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.

“…Highpriority traffic (i.e., EF traffic) is modeled using the Poisson distribution with a fixed packet size (70 bytes) [7]. This model generates the high burst AF and BE traffic with a hurst parameter of 0.8 [27][28][29]. The packet size is uniformly distributed between 64 and 1518 bytes.…”

“…The ONU buffer size is set to 5 Mb, and the distance between the OLT and the ONUs is uniform over the range from 10 to 20 km. Selfsimilarity and long-range dependence is used as the network traffic model for AF and BE [26][27][28][29]. High-priority traffic (i.e., EF traffic) is modeled using the Poisson distribution with a fixed packet size (70 bytes).…”

Ethernet passive optical network (EPON) is a broadband access time-division multiplexing passive optical network technology which can be referred to as green network, as it has less power consumption compared with other networks. The optical network unit (ONU) is the best candidate to implement energy-saving adjustments in EPON. Turning off the ONU transmitter (Tx)/receiver (Rx) for substantial time is a common method to achieve the energy saving. However, setting overlong sleep duration decreases the QoS, while short sleep duration increases the ONU power consumption. The challenging issue is how to balance the trade-off between achieving energy saving and guaranteeing QoS. In this paper, we introduce an enhanced EPON architecture and a QoS-aware energy-saving mechanism to reduce ONU energy consumption and guarantee an overall QoS metric based on the ITU-T standards requirements. To achieve the energy saving in the upstream/downstream direction, two sleep durations are defined for the ONU's Tx/Rx to generate four ONU modes including active, transmission, doze, and sleep. Simulation results show that the proposed scheme B I-Shyan Hwang improves the energy efficiency 44 % in average to fulfill the QoS metrics in terms of packet loss, delay and jitter, and the buffer requirement.
