  • An Analysis of Power Consumption in a Smartphone
    An Analysis of Power Consumption in a Smartphone Josh Hildebrand Introduction l Mobile devices derive the energy required to operate from batteries that are limited by the size of the device. l The ability to manage energy usage requires a good understanding of where and how the energy is being used. l The advancing functionality of modern smartphones is increasing the pressure on battery lifetime, and increases the need for effective energy management. l Goal is to break down a modern smartphone and measure the power consumption of the devices major subsystems, under a range of usage scenarios. l Results from the breakdown of energy consumption will be validated against two additional mobile devices. l Finally, an analysis of the energy consumption will be performed, and an energy model will be created to allow us to model usage patterns. Methodology / Device Under Test l The approach is to take physical power measurements at the component level on a piece of real hardware. l Three elements to the experimental setup, the device under test, a hardware data acquisition (DAQ) system, and a host computer. l Device under test is the Openmoko Neo Freerunner 2.5G smartphone. Experimental Setup l To measure power to each component, supply voltage and current must be measured. l Current is measured by placing sense resistors on the power supply rails of each component. Resistors were selected such that the voltage drop did not exceed 10mV, less than 1% of the supply voltage. l Voltages were measured using a National Instruments PCI-6229 DAQ. Software l The device was running the Freerunner port of Android 1.5, using the Linux v2.6.29 kernel.

  • A Survey Onmobile Operating System and Mobile Networks
    A SURVEY ONMOBILE OPERATING SYSTEM AND MOBILE NETWORKS Vignesh Kumar K1, Nagarajan R2 (1Departmen of Computer Science, PhD Research Scholar, Sri Ramakrishna College of Arts And Science, India) (2Department of Computer Science, Assistant Professor, Sri Ramakrishna College Of Arts And Science, India) ABSTRACT The use of smartphones is growing at an unprecedented rate and is projected to soon passlaptops as consumers’ mobile platform of choice. The proliferation of these devices hascreated new opportunities for mobile researchers; however, when faced with hundreds ofdevices across nearly a dozen development platforms, selecting the ideal platform is often met with unanswered questions. This paper considers desirable characteristics of mobileplatforms necessary for mobile networks research. Key words:smart phones,platforms, mobile networks,mobileplatforms. I.INTRODUCTION In a mobile network, position of MNs has been changing due todynamic nature. The dynamic movements of MNs are tracked regularlyby MM. To meet the QoS in mobile networks, the various issuesconsidered such as MM, handoff methods, call dropping, call blockingmethods, network throughput, routing overhead and PDR are discussed. In this paper I analyse the five most popular smartphone platforms: Android (Linux), BlackBerry, IPhone, Symbian, and Windows Mobile. Each has its own set of strengths and weaknesses; some platforms trade off security for openness, code portability for stability, and limit APIs for robustness. This analysis focuses on the APIs that platforms expose to applications; however in practice, smartphones are manufactured with different physical functionality. Therefore certain platform APIs may not be available on all smartphones. II.MOBILITY MANAGEMENT IP mobility management protocols proposed by Alnasouri et al (2007), Dell'Uomo and Scarrone (2002) and He and Cheng (2011) are compared in terms of handoff latency and packet loss during HM.

  • Download Android Os for Phone Open Source Mobile OS Alternatives to Android
    download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily.
