Abstract

The proposed adaptive power control based on the chaotic hurricane search optimization (A-CHSO) for elastic optical networks (EON)s dynamically and efficiently adjusts the power increasing (r₀) parameter taking into account the quality of transmission (QoT), which is measured by the optical performance monitors (OPM)s. For sake of comparison, three alternative power assignment methods are analyzed, the analytical gradient descent (GD), as well as two low-complexity methods, namely the egoistic power allocation (EPA) and the enough power allocation (EnPA). Numerical results demonstrate a promising performance-complexity trade-off for the A-CHSO regarding the GD, EPA and EnPA methods, as well as a substantial network margin reduction, energy efficiency increasing, and cost reduction. The A-CHSO has been proved to be an efficient power allocation (PA) method for operation in EONs, corroborating the dynamical and flexible aspects of the EONs.

弹性光网络自适应混沌飓风辅助有效功率分配

提出了一种基于混沌飓风搜索优化(A-CHSO)的弹性光网络自适应功率控制方法，该方法考虑了光性能监测仪测量的传输质量(QoT)，动态有效地调整了功率增量(r0)参数。为了比较，分析了三种可供选择的权力分配方法，即解析梯度下降法(GD)，以及两种低复杂度的权力分配方法，即利己主义权力分配法(EPA)和足够权力分配法(EnPA)。数值结果表明，在GD、EPA和EnPA方法中，a - chso具有良好的性能-复杂性权衡，并显著降低了网络裕度，提高了能源效率，降低了成本。A-CHSO已被证明是一种有效的永网运行功率分配方法，证实了永网的动态性和灵活性。
