“…This includes initiatives pushing for rapid power up/down methods and energy efficient sleep/idle modes for networking equipment (from access equipment to core equipment). Furthermore, noting the diurnal nature of communication network traffic, proposals for powering down parts of a network infrastructure during low load periods to save power and OPEX costs have appeared in the literature [3]. This literature has focused on saving energy without regard for the effects on resilience, which will be longer restoration times, less fault tolerance and lower levels of availability.…”

This paper highlights the complexity and challenges of providing reliable services in the evolving communications infrastructure. The hurdles in providing end-to-end availability guarantees are discussed and research problems identified. Avenues for overcoming some of the challenges examined are presented. This includes the use of a highly available network spine embedded in a physical network together with efficient crosslayer mapping to offer survivability and differentiation of traffic into classes of resilience.

Abstract-Internet infrastructure energy consumption is a major topic of research nowadays due to environmental and economical concerns. Therefore, it is increasingly important new solutions that decrease energy consumption, but without impairing network throughput and costs. Hence, it is important to survey and categorize current techniques, not only applicable to IP networks, but that can also be potentially useful for the future Internet architectures, such as Publish-Subscribe architectures. Therefore, to achieve such goals this paper presents a survey on energy efficient architectures and functional mechanisms (such as energy adaptive routing) for the current and future Internet. The main goals are: to provide an overview of the issues of the current Internet architecture; to identify the contribution of the different proposals for the future Internet architecture; and to discuss energy saving techniques which improve Internet energy efficiency.Index Terms-Energy, future internet architectures, energy efficient routing, traffic engineering, survey.

“…However, the exponential increase in data traffic is accompanied by a rapid increase in energy and environmental costs [2]. Interestingly, the small cell architecture is not only energy efficiency but the low transmit power required also allows for the employment of renewable energy sources at the basestations (BSs).…”

Abstract-This work examines offline and online power control policies for efficient usage of renewable energy in the downlink of a multi-antenna wireless system. Two multiuser beamforming schemes are considered, namely, channel inversion (CI) and maximal ratio transmit (MRT) beamforming schemes. Power control policies are derived for both schemes, respectively, with the goal of maximizing the sum throughput by a deadline subject to energy causality and battery storage constraints. With CI beamforming, the power control problem can be formulated as a convex optimization problem, whose solution can be obtained using the directional water-filling algorithm. With MRT beamforming, the power control problem becomes non-convex, due to interference between the signals intended for different users, and, thus, is difficult to solve exactly. However, an efficient solution can be obtained by performing successive approximation into a sequence of geometric programming problems, i.e., by employing the condensation method. Offline power control policies are first derived assuming non-causal knowledge of the energy arrival and channel coefficients over time. Online power control policies are then proposed based on observations gained from the offline policy. The performance of the proposed schemes are demonstrated through numerical simulations.
