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. -

1 Smartphones and Symbian OS
1 Smartphones and Symbian OS Symbian OS is a full-featured, open, mobile operating system that powers many of today’s smartphones. As these smartphones become more pow- erful and popular, the demand for smartphone software has grown. Symbian smartphones are shipped with a variety of useful pre-loaded and targeted applications, which are selected by each phone’s manu- facturer. Today, the average Symbian smartphone ships with over 30 pieces of third-party software pre-installed. However, the exciting aspect of Symbian smartphones is that they are ‘open’, meaning that users can further customize their phone experience by downloading, installing, and uninstalling applications written by third-party developers (or by the users themselves). Users can download applications from a PC to the smartphone through a link such as USB, or Bluetooth technology, or over-the-air via the Internet. With the largest installed base of smartphones worldwide, Symbian OS offers a great opportunity for software developers to establish them- selves in the mobile market by creating novel and exciting software for the growing mass of smartphone users around the world. There is a growing list of Symbian applications available as freeware or as paid downloads on numerous Internet sites (http://www.handango.com and http://www.epocware.com are good examples). They range from pro- ductivity, entertainment, navigation, multimedia, and communications software to programs that can count fast food calories, improve your golfCOPYRIGHTED swing, keep diaries, and calculate MATERIAL foreign currency exchange. And business opportunities aside, sometimes it’s just plain fun writing your own code to run on your own smartphone. -

History of Linux from Wikipedia, the Free Encyclopedia
History of Linux From Wikipedia, the free encyclopedia The history of Linux began in 1991 with the commencement of a personal project by Finnish student Linus Torvalds to create a new free operating system kernel. Since then, the resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 4.2.3 version in 2015 with more than 18 million lines of source code under the GNU General Public License v2.[1](p7)[2][3] Contents 1 Events leading to creation 2 The creation of Linux 3 Naming 4 Linux under the GNU GPL 5 GNU/Linux naming controversy 6 Official mascot 7 New development 7.1 Community 7.2 Open Source Development Lab and Linux Foundation 7.3 Companies 7.4 Desktop environments 8 "Linux is obsolete" 9 Competition from Microsoft 10 SCO 11 Trademark rights 12 Chronology 13 See also 14 References 15 External links Events leading to creation After AT&T had dropped out of the Multics project, the Unix operating system was conceived and implemented by Ken Thompson and Dennis Ritchie (both of AT&T Bell Laboratories) in 1969 and first released in 1970. Later they rewrote it in a new programming language, C, to make it portable. The availability and portability of Unix caused it to be widely adopted, copied and modified by academic institutions and businesses. In 1977, the Berkeley Software Distribution (BSD) was developed by the Computer Systems Research Group (CSRG) from UC Berkeley, based on the 6th edition of Unix from AT&T. -

SAINT LOUIS UNIVERSITY SCHOOL OF LAW A PRIMER ON OPEN SOURCE LICENSING LEGAL ISSUES: COPYRIGHT, COPYLEFT AND COPYFUTURE DENNIS M. KENNEDY* Open Source1 software has recently captured the public attention both because of the attractiveness and growing market share of programs developed under the Open Source model and because of its unique approach to software licensing and community-based programming. The description of Open Source software as “free” and the free price of some of the software undoubtedly attracted other attention. The Open Source movement reflects the intent of its founders to turn traditional notions of copyright, software licensing, distribution, development and even ownership on their heads, even to the point of creating the term “copyleft” to describe the alternative approach to these issues.2 Open Source software plays a significant role in the infrastructure of the Internet and Open Source programs such as Linux, Apache, and BIND are commonly used tools in the Internet and business * Dennis M.
