“…The authors in [30] proposed a sleep aware dynamic bandwidth allocation (SDBA) scheme to maximize energy efficiency while guaranteeing the QoS requirements on both upstream and downstream transmissions. Based on the strictest QoS requirements of all the traffic, the SDBA maximizes the polling cycle length to extend the ONU sleep time.…”

“…The OLT determines the presence or absence of downstream traffic by monitoring the average frame interval. Based on the SPW regime, the authors in [14] propose a Sleep-aware Dynamic Bandwidth Allocation (SDBA) algorithm that maximizes the ONU energy-saving while guaranteeing QoS requirements. Unlike other proposals, the SDBA algorithm is experimentally evaluated in an FPGA-based testbed.…”

One of the main challenges of Passive Optical Networks (PONs) is the resource (bandwidth and wavelength) management. Since it has been shown that access networks consume a significant part of the overall energy of the telecom networks, the resource management schemes should also consider energy minimization strategies. To sustain the increased bandwidth demand of emerging applications in the access section of the network, it is expected that next generation optical access networks will adopt the wavelength division/time division multiplexing (WDM/TDM) technique to increase PONs capacity. Compared with traditional PONs, the architecture of a WDM/TDM-PON requires more transceivers/receivers, hence they are expected to consume more energy. In this paper, we focus on the energy minimization in WDM/TDM-PONs and we propose an energy-efficient Dynamic Bandwidth and Wavelength Allocation mechanism whose objective is to turn off, whenever possible, the unnecessary upstream traffic receivers at the Optical Line Terminal (OLT). We evaluate our mechanism in different scenarios and show that the proper use of upstream channels leads to relevant energy savings. Our proposed energy-saving mechanism is able to save energy at the OLT while maintaining the introduced penalties in terms of packet delay and cycle time within an acceptable range. We might highlight the benefits of our proposal as a mechanism that maximizes the channel utilization. Detailed implementation of the proposed algorithm is presented, and simulation results
