“…Hossen et al [6,7] have proposed a new DBA algorithm for the multi-OLT PON-based hybrid networks. However, those papers have considered a network structure where a single uplink wavelength is used and every ONU is connected to a single service provider.…”

“…In the multi-OLT PON-based hybrid networks, proposed by Hossen et al [6,7], each ONU connects to the users of a single service provider that means no need to share a single ONU by the multiple service providers. However, in the PON-based OAN each ONU should be shared by all the service providers.…”

“…In [2][3][4], the authors have proposed adaptive DBA algorithms for the PON based hybrid fiber to the home (FTTH) and wireless sensor networks (WSNs). The main concern of these adaptive DBA algorithms is to mitigate the problems associated for converging data packets of both the FTTH and WSNs in a single PON having different packet lengths and data rates.…”

“…That is why, in the time division multiple access (TDMA) PON, a dynamic bandwidth allocation (DBA) algorithm plays a significant role for providing efficient and fair utilization of the upstream channel bandwidth. The DBA is a technique by which bandwidth in a single channel can be allocated to the ONUs of a PON on the basis of their demands [1][2][3][4][5][6]. One of the main advantages of the DBA algorithms is that it can reduce the bandwidth wastage by allocating smaller transmission windows if there is lightly loaded ONUs.…”

Passive optical network (PON) is a highly dynamic access network that effectively converge several service providers. In a time cycle, some optical network units (ONUs) of PON may miss the usual polling instant called unstable ONUs. According to the existing early dynamic bandwidth allocation (E-DBA) algorithm, once an ONU miss the usual polling instant it needs to be waited until the end of transmissions from the entire stable ONUs. So the unstable ONUs suffers from more waiting time than the stable ONUs. This paper proposes a new DBA algorithm called modified E-DBA (ME-DBA) algorithm, for reduction of waiting times of the unstable ONUs. In the proposed algorithm, total ONUs are divided into several small groups. The data packets from all the stable ONUs of a group are transmitted 1 st and then the data packets from the unstable ONUs of that group are transmitted. We have analyzed and compared the performance of the proposed ME-DBA algorithm with the existing E-DBA algorithm in terms of the delay and waiting time of the unstable ONUs by simulations. The simulation results show that the proposed algorithm provides lower packet delay and waiting time for the unstable ONUs than that of the existing E-DBA algorithm.

“…In [24], a hybrid approach combining genetic algorithm and tabu search techniques was proposed to determine the optimal placement of optical network units (ONUs)-the CPE of a PON-in hybrid PON-wireless sensor network (WSN) based networks, whereby the ONUs' high power and processing capabilities were used to serve as cluster heads with the objective to minimize the wireless sensors' energy consumption. In [25], a DBA algorithm was developed for a hybrid PON-WSN network, where ONUs are connected to FTTH terminals or to WSN cluster heads for remote monitoring systems in a ubiquitous city, e.g., medical sensors in a hospital monitoring system. The integration of solar-powered wireless sensors and low-power fiber optic sensors into a PON was experimentally demonstrated in [26].…”

The primary design goal of (r)evolutionary NG-PON1&2 was the provisioning of an ever increasing capacity to cope with video-dominated traffic and handle the explosion of mobile data traffic by means of offloading. Recently, however, questions on the future of "post NG-PON2" have surfaced whether to shift its research focus to business and operation related aspects and move access technology into a substantially different direction than continued capacity upgrades. In fact, recent studies indicate that ultimately the major factor limiting the performance of 4G mobile networks is latency rather than capacity of the backhaul. In this paper, we review recently proposed low-latency techniques for NG-PONs that require architectural modifications at the remote node or distribution fiber level and highlight advanced network coding and real-time polling based low-latency techniques that can be implemented in software, enable NG-PONs to carry higher traffic loads and thereby extend their lifetime, and maintain the passive nature of existent optical distribution networks. Furthermore, we elaborate on emerging trends and open challenges for future post NG-PON2 research. To better understand their true potential, we put them into a wider non-technical and historical perspective leading up to a sustainable Third Industrial Revolution (TIR) economy and its underlying Energy Internet.
