Sleep-aware wavelength and bandwidth assignment scheme for TWDM PON. [PDF]
Opt Quantum Electron, 2021 The energy efficiency and delay performance of PON are two inversely related phenomena. Higher sleep time of the Optical Network Units (ONUs) results in higher upstream (US) delays due to increased traffic queues during the ONU Asleep state. Although an efficient dynamic bandwidth and wavelength assignment (DWBA) scheme can decrease US delays by ...
