“…The energy consumption of these technologies appears to be a daunting challenge. It is estimated that the access network is responsible for the 70% of the overall energy consumption of the communication network [1]. Furthermore, an access network comprises of a perpetually growing number of active devices, a fact suggesting that the energy consumption will continue to rise during the next decades [1].…”

Undoubtedly, energy consumption in communication networks poses a significant threat to the environmental stability. Access networks contribute to this consumption by being composed of numerous energy inefficient devices and network equipment. Passive Optical Networks (PONs), one of the most promising candidates in the field of access networking, should avoid this bottleneck in the backhaul power consumption by lowering the energy use of the optical devices. In this paper, we move towards that direction by introducing an energy efficient power management scheme that encompasses two major goals: a) to reduce the energy consumption by allowing the optical devices to enter the sleep mode longer, and b) to concurrently maintain the network performance. To this end, we focus on the energy consumed by the optical network units (ONUs). The intelligence of the ONUs is stimulated by enhancing the decision making in determining the duration of the sleep period with learning from experience mechanism. Learning automata (LAs) are charged to address this challenge. The evaluation of the proposed enhanced power management scheme reveals considerable improvements in terms of energy savings, while at the same time the network performance remains in high levels.

“…Considering a volume of 142 million fibre-to-the-home subscribers [2], any efficiency improvement of the CPE will have a significant impact on the total energy consumption of the network. Also, PON being the most energy efficient of all fixed access technologies [3], is the best starting point for advanced energy optimizations. Finally, the room for optimization exists because all standard TDM PON protocols are inherently energy inefficient as a result of the standardimposed requirement for translation from the physically broadcast to the logically unicast packet traffic to be performed by the media access control (MAC) protocol layer of the receiving PON CPE.…”

A novel, low energy protocol for passive optical networks (PON), featuring bit-interleaving of downstream traffic, is described. The bit-interleaving protocol enables decimation of the received frame, which eliminates the processing overhead associated with unrelated traffic by customer premises equipment (CPE), while preserving the flexibility of downstream bandwidth allocation. Measurement results obtained from a bit-interleaving PON prototype at the line rate of 10 Gb/s indicate a reduction of CPE dynamic power consumption by a factor of 30, with respect to the power of a standard PON CPE at the same line rate. Additionally, a significant reduction in CPE hardware complexity, with respect to that of a standard PON CPE, is achieved.

“…It has been estimated that access networks consume around 70 % of overall telecommunications network energy expenditures and this percentage is expected to grow in the next decade [5,6]. An important part of the energy consumption is given by the wireless part of the access and it has been estimated that the base stations represent 80% of the total wireless consumption [7].…”

Energy Savings in Wireless Mesh Networks in a Time-Variable Context

Energy consumption of communication systems is becoming a fundamental issue and, among all the sectors, wireless access networks are largely responsible for the increase in consumption. In addition to the access segment, wireless technologies are also gaining popularity for the backhaul infrastructure of cellular systems mainly due to their cost and easy deployment. In this context, Wireless Mesh Networks (WMN) are commonly considered the most suitable architecture because of their versatility that allows flexible configurations. In this paper we combine the flexibility of WMN with the need for energy consumption reduction by presenting an optimization framework for network management that takes into account the trade off between the network energy needs and the daily variations of the demand. A resolution approach and a thorough discussion on the details related to WMN energy management are also presented.
