Download or read book Assessing the Energy Consumption of Smartphone Applications written by Mustafa M. Abousaleh and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile devices are increasingly becoming essential in people's lives. The advancement in technology and mobility factor are allowing users to utilize mobile devices for communication, entertainment, financial planning, fitness tracking, etc. As a result, mobile applications are also becoming important factors contributing to user utility. However, battery capacity is the limiting factor impacting the quality of user experience. Hence, it is imperative to understand how much energy impact do mobile apps have on the system relative to other device activities. This thesis presents a systematic studying of the energy impact of mobile apps features. Time-series electrical current measurements are collected from 4 different modern smartphones. Statistical analysis methodologies are used to calculate the energy impact of each app feature by identifying and extracting mobile app-feature events from the overall current signal. In addition, the app overhead energy costs are also computed. Total energy consumption equations for each component is developed and an overall total energy consumption equation is presented. Minutes Lost (ML) of normal phone operations due to the energy consumption of the mobile app functionality is computed for cases where the mobile app is simulated to run on the various devices for 30 minutes. Tutela Technologies Inc. mobile app, NAT, is used for this study. NAT has two main features: QoS and Throughput. The impact of the QoS feature is indistinguishable, i.e. ML is zero, relative to other phone activities. The ML with only the TP feature enabled is on average 2.1 minutes. Enabling the GPS increases the ML on average to 11.5 minutes. Displaying the app GUI interface in addition to running the app features and enabling the GPS results in an average ML of 12.4 minutes. Amongst the various mobile app features and components studied, the GPS consumes the highest amount of energy. It is estimated that the GPS increases the ML by about 448%.

Download or read book Powering the Dream written by Alexis Madrigal and published by Da Capo Press. This book was released on 2011-03-29 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few today realize that electric cabs dominated Manhattan's streets in the 1890s; that Boise, Idaho, had a geothermal heating system in 1910; or that the first megawatt turbine in the world was built in 1941 by the son of publishing magnate G. P. Putnam -- a feat that would not be duplicated for another forty years. Likewise, while many remember the oil embargo of the 1970s, few are aware that it led to a corresponding explosion in green-technology research that was only derailed when energy prices later dropped. In other words: We've been here before. Although we may have failed, America has had the chance to put our world on a more sustainable path. Americans have, in fact, been inventing green for more than a century. Half compendium of lost opportunities, half hopeful look toward the future, Powering the Dream tells the stories of the brilliant, often irascible inventors who foresaw our current problems, tried to invent cheap and energy renewable solutions, and drew the blueprint for a green future.
Download or read book Mobile Lightweight Wireless Systems written by Periklis Chatzimisios and published by Springer Science & Business Media. This book was released on 2010-10-21 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the success of the First MOBILIGHT 2009 in Athens, Greece, the Second International Conference on Mobile Lightweight Systems (MOBILIGHT) was held in Barcelona, Spain on May 10-12, 2010. It was not an easy decision to carry on organizing a scientific event on wireless communications, where competition is really enormous. This decision was motivated by discussion with many colleagues about the current unprecedented demand for lig- weight, wireless communication devices with high usability and performance able to support added-value services in a highly mobile environment. Such devices follow the users everywhere they go (at work, at home, while travelling, in a classroom, etc. ) and result in exciting research, development and business opportunities. Such scenarios clearly demand significant upgrades to the existing communication paradigm in terms of infrastructure, devices and services to support the “anytime, anywhere, any device” philosophy, providing novel and fast-evolving requirements and expectations on - search and development in the field of information and communication technologies. The core issue is to support wireless users' desire for 24/7 network availability and transparent access to "their own" services. In this context, we continue to envision an international forum where practitioners and researchers coming from the many areas involved in lightweight wireless systems’ design and deployment would be able to interact and exchange experiences.

Book excerpt: Welcome to the proceedings of the 3rd Power-Aware Computer Systems (PACS 2003) Workshop held in conjunction with the 36th Annual International Symposium on Microarchitecture (MICRO-36). The increase in power and - ergy dissipation in computer systems has begun to limit performance and has also resulted in higher cost and lower reliability. The increase also implies - ducedbatterylifeinportablesystems.Becauseofthemagnitudeoftheproblem, alllevelsofcomputersystems,includingcircuits,architectures,andsoftware,are being employed to address power and energy issues. PACS 2003 was the third workshop in its series to explore power- and energy-awareness at all levels of computer systems and brought together experts from academia and industry. These proceedings include 14 research papers, selected from 43 submissions, spanningawidespectrumofareasinpower-awaresystems.Wehavegrouped the papers into the following categories: (1) compilers, (2) embedded systems, (3) microarchitectures, and (4) cache and memory systems. The ?rst paper on compiler techniques proposes pointer reuse analysis that is biased by runtime information (i.e., the targets of pointers are determined based on the likelihood of their occurrence at runtime) to map accesses to ener- e?cient memory access paths (e.g., avoid tag match). Another paper proposes compiling multiple programs together so that disk accesses across the programs can be synchronized to achieve longer sleep times in disks than if the programs are optimized separately.

Download or read book Measurement and Reduction of Power Consumption in Mobile Phones written by Jonathan Adam Lawton and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, consumer adoption of smartphones has been rising rapidly, increasing the demand for high performance mobile devices with long battery life. While the capabilities of mobile systems-on-chip have scaled impressively, battery technology has seen only a modest improvement. In order to address this gap, new power management schemes are needed for the mobile environment. This work proposes adding real-time hardware power measurement to smartphones in order to enable more advanced power management algorithms. The theoretical basis and power cost of making system-level power measurements is explored, an actual power measurement system implemented and characterized, and a number of power management algorithms implemented and evaluated. It is found that a suitable power measurement system could consume as little as 4 [mu]W based on theoretical limits, and that real time power data can be used to control system clock rate to adhere to target power consumption.

Download or read book Data Movement Energy Characterization of Emerging Smartphone Workloads for Mobile Platforms written by Dhinakaran Pandiyan and published by . This book was released on 2014 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: A benchmark suite that is representative of the programs a processor typically executes is necessary to understand a processor's performance or energy consumption characteristics. The first contribution of this work addresses this need for mobile platforms with MobileBench, a selection of representative smartphone applications. In smartphones, like any other portable computing systems, energy is a limited resource. Based on the energy characterization of a commercial widely-used smartphone, application cores are found to consume a significant part of the total energy consumption of the device. With this insight, the subsequent part of this thesis focuses on the portion of energy that is spent to move data from the memory system to the application core's internal registers. The primary motivation for this work comes from the relatively higher power consumption associated with a data movement instruction compared to that of an arithmetic instruction. The data movement energy cost is worsened esp. in a System on Chip (SoC) because the amount of data received and exchanged in a SoC based smartphone increases at an explosive rate. A detailed investigation is performed to quantify the impact of data movement on the overall energy consumption of a smartphone device. To aid this study, microbenchmarks that generate desired data movement patterns between different levels of the memory hierarchy are designed. Energy costs of data movement are then computed by measuring the instantaneous power consumption of the device when the micro benchmarks are executed. This work makes an extensive use of hardware performance counters to validate the memory access behavior of microbenchmarks and to characterize the energy consumed in moving data. Finally, the calculated energy costs of data movement are used to characterize the portion of energy that MobileBench applications spend in moving data. The results of this study show that a significant 35% of the total device energy is spent in data movement alone. Energy is an increasingly important criteria in the context of designing architectures for future smartphones and this thesis offers insights into data movement energy consumption.
