This book describes recent innovations in 3D media and technologies, with coverage of 3D media capturing, processing, encoding, and adaptation, networking aspects for 3D Media, and quality of user experience (QoE). The contributions are based on the results of the FP7 European Project ROMEO, which focuses on new methods for the compression and delivery of 3D multi-view video and spatial audio, as well as the optimization of networking and compression jointly across the future Internet. The delivery of 3D media to individual users remains a highly challenging problem due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user's context such as their preferences and location. As the number of visual views increases, current systems will struggle to meet the demanding requirements in terms of delivery of consistent video quality to fixed and mobile users. ROMEO will present hybrid networking solutions that combine the DVB-T2 and DVB-NGH broadcast access network technologies together with a QoE aware Peer-to-Peer (P2P) distribution system that operates over wired and wireless links. Live streaming 3D media needs to be received by collaborating users at the same time or with imperceptible delay to enable them to watch together while exchanging comments as if they were all in the same location. This book is the last of a series of three annual volumes devoted to the latest results of the FP7 European Project ROMEO. The present volume provides state-of-the-art information on 3D multi-view video, spatial audio networking protocols for 3D media, P2P 3D media streaming, and 3D Media delivery across heterogeneous wireless networks among other topics. Graduate students and professionals in electrical engineering and computer science with an interest in 3D Future Internet Media will find this volume to be essential reading.

The idea of this book comes from the observation that sensor networks represent a topic of interest from both theoretical and practical perspectives. The title und- lines that sensor networks offer the unique opportunity of clearly linking theory with practice. In fact, owing to their typical low-cost, academic researchers have the opportunity of implementing sensor network testbeds to check the validity of their theories, algorithms, protocols, etc., in reality. Likewise, a practitioner has the opportunity of understanding what are the principles behind the sensor networks under use and, thus, how to properly tune some accessible network parameters to improve the performance. On the basis of the observations above, the book has been structured in three parts: PartIisdenotedas"Theory,"sincethetopicsofits vechaptersareapparently "detached" from real scenarios; Part II is denoted as "Theory and Practice," since the topics of its three chapters, altough theoretical, have a clear connection with speci c practical scenarios; Part III is denoted as "Practice," since the topics of its ve chapters are clearly related to practical applications.

Knowledge sharing within an organization is essential to its continued success and growth, though remaining aware of new communication technologies is a difficult task. Web Engineered Applications for Evolving Organizations: Emerging Knowledge explores integrated approaches to IT and Web engineering, offering solutions and best practices for knowledge exchange within organizations. This publication focuses on research in a number of related disciplines, including data knowledge storage and retrieval, intelligent information systems, IT education and training, and IT readiness.

Ashley Friedlein's first book, Web Project Management: Delivering Successful Commercial Web Sites, became a bestseller and an essential reference for Web professionals developing new sites. Maintaining and Evolving Successful Commercial Web Sites addresses the realities of successful sites today, namely the notion that maintaining and evolving a site is actually a bigger commitment than launching it. Management wants to maximize returns and obtain reliable performance data, customers demand better service and insist on sites that are more advanced yet easier to use, and the Web site must increasingly be integrated with the entire business even as the amount of information it handles continues to grow.
Maintaining and Evolving Successful Commercial Web Sites focuses more on process, reality, and pragmatism and less on strategic theory. It provides the reader with the knowledge, tools, approaches, and processes to manage key site maintenance and evolution projects, providing answers to the following questions:
*How can I better manage changes and updates to the Web site?
*How can I scale up to allow more contributions to the site and more content and still maintain quality and control?
*What is content management and how do I go about it?
*How do I go about personalization or community building?
*What is Customer Relationship Management (CRM) and how do I actually do it online?
*How do I measure and report on how well the site is doing?
*How do I avoid information overload?
*How do I maximize the value the site creates?
The book includes case studies to demonstrate candidly how the issues discussed in the book translate into reality.
*Case studies show candidly how the issues discussed translate into reality.
*Describes content management & Customer Relationship Management (CRM) how to go about implementing them.
*Teaches how to measure & report on how well the site is doing, how to avoid information overload, & how to maximize the value the site creates.

The rapid development and expansion of Web-based technologies has vast potential implications for the processes of teaching and learning world-wide. Technological advancements of Web-based applications strike at the base of the education spectrum; however, the scope of experimentation and discussion on this topic has continuously been narrow.

Over the last decade, a great amount of effort and resources have been invested in the development of Semantic Web Service (SWS) frameworks. Numerous description languages, frameworks, tools, and matchmaking and composition algorithms have been proposed. Nevertheless, when faced with a real-world problem, it is still very hard to decide which of these different approaches to use.

In this book, the editors present an overall overview and comparison of the main current evaluation initiatives for SWS. The presentation is divided into four parts, each referring to one of the evaluation initiatives. Part I covers the long-established first two tracks of the Semantic Service Selection (S3) Contest - the OWL-S matchmaker evaluation and the SAWSDL matchmaker evaluation. Part II introduces the new S3 Jena Geography Dataset (JGD) cross evaluation contest. Part III presents the Semantic Web Service Challenge. Lastly, Part IV reports on the semantic aspects of the Web Service Challenge. The introduction to each part provides an overview of the evaluation initiative and overall results for its latest evaluation workshops. The following chapters in each part, written by the participants, detail their approaches, solutions and lessons learned.This book is aimed at two different types of readers. Researchers on SWS technology receive an overview of existing approaches in SWS with a particular focus on evaluation approaches; potential users of SWS technologies receive a comprehensive summary of the respective strengths and weaknesses of current systems and thus guidance on factors that play a role in evaluation.

Today’s publishing infrastructure is rapidly changing. As electronic journals, digital libraries, collaboratories, logic servers, and other knowledge infrastructures emerge on the internet, the key aspects of this transformation need to be identified. Here, the author details the implications that this transformation is having on the creation, dissemination and organization of academic knowledge. The author shows that many established publishing principles need to be given up in order to facilitate this transformation. The text provides valuable insights for knowledge managers, designers of internet-based knowledge infrastructures, and professionals in the publishing industry. Researchers will find the scenarios and implications for research processes stimulating and thought-provoking.

Just like the industrial society of the last century depended on natural resources, today s society depends on information and its exchange.

Semantic Web technologies address the problem of information complexity by providing advanced support for representing and processing distributed information, while peer-to-peer technologies address issues of system complexity by allowing flexible and decentralized information storage and processing. Systems that are based on Semantic Web and peer-to-peer technologies promise to combine the advantages of the two mechanisms. A peer-to-peer style architecture for the Semantic Web will avoid both physical and semantic bottlenecks that limit information and knowledge exchange.

Staab and Stuckenschmidt structured the selected contributions into four parts: Part I, "Data Storage and Access," prepares the semantic foundation, i.e. data modelling and querying in a flexible and yet scalable manner. These foundations allow for dealing with the organization of information at the individual peers. Part II, "Querying the Network," considers the routing of queries, as well as continuous queries and personalized queries under the conditions of the permanently changing topological structure of a peer-to-peer network. Part III, "Semantic Integration," deals with the mapping of heterogeneous data representations. Finally Part IV, "Methodology and Systems," reports experiences from case studies and sample applications.

The overall result is a state-of-the-art description of the potential of Semantic Web and peer-to-peer technologies for information sharing and knowledge management when applied jointly. It serves researchers in academia and industry as an excellent and lasting reference and source of inspiration.

Wireless Sensor Network (WSN) consists of numerous physically distributed autonomous devices used for sensing and monitoring the physical and/or environmental conditions. A WSN uses a gateway that provides wireless connectivity to the wired world as well as distributed networks. There are many open problems related to Ad-Hoc networks and its applications. Looking at the expansion of the cellular infrastructure, Ad-Hoc network may be acting as the basis of the 4th generation wireless technology with the new paradigm of 'anytime, anywhere communications'. To realize this, the real challenge would be the security, authorization and management issues of the large scale WSNs. This book is an edited volume in the broad area of WSNs. The book covers various chapters like Multi-Channel Wireless Sensor Networks, its Coverage, Connectivity as well as Deployment. It covers comparison of various communication protocols and algorithms such as MANNET, ODMRP and ADMR Protocols for Ad hoc Multicasting, Location Based Coordinated Routing Protocol and other Token based group local mutual exclusion Algorithms. The book also covers a chapter on Extended Ad hoc On-Demand Distance Vector (EAODV) routing protocol based on Distributed Minimum Transmission Multicast Routing (DMTMR). One chapter is dedicated to OCDMA and its future application and another chapter covers development of Home Automation System using SWN.

The book provides a comprehensive investigation of the performance and problems of the TCP/IP protocol stack, when data is transmitted over GSM, GPRS and UMTS. It gives an introduction to the protocols used for Internet access today, and also the Wireless Application Protocol (WAP). The basics of GSM, GPRS and UMTS are given, which are necessary for understanding the main topic, TCP performance over GSM, GPRS and UMTS. We describe at length the problems that TCP has when operating over a mobile radio link, and what has been proposed to remedy these problems. We derive the optimum TCP packet length for maximum data throughput on wireless networks, analytically and by simulation. Results on the throughput and various other parameters of TCP over mobile networks are given. This book gives valuable advice to network operators and application programmers to maximize data throughput, and which protocols, transmission modes, and coding schemes to use and which to avoid.
