“…Dynamic bandwidth allocation is also utilized in [29] that prioritize flows of packets to improve TCP's performance. Survivability is considered in [30] for energy efficient FiWi networks that enhances reliable and robust services under increased traffic conditions. Performance-enhancing network coding techniques are utilized and integrated in order to increase the throughput and decrease the delay of FiWi access networks for unicast and multicast traffic conditions [31].…”

“…In summary, the previous works [15][16][17][18][19][20][21][22] mostly focus on the energy savings in the WDM/TDM PON architectures and [22][23][24][25][26][27][28][29][30][31][32] proposes energy efficient studies in the FiWi networks by combining ONU sleep mechanisms with delay control schemes. It will be promising to introduce different CRMs that could enhance reconfigurable and service on demand converged access network with cost effective and energy efficient characteristics.…”

Abstract-Current Gigabit-class passive optical networks (PONs) evolve into next-generation PONs, whereby high-speed Gb/s time division multiplexing (TDM) and long-reach wavelength-broadcasting/routing wavelength division multiplexing (WDM) PONs are promising near-term candidates. On the other hand, next-generation wireless local area networks (WLANs) based on frame aggregation techniques will leverage physical-layer enhancements, giving rise to Gigabit-class very high throughput (VHT) WLANs. In this paper, we develop an analytical framework for evaluating the capacity and delay performance of a wide range of routing algorithms in converged fiber-wireless (FiWi) broadband access networks based on different next-generation PONs and a Gigabit-class multiradio multichannel WLAN-mesh front end. Our framework is very flexible and incorporates arbitrary frame size distributions, traffic matrices, optical/wireless propagation delays, data rates, and fiber faults. We verify the accuracy of our probabilistic analysis by means of simulation for the wireless and wireless-optical-wireless operation modes of various FiWi network architectures under peer-to-peer, upstream, uniform, and nonuniform traffic scenarios. The results indicate that our proposed optimized FiWi routing algorithm (OFRA) outperforms minimum (wireless) hop and delay routing in terms of throughput for balanced and unbalanced traffic loads, at the expense of a slightly increased mean delay at small to medium traffic loads.Index Terms-Availability, fiber-wireless (FiWi) access networks, frame aggregation, integrated routing algorithms, next-generation passive optical networks (PONs), very high throughput wireless local area network (VHT WLAN).

“…Thus, the development of FiWi also needs to take into account the energy saving issue. Lincong Zhang and Jiangzi Yang discussed in their paper [4] about Green Survivability factor in Fi-Wi network by using Energy saving Algorithm based on Sleeping Low-load ONUs (EASLO). They design a novel ONU architecture which is working with three efficient functionalities.…”

ABSTRACT:In recent years there is an explosive growth towards broadband access technologies which basically require higher bandwidth, better flexibility and lower cost access network and enable users to access internet in an "Anytime Anywhere" fashion. So Fiber-Wireless (Fi-Wi) is efficiently combination of both optical network and wireless network which can change the future of broadband services. By integrating the technical merits of both the technologies Fi-Wi broadband access network is proposed which provides an internet services with high speed at lower cost. The key issue in Fi-Wi network is the placement of optical network unit (ONU) since it provides interface between the optical and wireless network in order to making cost -efficient network different algorithms proposed. In this paper we go through different algorithms and analyzing which one is efficient for ONU placement in network.
