“…N T RX and η P A denote the number of transceiver and power efficiency of the amplifier, respectively. It was further shown in some previous works (e.g., State-Of-The-Art (SotA) [17], Market 2014 [19], Improved DTX [20] and Future Model [21]) that the BS power consumption or supply can be approximated by linear function of the transmission power. In this work, we concentrate on the Future Model, and it is summarised in Equation (11) by:…”

Abstract-Energy-efficient transmission is fast becoming a critical factor in designing future mobile broadband cellular communication systems. This research work examines the constraints with regard to the achievable throughput and energy efficiency that can be attained on the use of precoding-based massive MIMO systems, bearing in mind the effect of some key performance impacting parameters. We first introduced an absolute energy efficiency-based model to evaluate the deep-down relationship among the packet length, the Bit error rate (BER) and throughput. Then, by means of simulation with cyclic coordinated search algorithm, optimal achievable throughput and energy efficiency performance have been shown and demonstrated for variable capacity of users and number of transmission antennas. This work is expected to be of enormous importance to practical system design on the use of massive MIMO antenna technology for data throughput and energy efficiency maximization in future 5G systems.

“…However, both AS and EST allow for dynamic variation in the delivered and buffered data volume and this flexibility is capitalized here to optimize both the delivery volume and the buffer size in order to achieve energy efficiency gains while ensuring uninterrupted content playback. Furthermore, we show that instead of simply fixing the buffered content duration to a fixed value 1 , an optimized buffer size can result in substantial energy efficiency gains. Optimized buffering is also implemented for EST.…”

“…Cellular networking solutions are expected to provide a significant boost in meeting the requirements for higher datarates and increased traffic demand while maintaining and even reducing the communication energy expenditure [1]. Evidently, the interest has shifted towards the deployment of heterogeneous access technologies that will allow not only an increase in aggregated throughput but further alleviate the burden of heavy loaded cells by offloading traffic over Wireless Local Area Networks (WLANs), either through WiFi access points or femtocells or co-existence of both.…”

Energy efficient mobile video streaming using mobility

Abstract-Undeniably the support of data services over the wireless Internet is becoming increasingly challenging with the plethora of different characteristic requirements of each service type. Evidently, about half of the data traffic shifted across the Internet to date consists of multimedia content such as video clips or music files that necessitate stringent real-time constraints in playback and for which increasing volumes of data should be shifted with the introduction of higher quality content.This work recasts the problem of multimedia content delivery in the mobile Internet. We propose an optimization framework with the major tenet being that real-time playback constraints can be satisfied while at the same time enabling controlled delay tolerance in packet transmission by capitalizing on prefetching and data buffering. More specifically two strategies are proposed amenable for real time implementation that utilize the inherent delay tolerance of popular applications based on different flavours of HTTP streaming. The proposed mechanisms have the potential of achieving many-fold energy efficiency gains at no cost on the perceived user experience.

Abstract:Energy efficiency is an important criterion in the design of next generation networks for both economic and environmental concerns. This paper presents an energy-efficient router that is able to dynamically adapt its routing capability in response to real-time traffic load, achieving energy proportional routing. The NetFPGA reference router, which operates at one of two frequencies (125 MHz or 62.5 MHz), requires a board reset to switch frequencies. We have modified the reference router to allow dynamic switching among five operating frequencies. Experiments with real traces indicate that, compared to the reference router, a 10% power reduction can be achieved through dynamic frequency scaling. When the router is further modified to support green traffic engineering and Ethernet port shut-down, power consumption can be reduced by 46% while maintaining the required quality of service. This allows the router to meet the instantaneous performance requirements while minimizing power dissipation. Similar results can be expected when these general power-saving principles are applied in future commercial routers.
