| Popis: | In this paper, the novel shortest energy consumption Routing Spectrum Assignment (SEC-RSA) algorithm based on Distance Adaptive Modulation (DAM) is introduced. 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, 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 enhances. The results show that the energy consumption decreases when SEC-RSA algorithm is used in comparison with traditional ones. Moreover, energy consumption decreases as the order of modulation increases. The outcomes additionally figure out that energy consumption decrease when block connections are considered. |
