Abstract :
In this paper, a novel chaotic particle swarm optimization (CPSO) based scheme is proposed for solving dynamic routing and wavelength assignment problem in all-optical WDM networks without any wavelength conversion. A novel fitness function is proposed to improve the connection blocking probability by taking into account normalized path length and wavelength availability over the whole path. Simulation results show that CPSO not only performs better in terms of connection blocking probability performance as compared to other heuristic schemes like genetic algorithms, it also presents better solution quality as compared to particle swarm optimization (PSO).
