This paper proposes a new dynamic bandwidth and bandwidth allocation (DWBA) algorithm for energy saving in time and wavelength division multiplexing passive optical networks (TWDM PONs). Decreasing the number of active upstream wavelengths, the proposed algorithm not only saves power but also provides good efficiency for TWDM PON systems. Using simulations, we evaluate performance of the proposed algorithm under self-similar traffic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
