“…The medium access control of 10G EPON is based on time division multiplexing access to control the ONUs' access to the upstream channel [16]. In this scheme, the OLT assigns a time slot called a grant (transmission window) for each ONU based on the polling mechanism; the ONU requests an amount of bandwidth, and the OLT decides the amount and assigns it.…”

Growing energy demands in the information and communication technology (ICT) sector have been recognized as a major challenge worldwide. Researchers have been actively working to address this challenge, and the major focus centers around improving the energy efficiency of access networks, which are known for consuming about three-quarters of the total network power. Among various access networks, the hybrid wireless-optical broadband access network (WOBAN), which combines a passive optical network (PON) with broadband wireless technology, is highly regarded for its enormous capacity, cost efficiency, and ease of deployment. To develop a green WOBAN, it is important to focus on reducing its power consumption, and in this work, we present an efficient resource management technique for WOBAN that reduces the power consumption of the optical line terminal (OLT) and optical network unit (ONU) by introducing sleep modes for the OLT and ONU, based on the service class and traffic load. Moreover, it considers the quality-of-service requirement of each service class. Simulation results confirm that our proposed solution can save a significant amount of power in the WOBAN network without sacrificing the quality of service of end applications.

“…With respect to medium access control (MAC) work on converged networks and in particular IP backhauling, existing literature mainly specifies the convergence of Ethernet-PONs (EPONs) with worldwide interoperability for microwave access (WiMAX) [18][19][20]. Convergences of LTE with next generation PONs (NGPONs) have only been discussed from the architectural point of view, investigating also physical layer impairments at both the optical and wireless domains [21,22].…”

This work was supported by the ACCORDANCE project, through the 7th ICT Framework ProgrammeA heterogeneous, optical/wireless dynamic bandwidth allocation framework is presented, exhibiting intelligent traffic queuing for practically controlling the quality-of-service (QoS) of mobile traffic, backhauled via orthogonal frequency division multiple access???PON (OFDMA-PON) networks. A converged data link layer is presented between long term evolution-advanced (LTE-A) and next-generation passive optical network (NGPON) topologies, extending beyond NGPON2. This is achieved by incorporating in a new protocol design, consistent mapping of LTE-A QCIs and OFDMA-PON queues. Novel inter-ONU algorithms have been developed, based on the distribution of weights to allocate subcarriers to both enhanced node B/optical network units (eNB/ONUs) and residential ONUs, sharing the same infrastructure. A weighted, intra-ONU scheduling mechanism is also introduced to control further the QoS across the network load. The inter and intra-ONU algorithms are both dynamic and adaptive, providing customized solutions to bandwidth allocation for different priority queues at different network traffic loads exhibiting practical fairness in bandwidth distribution. Therefore, middle and low priority packets are not unjustifiably deprived in favor of high priority packets at low network traffic loads. Still the protocol adaptability allows the high priority queues to automatically over perform when the traffic load has increased and the available bandwidth needs to be rationally redistributed. Computer simulations have confirmed that following the application of adaptive weights the fairness index of the new scheme (representing the achieved throughput for each queue), has improved across the traffic load to above 0.9. Packet delay reduction of more than 40ms has been recorded as a result for the low priority queues, while high priories still achieve sufficiently low packet delays in the range of 20 to 30m

“…In [1], the authors introduce a solution for the lack of distributed communication support by using a hybrid tree-ring architecture for LTE backhauling. The innovation of this research is the enabling of the stand alone distributed control of the LTE as well as the enabling of direct communication between ONUs.…”

“…With the increasing demand for bandwidth for mobile multimedia applications, it is estimated that the average household bandwidth requirement will jump to 1Gb/sec by 2020 [1]. In providing this increased bandwidth, network providers are interested in keeping their Operational Expenditure (OPEX) low and reaping the highest benefits from existing or new infrastructure with minimum capital expenditure (CAPEX).…”

With increasing demand on bandwidth and mobile media applications, pressures upon network providers to provide more bandwidth to users and better Quality of Service (QoS) is increasing. For example, High Definition (HD) Video on Demand (VoD) streaming requires an average of 10 Mb/sec per user. Meeting these needs through the use of fiber optic networks to backhaul the traffic is essential, since fiber optic networks provide bandwidth measured at a rate of Gb/sec. However, most mobility management protocols are not built to handle fiber optic networks. Ethernet Passive Optical Network (EPON) is the dominant fiber optic network in the market due to its simplicity and cost of deployment. This paper describes how EPON can be used effectively to meet the need for increased bandwidth and handoff demands of mobile terminals. This paper studies Proxy Mobile IPv6 (PMIPv6) as the dominant network-based localized mobility management (Netlmm) protocol. Vehicle Ad Hoc Network (VANET) amplifies the handoff problems due to its unique characteristics. Hence, the issues and challenges of using the EPON network with PMIPv6 will be analyzed. Finally, recommendations will be established to optimize the usage of EPON with local mobility management protocols. This research shows by means of analysis the need for new protocols to support fast mobile IP optimization and then propose a solution that is tailored for EPON and analyze the proposed solution mathematically.
