This book presents effective ways to partition mobile devices such that the enterprise system access and its information are completely separated from the personal information. For those using mobile devices for personal and business purposes, the ability to keep the data secure and separate is critical. The applications for security in smart platforms range from personal email accounts to global enterprise systems. Several approaches for mobile virtualization are described, all creating secure and secluded environments for enterprise information. The authors present a reference architecture that allows for integration with existing enterprise mobile device management systems and provides a lightweight solution for containerizing mobile applications. This solution is then benchmarked with several of the existing mobile virtualization solutions across a range of mobile devices. Virtualization Techniques for Mobile Systems is an excellent resource for researchers and professionals working in mobile systems. Advanced-level students studying computer science and electrical engineering will also find the content helpful.

Mobile Learning and Higher Education provides case studies of mobile learning in higher education settings to showcase how devices can transform learning at the undergraduate and graduate levels. With the rapid diffusion of networked technologies among the adult populations of many countries and the supersession of the once-ubiquitous lecture approach with active learner-centered teaching for deep understanding, mobile devices are increasingly used in higher education classrooms to offer unique and effective new approaches to teaching and learning. A cutting-edge research volume, this collection also provides a springboard for building better practices in higher education institutions.

This book addresses current technology trends and requirements leading towards the next era in mobile communication handsets; and beyond that the book proposes innovative solutions that could be candidate solutions for 5G phones. It adopts a multidisciplinary and interdisciplinary stance towards handset design, a necessary ingredient if 5th Generation handset and services are to really take-off. Therefore the scope of the book targets a broad range of subjects, including energy efficiency, RF design, cooperation, context-aware systems, roaming, and short-range networking, all of which working in synergy to provide seamless mobility and high speed connectivity within a HetNet environment.

This brief surveys existing techniques to address the problem of long delays and high power consumption for web browsing on smartphones, which can be due to the local computational limitation at the smartphone (e.g., running java scripts or flash objects) level. To address this issue, an architecture called Virtual-Machine based Proxy (VMP) is introduced, shifting the computing from smartphones to the VMP which may reside in the cloud. Mobile Web Browsing Using the Cloud illustrates the feasibility of deploying the proposed VMP system in 3G networks through a prototype using Xen virtual machines (in cloud) and Android Phones with ATT UMTS network. Techniques to address scalability issues, resource management techniques to optimize the performance of the VMs on the proxy side, compression techniques to further reduce the bandwidth consumption, and adaptation techniques to address poor network conditions on the smartphone are also included.

The iPhone represents an important moment in both the short history of mobile media and the long history of cultural technologies. Like the Walkman of the 1980s, it marks a juncture in which notions about identity, individualism, lifestyle and sociality require rearticulation. this book explores not only the iPhone's particular characteristics, uses and "affects," but also how the "iPhone moment" functions as a barometer for broader patterns of change. In the iPhone moment, this study considers the convergent trajectories in the evolution of digital and mobile culture, and their implications for future scholarship. Through the lens of the iPhone-as a symbol, culture and a set of material practices around contemporary convergent mobile media-the essays collected here explore the most productive theoretical and methodological approaches for grasping media practice, consumer culture and networked communication in the twenty-first century.

Design and development of a cost-effective mobile broadband wireless access network is a key challenge for many mobile network operators. Overdimensioning or underdimensioning of the access network results in additional costs and a reduction of the customer satisfaction, respectively. Thushara Weerawardane introduces new transport technologies and features for High Speed Packet Access (HSPA) and Long-Term Evolution (LTE) networks. He proposes novel adaptive flow control and enhanced congestion control algorithms and develops corresponding analytical models. These models are based on Markov chains and can be performed for faster analysis evaluation compared to long lasting detailed simulations. Both simulation and analytical models provide optimum network performance and reliable guaranteed quality of standard for the end users during congestion in the transport network. Further, the author investigates and analyzes the LTE transport network performance by introducing novel traffic differentiation models and buffer management techniques during intra-LTE handovers.

Mobile phones are no longer what they used to be. Not only can users connect to the Internet anywhere and anytime, they can also use their devices to map their precise geographic coordinates and access location-specific information like restaurant reviews, historical information, and locations of other people nearby. The proliferation of location-aware mobile technologies calls for a new understanding of how we define public spaces, how we deal with locational privacy, and how networks of power are developed today.

In Mobile Interfaces in Public Spaces, Adriana de Souza E. Silva and Jordan Frith examine these social and spatial changes by framing the development of location-aware technology within the context of other mobile and portable technologies such as the book, the Walkman, the iPod, and the mobile phone. These technologies work as interfaces to public spaces that is, as symbolic systems that not only filter information but also reshape communication relationships and the environment in which social interaction takes place. Yet rather than detaching people from their surroundings, the authors suggest that location-aware technologies may ultimately strengthen our connections to locations.

This international, interdisciplinary collection explores a range of possible theoretical and empirical approaches to cultural technologies and mobile communication by treating the iPhone as a case study. As the mobile phone graduates into a fully web-capable and multi-media device, the contributors to this volume critically examine the nature and implications of this shift, considering the iPhone as a significant moment in media history.

With the emergence of networked, convergent mobile media devices like the iPhone, new media and communication practices are emerging. Increasingly, the mobile phone is becoming a platform for gaming, online social networking and emergent lifestyle applications. The iPhone is symbolic of this phenomenon, but it also has its own distinctive features (in terms of branding and use), and so provides media and communication theorists with a unique opportunity to explore these practices. Indeed, the iPhone--as part of broader shifts toward ubiquitous, convergent mobile devices and "smartphones"--can be usefully deployed as a case study enabling new insights into mobile media culture.

Just as consumer demands for mobile devices have risen rapidly, the use of cell phones by prison inmates has grown as the U.S. prison population continues to expand. This use is considered contraband by prison officials. The number of cell phones confiscated by prison officials has dramatically increased in only a few years. This increase in unauthorised cell phone use by inmates is a mounting concern among correctional administrators across the country. This book investigates and examines wireless technology solutions to prevent contraband cell phone use in prisons, such as jamming, managed access, and detection.
