“…There are different mechanisms available to achieve energy efficiency at front end and back end sub networks. In most of the energy saving approaches used for front and back end sub-networks, the device will turn off their transceiver either fully or partially in idle state [4]. Proposed work is focused on reduction in energy consumption of front end WLAN sub-network by rate adaptation algorithm along with power saving mode (PSM).…”

“…It is shown in [6] that the GPON digital (layer-2) processing and optical physical interface, combined with the Ethernet local area network interface for the in-home connectivity, consumes about 54% of the total in-home communication network power. The ONU and WAP are typically connected using a coaxial cable or an Ethernet cable [6]. In the case of today's office buildings, there is typically a main distribution frame (MDF), which is connected to the access network with a high-throughput optical Ethernet link, and several intermediate distribution frames (IDFs) serving the WAPs and user equipment via copper Ethernet links [6].…”

This paper proposes the cascaded bitinterleaved optical network protocol, an energy-efficient solution aiming at low power consumption in converged optical access/in-building networks while providing high data rates to end users, and a novel network architecture for optical access/in-building networks. In the proposed network architecture, optical-electrical-optical (OEO) regeneration is employed at the interface between access and in-building networks. The downstream frames are generated in the central office using a two-stage bitinterleaving scheme. In the downstream direction, the network nodes only process the data destined for them at a lower clock rate than that of the aggregate passive optical network (PON). In the upstream direction, no word alignment or decoding is performed in the intermediate nodes.Simulation and experimental results show that significant reduction in the power consumption of access/in-building networks can be achieved when the proposed cascaded bit-interleaved protocol is employed in conjunction with the proposed network architecture.

Energy efficiency is rapidly becoming an important requirement for modern networks. In this paper, we discuss the physical limits to the power consumption of wireless and optical transmission. We show that there is an optimum cell size that results in the least power consumption in optical/wireless in-building networks and explain why. We then discuss the principles that govern the design of in-building Radio-over-Fiber (RoF) distribution networks. We use theoretical models to analyze the impact of key design factors on the energy consumption of point-to-point RoF links and how their adverse effects can be mitigated. Finally, we compare the energy consumption of several key in-building optical/wireless architectures based on several different RoF technologies, and demonstrate that centralized architectures based on RoF links can be substantially more energy efficient than baseband-over-fiber (BoF) architectures in network capacity-limited scenarios, when designed properly. Our findings also show that RoF-based architectures are energy efficient for cell sizes less than 10m. Keywords: energy-efficiency, Radio-over-Fiber, in-building networks. INTRODUCTIONThe need to reduce the carbon footprint of telecommunication networks is widely recognized [1,2]. Recent studies reveal that the power consumption of data centers is comparable to that of in-building networks (residential and office) due to the large number of buildings and the spreading Internet literacy of their users [1]. By year 2017, 55% of all IP traffic will originate from wireless and mobile devices [3]. Furthermore, two-thirds of all IP traffic will be consumer traffic originating from households, universities and Internet cafes. This means that the main source of extensive wireless Internet traffic will be from in-building IT networks. Thus, it is important to explore ways for reducing the energy consumption of office and residential building networks. Due to the large number of in-building networks, even a small decrease in the energy consumption in each of the individual networks would lead to a significant decrease in the overall energy consumption.Wireless communications enables mobile access to the Internet; however, it has limited bandwidth and suffers from inherent energy loss due to its broadcast nature rendering it fundamentally energy inefficient compared to wired transmission links such as optical links. In contrast, optical links offer very high-speed access to the Internet with low energy loss, but cannot offer user mobility. Consequently, optical/wireless convergence is seen as an ideal candidate for increasing the network bandwidth, decreasing its energy consumption and offering end-user mobility. Radio-over-Fiber (RoF) is a promising technology for the implementation of seamless and energy-efficient optical/wireless networks [2].In this paper, we study the physical limits of both optical and wireless transmission links and their impact on the power consumption of the network as a whole. We show that there is an optimum cell size for an op...
