Energy-efficient dynamic wavelength and bandwidth allocation algorithm for TWDM-PONs with tunable VCSEL ONUs
A dynamic wavelength and bandwidth allocation algorithm using tunable 10G-SC-VCSEL
ONUs is proposed for TWDM-PONs. The algorithm optimizes the number of active
wavelengths under a given delay constraint and incorporates sleep and doze operations for
improved energy-efficiency.

Offline energy-efficient dynamic wavelength and bandwidth allocation algorithm for TWDM-PONs
We previously proposed and numerically analyzed a theoretical framework of an energy-
efficient offline dynamic wavelength and bandwidth allocation (DWBA) algorithm designed
for a delay-constrained time and wavelength division multiplexed passive optical network
(TWDM-PON). This DWBA algorithm exploits the tunability and the sleep/doze capabilities of
a 10 Gbps vertical-cavity surface-emitting optical network unit (10G-VCSEL-ONU) to improve
the energy-savings at the OLT and the ONUs, respectively. In this work, using simulation …
