Energy Consumption Improvement based on Distance Adaptive Modulation in Optical Elastic Network

EasyChair Preprint 579

Abstract

In this paper, a novel algorithm based on distance adaptive modulation routing spectrum assignment is presented. The shortest energy consumption Routing Spectrum Assignment (SEC-RSA) algorithm was developed, based on Distance Adaptive Modulation (DAM). According to the distance between source and destination, for a determinate lightpath, the modulation pattern is modified. The energy consumption is computed for the k-shortest path and, then, the one with lowest energy consumption is adopted. The algorithm can dynamically commute to another modulation as the connections requests or the numbers of lightpath between source and destination increases. The results show that the energy consumption decreases when SEC-RSA algorithm is used in comparison with traditional ones. Energy consumption decreases as the order of modulation increases. The results also figure out that energy consumption decrease when block connections are considered.
