Cognitive zone-based spectrum assignment algorithm for elastic optical networks

In this work, we present the Cognitive Zone-Based spectrum assignment algorithm (CZB). Our algorithm is capable of observing the network traffic and acquiring information regarding the network services, thus using it to calibrate the division of the spectrum into partitions. To achieve this, the CZB algorithm uses an upgraded version of the Static Zone-Based spectrum assignment algorithm. Our results show that CZB algorithm can indeed achieve its objective, and even improve the fairness under certain conditions. Simulations show that CZB algorithms can achieve up to 10 times better fairness under certain conditions when compared to the Spectrum Sharing FirstFit algorithm.
