Abstract
A novel wavelength and bandwidth allocation algorithm in WDM-EPON is proposed to provide subscriber differentiation by ensuring guaranteed bandwidth levels in the upstream direction. Contrary to previous schemes, the new algorithm is designed to save cost at both ends of the network, especially at the users’ side, as it restricts the number of upstream wavelengths which can be used by them. Simulation results show that ShaWaG achieves better performance than other bandwidth allocation algorithms in WDM-EPONs but simultaneously it requires lower number of upstream wavelengths. The novel algorithm makes fairer bandwidth distribution than those methods as it ensures efficiently a minimum guaranteed bandwidth to every subscriber for a larger number of ONUs when compared to existing methods.
