Linux Foundation to Host Meego Workgroup
Linux Foundation To Host MeeGo Workgroup New Open Source Software Platform Backed by Intel and Nokia will Power the Next Generation of Computing Devices SAN FRANCISCO, February 15, 2010 – The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced it will host the MeeGo project, the open source software platform for the next generation of computing devices. MeeGo combines Intel’s Moblin™ and Nokia’s Maemo projects into one Linux-based platform. MeeGo, announced today in a joint release by Intel and Nokia, will be deployed across many computing device types - including pocketable mobile computers, netbooks, tablets, mediaphones, connected TVs and in-vehicle infotainment systems, and brings together the leaders in computing and mobile communications as the project’s backers. MeeGo is designed for cross-device, cross-architecture computing and is built from the ground up for a new class of powerful computing devices. The workgroup will be hosted by the Linux Foundation as a fully open source project, encouraging community contributions in line with the best practices of the open source development model. The Linux Foundation expects MeeGo to be adopted widely by device manufacturers, network operators, software vendors and developers across multiple device types and for many organizations and developers to participate in the workgroup. “With MeeGo, you have the world’s leader in computing – Intel – uniting with the world’s leader in communications – Nokia – in a true open source project hosted at the Linux Foundation,” said Jim Zemlin, executive director at the Linux Foundation. “MeeGo has been built from the ground up for rich, mobile devices and will deliver choice to consumers without lock-in. -

Invariably the technology enables a new means of interacting with screen-based entertainment or a computer game - 3DTV, the Nintendo Wii. The proliferation of so-called ‘smartphones’ with their abilities to run once-complex computer applications, in-built cameras and ‘GPS’ capability has unleashed the potential of ‘Augmented Reality’ – to date a regular feature of science fiction or ‘near future’ movies. -
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.
