Abstract :
Doze and sleep mechanisms are the most common energy-saving solution in GPON networks. Sleep duration is the critical value in the energy-saving domain, and it will affect the QoS metrics with inappropriate value. In this paper, a new energy-saving mechanism is proposed using an optimal point based on gradient descent that calculates sleep duration and keeps QoS metrics acceptable. The historical value of average delay and packet, drop ratio, ONU buffer, and bandwidth request parameters are used as input, and the sleep duration value is calculated. The simulation results show that the proposed method saves up to 17% energy in GPON and keeps the network’s QoS in an acceptable domain.
