Local Networks and the Internet

Introducing the basic concepts in total program control of the intelligent agents and machines, Intelligent Internet Knowledge Networks explores the design and architecture of information systems that include and emphasize the interactive role of modern computer/communication systems and human beings. Here, you’ll discover specific network configurations that sense environments, presented through case studies of IT platforms, electrical governments, medical networks, and educational networks.

Online, the opportunity to commit a crime is never more than a few clicks away. Sex Offenders and the Internet explores the nature of online sex offenders in order to help practitioners understand and treat this new category of client. Kerry Sheldon and Dennis Howitt examine the research base by reviewing case studies and psychological profiles, with a particular focus on paedophilic Internet sex offenders. Issues covered include child pornography, the often overlooked ‘excuses’ for paedophilia, and how we can move forward. The result is a book that comprehensively details the nature of Internet sex offenders, bringing together the relevant research into one essential volume.

The first chapter of this title concerns virtualization techniques that allow sharing computational resources basically, slicing a real computational environment into virtual computational environments that are isolated from one another. The Xen and OpenFlow virtualization platforms are then presented in Chapter 2 and a performance analysis of both is provided. This chapter also defines the primitives that the network virtualization infrastructure must provide for allowing the piloting plane to manage virtual network elements. Following this, interfaces for system management of the two platforms are proposed in Chapter 3. To control and manage virtual network elements, five primitives that the network virtualization infrastructure must provide are defined: instantiate, delete, migrate, monitor and set. The book then moves on to survey existing control algorithms for virtual networking. It also describes the main challenges for packet forwarding using Xen as a virtualization tool and describes, in more detail, a proposal for local control of virtual networks. Within each physical node, this proposal guarantees the service level acquired by each virtual network, even in the presence of misbehaving virtual networks. Contents 1.

No topic is more central to innovation and current practice in testing and assessment today than computers and the Internet. This timely publication highlights four main themes that define current issues, technical advances and applications of computer-based testing: Advances in computer-based testing – new test designs, item selection algorithms, exposure control issues and methods, and new tests that capitalize on the power of computer technology. Operational issues – systems design, test security, and legal and ethical matters. New and improved uses – for tests in employment and credentialing. The future of computer-based testing – identifying potential issues, developments, major advances and problems to overcome. Written by internationally recognized contributors, each chapter focuses on issues of control, quality, security and technology. These issues provide the basic structure for the International Test Commission's new Guidelines on Computer-Based Testing and Testing on the Internet. The contributions to this book have played a key role in the development of these guidelines. Computer-Based Testing and the Internet is a comprehensive guide for all professionals, academics and practitioners working in the fields of education, credentialing, personnel testing and organizational assessment. It will also be of value to students developing expertise in these areas.

RFID (Radio Frequency Identification) technology allows for automatic identification of information contained in a tag by scanning and interrogation using radio frequency (RF) waves. An RFID tag contains an antenna and a microchip that allows it to transmit and receive. This technology is a possible alternative to the use of barcodes, which are frequently inadequate in the face of rapid growth in the scale and complexity of just-in-time inventory requirements, regional and international trade, and emerging new methods of trade based on it. Use of RFID tags will likely eventually become as widespread as barcodes today. This book describes the technologies used for implementation of RFID: from hardware, communication protocols, cryptography, to applications (including electronic product codes, or EPC) and middleware. The five parts of this book will provide the reader with a detailed description of all the elements that make up a RFID system today, including hot topics such as the privacy concerns, and the Internet of Things.

This book presents the state of the art in the field of mobile and wireless networks, and anticipates the arrival of new standards and architectures. It focuses on wireless networks, starting with small personal area networks and progressing onto the very large cells of wireless regional area networks, via local area networks dominated by WiFi technology, and finally metropolitan networks. After a description of the existing 2G and 3G standards, with LTE being the latest release, LTE-A is addressed, which is the first 4G release, and a first indication of 5G is provided as seen through the standardizing bodies. 4G technology is described in detail along with the different LTE extensions related to the massive arrival of femtocells, the increase to a 1 Gbps capacity, and relay techniques. 5G is also discussed in order to show what can be expected in the near future. The Internet of Things is explained in a specific chapter due to its omnipresence in the literature, ad hoc and mesh networks form another important chapter as they have made a comeback after a long period of near hibernation, and the final chapter discusses a particularly recent topic: Mobile-Edge Computing (MEC) servers.

This book discusses the media, beliefs, the news, the Internet, etc. but it should not be seen as yet another critique of the media system, exploring with indignant fascination the idea of a machination against truth set up to serve a society of domination. These kinds of theories, whether they pertain to conspiracy theories or, more subtly, to a self-styled «critical» way of thinking, have always seemed to be the expression of a form of intellectual puerility. This is not to say that attempts at manipulating opinions do not occur, or that our world is free from compromised principles, or indeed corruption; far from it, but none of this is the key issue. In fact, reality can somehow be even more unsettling than those myths, however sophisticated they may be, that envisage the media system hand-in-hand with industry, science, and so forth, all in agreement so as to lead the «people» away from the truth. It is more unsettling because the processes described in this book and that allow falsehood and dubiousness to take hold of the public sphere are boosted by the development of IT, the workings of our minds, and the very nature of democracy. And finally, it is more unsettling because we are all responsible for what is going to happen to us.

The book gives an overview of what these technologies are likely to offer, of their architectures, protocols and functionality. It also discusses their differences and similarities, and whether they will qualify as 4G. Key Features: Provides readers, particularly those with a background in IP-based networks, with a technical understanding of what UMTS does, how it works and how it is likely to evolve Explains the differences in design between UMTS Networks and Computer Networks and discusses how these design divergences can be reconciled in the future Shows how economic considerations shape the design of UMTS Motivates why particular design choices are made in UMTS Gives an in-depth introduction to LTE / SAE Provides a detailed picture of the state of the art in 4G Illustrates the theory with numerous tables and figures This comprehensive textbook is essential reading for advanced students and lecturers in communications systems and networking.
