA) to solve the Wavelength
Assignment (WA) problem in optical networks, impaired by physical
layer effects. Our proposal was developed for a static scenario
where the physical topology and traffic matrix are known a priori.
First, we used fixed shortest-path routing to attend demand
requests over the physical topology and the graph-coloring
algorithm to minimize the number of necessary wavelengths. Then,
we applied the genetic algorithm to solve WA. The GA finds the
wavelength activation order on the wavelengths grid with the aim
of reducing the Cross-Phase Modulation (XPM) effect; the variance
due to the XPM was used as a function of fitness to evaluate the
feasibility of the selected WA solution. Its performance is
compared with the First-Fit algorithm in two different scenarios,
and has shown a reduction in blocking probability up to 37.14%
when considered both XPM and residual dispersion effects and up to
71.42% when only considered XPM effect. Moreover, it was possible
to reduce by 57.14% the number of wavelengths.",
