This authoritative reference provides readers with a thorough understanding of IP Mobility using Mobile IPv6 and companion advanced mobility protocols including network mobility and fast handovers. It illustrates basic concepts and principles behind the IP Mobility architecture and covers the practices using detailed protocol description. Of particular importance is how mobile networking will support billions of devices without restricting applications or overburdening network infrastructures, and how it will support the movement of users from network to network without compromising security.

Authors Koodli and Perkins investigate how IP mobility is used in practice and the adoption of Mobile IPv6 in CDMA cellular systems. They also cover some experimental work, including performance of VoIP handovers over WLAN, multi-access network handovers, and emerging topics such as location privacy.

In five parts, Mobile Inter-networking with IPv6 covers:

• Features of IPv6 and IP security
• Mobility concepts and principles, Mobile IPv6 protocol, packet handling, and network mobility
• Advanced mobility protocols, including fast handovers, fast handover protocol, context transfers, and hierarchical mobility management
• Applying IP mobility, including Mobile IPv6 in CDMA packet data networks, enterprise mobile networking, and WLAN fast handovers
• Emerging topics such as multi-access and mobility, seamless IP handovers, location privacy and IP mobility, and route optimization for Mobile IPv4 using Mobile IPv6 return routability

With chapter exercises and handy references, readers will have plenty of opportunities to pursue topics in further detail. This is a comprehensive reference suitable for practitioners and students with a basic understanding of TCP/IP protocols.

The setting for this book is the networked community. The treatment of the subject matter is broad and interdisciplinary, with contributions from computer science, sociology, design, human factors and communication technology.

The chapter contributors, drawn from across Europe and North America, offer a varied prospectus of commentary, critique, sociological enquiry, technological development and research findings, which provides a rounded account of the progressive intermingling of social and electronic networks.

The contributors discuss the ways in which the Internet affects both familial and social relationships, communal and civic involvement, social capital and work patterns and lifestyle. Civic intelligence is presented as a nascent concept from which future social networks of increased public advocacy, scrutiny and action may be sourced. Other reported developments include agent-based community systems to model and support communal memory and social knowledge.

The opening section provides a purview of the broad scene covered by the book, followed by discussions about the current state of connected communities. Following this there are case studies illustrating the different aspects of research, both sociological and technological, in this area. The final part reports the variety and the scope of technology-mediated human-to-human communication in a connected community setting today.

Pro Active Record helps you take advantage of the full power of your database engine from within your Ruby programs and Rails applications. ActiveRecord, part of the magic that makes the Rails framework so powerful and easy to use, is the model element of Rail's model/view/controller framework. It's an object-relational mapping library enabling you to interact with databases from both Ruby and Rails applications.

Because ActiveRecord is configured with default assumptions that mesh perfectly with the Rails framework, Rails developers often find they hardly need think about it at all. However, if you are developing in Ruby without Rails, or are deploying against legacy databases designed without Rails in mind, or you just want to take advantage of database-specific features such as large objects and stored procedures, you need the in-depth knowledge of ActiveRecord found in this book.

In Pro Active Record, authors Kevin Marshall, Chad Pytel, and Jon Yurek walk you through every step from the basics of getting and installing the ActiveRecord library to working with legacy schema to using features specific to each of today's most popular database engines, including Oracle, MS SQL, MySQL, and more! You’ll come to a deep understanding of ActiveRecord that will enable you to truly exploit all that Ruby, Rails, and your chosen database platform have to offer.
