Reconfiguration Algorithms Based on META-Heuristics for Multihop WDM Lightwave Networks

The logical configuration of a WDM network can be changed by reassigning wavelengths to tunable transceivers of nodes. In this paper, we develop reconfiguration algorithms to obtain an optimal node placement of multihop networks with regular topology. The algorithms are based on meta-heuristics such as simulated annealing, threshold acceptance, and multistart local search. We compare the performance of these algorithms in terms of their calculation time required to reach a solution with accuracy of some given degree.
