Greedy Algorithm for Reducing FWM Impairments in Dynamic Optical Networks

Abstract

(cid:151)This work presents a study on impact of Four Wave Mixing in dynamic optical networks. A simple algorithm is proposed in order to manage Four Wave Mixing impairments. Numerical results regarding blocking probability suggest that wavelength assignment should favor the wavelength with the smallest amount of noise. The limits for the use a simple greedy algorithm are tested. Although the algorithm clearly fails when network is severely impaired by FWM , signi(cid:2)cant improvements are achieved for low and moderate levels of FWM .
