This paper studies the problem of dynamic Routing and Wavelength Assignment (RWA) in Wavelength Division Multiplexed (WDM) networks with the wavelength the continuity constraint applied. A hybrid algorithm using Particle Swarm Optimization (PSO), inspired by an Ant System (AS), is used. For the routing sub-problem, particles of the swarm use the tour building approach of AS together with the exploration and exploitation approach of PSO. For the wavelength sub-problem, a first-fit algorithm is… CONTINUE READING
