Novel Dynamic Bandwidth and Wavelength Allocation Algorithm for Energy Efficiency in TWDM-PON

In this paper, we propose a novel dynamic bandwidth and wavelength allocation (DBWA) algorithm that makes use of bin-packing approach resulting in the improved energy efficiency for time and wavelength division multiplexed passive optical networks (TWDM-PONs). Simulation results show that this novel DBWA algorithm not only improves the energy efficiency of TWDM-PON but also its delay performance in comparison to the state-of-art DBWA algorithm.
