“…The proposed DWBA scheme employs the Water-Filling technique and an advanced intra-ONU scheduling discipline but it requires the ONUs capability to transmit over multiple wavelengths simultaneously, using a bank of fixed transceivers or tunable lasers, a fact which raises the overall cost dramatically. A first-fit DBWA algorithm providing a low average packet delay and catering the frame resequensing problem for NG-PONs is presented in [22]. The proposed solution improves the bandwidth utilization by reducing the excessive use of guard time as compared with other schemes but it also suffers from the high cost demand of the ONU multichannel transmission capability.…”

“…which results to α = 1.4 given that H = 0.8. For the ON period the shape parameter α ON is set to 1.4 according to (22) and the location parameter b ON , which adjusts the lower limit of a burst is set to 1 since the smallest burst contains only 1 packet.

Communication networks for healthcare environments support various application types and should be capable of providing them with the required Quality of Service (QoS) in terms of reliable data delivery, considerable data rate and low latency. The introduction of Tactile Internet (TI) healthcare applications is expected to upgrade the level of provided services to patients. The requirements of these applications are very stringent and a major requirement is that the existing network infrastructure must support them. Passive Optical Networks (PONs) have been proposed as an ideal candidate to support such demanding environments. One of the major challenges of such networks, which significantly affects the provided QoS, is the effective resource allocation in both the time and the wavelength domains. The existing resource allocation algorithms for PONs were designed without considering the stringent requirements of TI applications thus making PON support for TI inefficient. In this paper, a new double per priority queue dynamic wavelength and bandwidth allocation algorithm is presented. This algorithm allocates the network resources efficiently and fairly using several techniques, in order to meet the QoS demands of Tactile and other types of healthcare applications. Extensive simulation results indicate the effectiveness of the proposed algorithm to provide the required QoS for medical applications under various simulation scenarios whereas other well-known schemes are shown to lack such support.

“…In [21], the authors successfully implemented the DBA algorithm for fog services and implemented a single line for ONU that resulted in a cost-effective and energy-saving model. Reference [22] dealt with the average packet delay and servicing frame sequencing issues to service DBA for EPON devices, particularly upstream wavelength channels. In [23], the authors developed a model and DBA scheme to schedule transmission with eradicated delays, and power consumption occurred when the ONU transmitted new wavelengths.…”

The next-generation Ethernet passive optical network (NG-EPON) is basically classified into two architectures on the basis of the wavelength sharing by the optical network units (ONUs). The single scheduling domain (SSD) and multi-scheduling domain (MSD) EPON are the two different design architectures for NG-EPON. A vital task in NG-EPON is to design dynamic wavelength bandwidth allocation (DWBA) algorithms that can meet the future demands of the network subscribers. A number of DWBA algorithms have been designed for time and wavelength division multiplex (TWDM) EPON. The existing DWBA algorithms for TWDM-EPON could be used in MSD-EPON by making necessary parametric changes. The design and implementation of new DWBA algorithms for MSD-EPON are still required specifically. In this paper, we have proposed a quality of service (QoS)-based DWBA algorithm for NG-EPON. We have comparatively analyzed our proposed DWBA with the existing algorithms like earlier finished time (EFT), weighted bipartite matching (WBM), and earlier finished time with void filling (EFT-VF). The results show that our proposed DWBA algorithm performs better as compared to EFT, WBM, and EFT-VF on the basis of average packet delay and average completion time for NG-EPON.
