This book was released on 2007-05-08 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapidly increasing penetration of laptop computers and mobile phones, which are primarily used by mobile users to access Internet s- vices like e-mail and World Wide Web (WWW) access, support of Internet services in a mobile environment is an emerging requirement. Wireless n- works have been used for communication among fully distributed users in a multimedia environment that has the needs to provide real-time bursty traffic (such as voice or video) and data traffic with excellent reliability and service quality. To satisfy the huge wireless multimedia service demand and improve the system performance, efficient channel access methods and analytical methods must be provided. In this way very accurate models, that faithfully reproduce the stochastic behavior of multimedia wireless communication and computer networks, can be constructed. Most of these system models are discrete-time queueing systems. Queueing networks and Markov chains are commonly used for the p- formance and reliability evaluation of computer, communication, and m- ufacturing systems. Although there are quite a few books on the individual topics of queueing networks and Markov chains, we have found none that covers the topics of discrete-time and continuous-time multichannel mul- traffic queueing networks. On the other hand, the design and development of multichannel mul- hop network systems and interconnected network systems or integrated n- works of multimedia traffic require not only such average performance m- sures as the throughput or packet delay but also higher moments of traffic departures and transmission delay.

Available in PDF, EPUB and Kindle. Book excerpt: MPLS is many things to many people. If you’re moving IP voice traffic, it may mean performance gains for you. Daniel Minoli’s Voice Over MPLS gives you the technical and business lowdown on innovative new solutions for packet-based voice. What does it take to build flexible, high-performance networks with enhanced quality of service? Maybe not as much as you think. RELIABLE VOICE SERVICES THAT CUSTOMERS CAN AFFORD With VoMPLS, you can deliver the quality associated with VoIP over ATM links without the cost in either bandwidth or equipment. Based on label-switching standards from the IETF and the work of a number of leading companies, Voice over MPLS lets you packetize voice without the added overhead of IP encapsulation. It also suppresses periods of silence, freeing up bandwidth for other uses. From one of the most experienced names in telecom technology, Voice Over MPLS shows you how to— * Provide multiple, high-quality services without costly leased lines * Deliver low-bandwidth voice over ATM, Frame Relay, or IP * Add phone “lines” without adding equipment * Solve scaling issues for small- and medium-sized users * Obtain consistent call quality without crunching bandwidth * Discover ways to protect revenues during deployment * Evaluate the potential role of VoMPLS in big-picture convergence * Evaluate VoMPLS’s impact on public networks Find the engineering details you need for Label Switched Paths (LSPs), layers, signaling, CoS (Classes of Service), QoS (Quality of Service), VoMPLS in VPNs (Virtual Private Networks), implementation options, deployment, and more.
Download or read book Tactical Communications for the Digitized Battlefield written by Michael J. Ryan and published by Artech House. This book was released on 2002 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional tactical communications systems consist of a number of separate subsystems with little interworking between them and with external sensors and weapons systems. Combat net radio (CNR) has provided the high-mobility communications required by combat troops, while trunk communications systems have provided high-capacity communications between headquarters at the expense of mobility. The focus of this book is on new, information-age technologies that promise to offer seamless integration of real-time data sharing, creating a single logical network architecture to facilitate the movement of data throughout the battlespace. Because the structure of this network is constrained by the fundamental trade-off between range, mobility and capacity that applies to all communications systems, this network is unlikely to be based on a single network technology. This book presents an architecture for this network, and shows how its subsystems can be integrated to form a single logical network.

This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless personal communications, or wireless as it is now being called, has arrived. The hype is starting to fade, and the hard work of deploying new systems and services for personal communications is underway. In the United States, the FCC propelled the wireless era from infancy to mainstream with a $7.7 billion auction of 60 MHz of radio spectrum in the 180011900 MHz band. With the largest single sale of public property in the history of mankind mostly complete, the resources of the entire world are being called upon to develop inexpensive, rapidly deployable wireless systems and sub scriber units for an industry that is adding subscribers at greater than 50% annual rate. This growth is commonplace for wireless service companies throughout the world, and in the U.S., where as many as 7 licensed wireless service providers may be competing for cellularfPCS customers within the next couple of years, differentiators in cost, qual ity, service, and coverage will become critical to customer acceptance and use. Many of these issues are discussed in the papers included in this book.

Download or read book Multiaccess Mobility and Teletraffic for Wireless Communications volume 6 written by Xavier Lagrange and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Third generation networks have been specified and are now being deployed in a few countries. They are expected to reach maturity in the next several years and to provide various services including audio, video, and world wide web browsing. Furthermore, radio terminals are expected to be integrated in a number of devices such as personal computers, personal digital assistants, and even television sets. Such a wide-usage of radio mandates ongoing research to address design of networks with high capacity while providing acceptable quality of service. This volume is the sixth in the edited series Multiaccess, Mobility and Teletraffic for Wireless Communications. It presents the selected papers for the proceedings of the Seventh Workshop (MMT'2002) held on this topic in June 2002 in Rennes, France. The aim of this workshop has been to address a set of important issues of interest to the wireless communications community. In particular, the focus of this workshop is to identify, present and discuss the theoretical and implementation issues critical to the design of land based mobile cellular and microcellular as well as wireless local area networks. Included in this book are recent research results on performance analysis of wireless packet networks, channel coding and receiver design, radio resource management in third generation systems, mobility management in cellular and mobile IP networks, performance of transport protocols (TCP) over radio link control protocols, and ad-hoc networks.
Download or read book 3DTV Content Capture Encoding and Transmission written by Daniel Minoli and published by John Wiley & Sons. This book was released on 2010-12-28 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The First to Present 3D Technology as Applied to Commercial Programming for the Consumer This is the first book to provide an overview of the technologies, standards, and infrastructure required to support the rollout of commercial real-time 3 Dimension Television/3 Dimension Video (3DTV/3DV) services. It reviews the required standards and technologies that have emerged—or are just emerging—in support of such new services, with a focus on encoding mechanisms formats and the buildout of the transport infrastructure. While there is a lot of academic interest in various intrinsic aspects of 3DTV, service providers and consumers ultimately tend to take a system-level view. 3DTV stakeholders need to consider the overall architectural system-level view of what it will take to deploy an infrastructure that is able to reliably and cost-effectively deliver a commercial-grade quality bundle of multiple 3DTV content channels to paying customers with high expectations. This text, therefore, takes such a system-level view, revealing how to actually deploy the technology. Presented in a self-contained, tutorial fashion, the book begins with a review of 3DTV in the marketplace and the opportunities and challenges therein. Recent industry events related to 3D are also discussed. From there, the fundamental visual concepts supporting stereographic perception of 3DTV/3DV are explained, as are encoding approaches. Readers will understand frame mastering and compression for conventional stereo video (CSV) and more advanced methods such as video plus depth (V+D), multi-view video plus depth (MV+D), and layered depth video (LDV). Next, the elements of an end-to-end 3DTV system are covered from a satellite delivery perspective, with explanations of digital video broadcasting (DVB) and DVB-handheld. Transmission technologies are assessed for terrestrial and IPTV-based architecture; IPv6 is reviewed in detail. Finally, the book presents 3DTV/3DV standardization and related activities, which are critical to any type of broad deployment. System planners, the broadcast TV industry, satellite operators, Internet service providers, terrestrial telecommunication carriers, content developers, design engineers, venture capitalists, and students and professors are among those stakeholders in these services, and who will rely on this volume to discover the latest 3D advances, market opportunities, and competing technologies.
