Solving the RWA Problem in WDM Optical Networks Using the BCO Meta-Heuristic

This paper researches the Routing and Wavelength Assignment (RWA) problem in wavelength routed optical WDM networks with the wavelength conversion capability at different network nodes. The authors studied the static case in which all connection requests are known in advance, thus a routing decision can be made based on the complete knowledge of the traffic to be served by the network. The Bee Colony Optimization (BCO) metaheuristic is applied to solve the RWA problem. They carried out a comprehensive simulation study of the performance of the proposed BCORWA algorithm for different network topologies and traffic scenarios. The obtained simulation results are analyzed and compared.
