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.
