RODRIGUEZ, Arturo B; SAAVEDRA, Fideromo  and  RAMIREZ, Leonardo J. Metaheuristic Strategy for Dynamic Traffic in Wavelength Division Multiplexing Optical Networks (WDM). Inf. tecnol. [online]. 2016, vol.27, n.5, pp.221-230. ISSN 0718-0764.

This research shows the performance comparison between different heuristico such as genetic algorithms, simulated annealing, Tabu Search, Snake-One and a new metaheuristic called Snake-Two. Varlier were obtained low blocking probability but with a tendency to increase network utilization. The new Snake-Two strategy can prove that the behavior of the blocking probability decreases at low network usage. These results are compared with a conventional algorithm that was used to visualize the improvement of each indicator. The indicators used for comparison, are the blocking probability and the network utilization and a new indicator called Heuristic Algorithm Rate. This strategy proposeo using the congeoted links, allowing increasing the traffic in some areas, and reducing it in other areas. The results are promising to achieve lower blocking probability but the tendency of increasing the use of the network resources continues.

Keywords : simulated annealing; genetics algorithm; active contour model; snakes methods.
