    Models for Evaluating Power Saving Techniques in Flexible Optical Access Networks
    (IEEE, 2018) Garg, Sukriti
    Increased use of power in telecommunication networks has not only increased the cost of operation but also increased the carbon footprint and the environmental hazards. In this paper, we propose models for evaluating power saving techniques in flexible passive optical access networks. In addition, the power model of their sleep modes are proposed and are extended to analyse the power saving potentials of state-of-art dynamic bandwidth allocation (DBA) algorithms like sleep mode aware (SMA) and hybrid sleep mode aware (HSMA).

    Novel Dynamic Bandwidth and Wavelength Allocation Algorithm for Energy Efficiency in TWDM-PON
    (IEEE, 2019) Garg, Sukriti
    In this paper, we propose a novel dynamic bandwidth and wavelength allocation (DBWA) algorithm that makes use of bin-packing approach resulting in the improved energy efficiency for time and wavelength division multiplexed passive optical networks (TWDM-PONs). Simulation results show that this novel DBWA algorithm not only improves the energy efficiency of TWDM-PON but also its delay performance in comparison to the state-of-art DBWA algorithm.
