“…All these techniques are especially important if the trend of shrinking cell sizes is to continue in order to support the increased datarate requirements of today's and tomorrow's mobile communication needs. Clearly the same two paths (in terms of hardware and software advances) are also being considered in the case of mobile phones [39]. However significant research and development has already been conducted in the past for reducing the energy waste of the inherently battery constraint mobile devices and thus little additional gains are expected from such mechanisms.…”

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.

“…Two good overviews of the past and future research directions in the field of power management for mobile networks are given in [6,7]. In [6] the mobile device and battery capacity evolutions, multiaccess nature of modern mobile devices and the respective implications for power management are described, as well as a proposal of an information-centric approach to networking, which allows audio/video streaming to be transformed from an energy-heavy network service to a lightweight one.…”

“…In [6] the mobile device and battery capacity evolutions, multiaccess nature of modern mobile devices and the respective implications for power management are described, as well as a proposal of an information-centric approach to networking, which allows audio/video streaming to be transformed from an energy-heavy network service to a lightweight one. However, the last would require an adoption of a new networking paradigm and a change in the way the information is distributed to its intended recipients.…”

a b s t r a c tThis paper presents an analysis of the power consumption of video data transmission with constant bit rate over 3G mobile wireless networks. The work includes the description of the radio resource control transition state machine in 3G networks, followed by a detailed power consumption analysis and measurements of the radio link power consumption. Based on this description and analysis, we propose our power consumption model. The power model was evaluated on a smartphone Nokia N900, which follows 3GPP Release 5 and 6 supporting HSDPA/HSUPA data bearers. We also propose a method for parameter selection for the 3GPP transition state machine that allows to decrease power consumption on a mobile device taking signaling traffic, buffer size and latency restrictions into account. Furthermore, we discuss the gain in power consumption vs. PSNR for transmitted video and show the possibility of performing power consumption management based on the requirements for the video quality.

“…Although the subjacent technologies are continuously improving to accommodate the increased demand (the faster rollout of High Speed Packet Access [HSPA] and Long Term Evolution [LTE] when compared to 3G deployments are examples of such an evolution), there are still several gaps which need to be addressed. In parallel to the advances on the subjacent technologies and their capacity, the consequences brought about by the upcoming Future Internet network architecture proposals are poised to lead to changes in the current communications paradigm [1]. A paradigm shift will affect the way networks and services (particularly within mobile environments) are designed, dimensioned, deployed, and managed, especially when we consider that resources are to be jointly shared and managed.…”
