Optimization of Energy Consumption and Bandwidth used in Elastic Optical Network

This paper introduces a novel strategy to improve elastic optical network performance through ECOAM algorithm. When a demand arrives, K-shortest paths are selected and the quality of transmission requirement is investigated. Whether it is accomplished, the appropriate modulation format is adaptively allocated to every lightpath according to the target OSNR. The required bandwidth varies according to the lightpath length differently from the literature where the bandwidth is fixed or predefined in a range. Energy consumption of the K-shortest is computed and the lowest is selected. Numerical results have been compared with SP and MH algorithm. Analytical comparison demonstrated that energy consumption is saved up to 17% while the bandwidth used is reduced up to 33%.
