[en] ALLOCATION OF WAVELENGTH CONVERTERS IN PARTIAL NETWORKS / [pt] ALOCAÇÃO DE CONVERSORES DE COMPRIMENTO DE ONDA EM REDES PARCIAIS

MARCELO DE OLIVEIRA LOMONACO 09 April 2007 (has links)
[pt] Este trabalho investiga o problema de alocação sub-óptima de conversores de comprimento de onda em nós de redes ópticas parciais, através da proposição de 3 algoritmos baseados nas metaheurísticas GA (Algoritmo Genético), PSO (Optimização por Enxame de Partícula) e SA (Recozimento Simulado). Simulações são apresentadas para ratificar os benefícios com a introdução de conversores nas arquiteturas de rede. Os desempenhos dos algoritmos são mensurados via um simulador, comparando-os com outros algoritmos estabelecidos na literatura. / [en] This work investigates the problem of suboptimally placing wavelength converters at nodes of partial optical networks, through the proposition of 3 algorithms based on the metaheuristics GA (Genetic Algorithm), PSO (Particle Swarm Optimization) and SA (Simulated Annealing). Simulations are presented to ratify the benefits with the introduction of wavelength converters on networks architectures. The results of these algorithms are measure by a simulator, comparing them with other algorithms in literature.
