Download or read book Quality of Experience for Multimedia written by Abdelhamid Mellouk and published by John Wiley & Sons. This book was released on 2013-11-25 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a convergence of network technologies, the Next Generation Network (NGN) is being deployed to carry high quality video and voice data. In fact, the convergence of network technologies has been driven by the converging needs of end-users. The perceived end-to-end quality is one of the main goals required by users that must be guaranteed by the network operators and the Internet Service Providers, through manufacturer equipment. This is referred to as the notion of Quality of Experience (QoE) and is becoming commonly used to represent user perception. The QoE is not a technical metric, but rather a concept consisting of all elements of a user's perception of the network services. The authors of this book focus on the idea of how to integrate the QoE into a control-command chain in order to construct an adaptive network system. More precisely, in the context of Content-Oriented Networks used to redesign the current Internet architecture to accommodate content-oriented applications and services, they aim to describe an end-to-end QoE model applied to a Content Distribution Network architecture.

This book was released on 2015-05-31 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the volume of global Internet traffic increases, the Internet is beginning to suffer from a broad spectrum of performance-degrading infrastructural limitations that threaten to jeopardize the continued growth of new, innovative services. In answer to this challenge, computer scientists seek to maintain the original design principles of the Internet while allowing for a more dynamic approach to the manner in which networks are designed and operated. The Handbook of Research on Redesigning the Future of Internet Architectures covers some of the hottest topics currently being debated by the Internet community at large, including Internet governance, privacy issues, service delivery automation, advanced networking schemes, and new approaches to Internet traffic-forwarding and path-computation mechanics. Targeting students, network-engineers, and technical strategists, this book seeks to provide a broad and comprehensive look at the next wave of revolutionary ideas poised to reshape the very foundation of the Internet as we know it.

Download or read book Wired Wireless Internet Communications written by Evgeny Osipov and published by Springer. This book was released on 2010-05-12 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the first event in 2002, the International Conference on Wired/ Wireless Internet Communications (WWIC) has continuously been established as a highly selective conference focusing on integration and co-existence of rapidly dev- oping wireless network technologies and their applications related to the Internet. To do so WWIC provides an international forum for presenting and discussing cutti- edge research in this domain, and the 8th edition of WWIC, held at Luleå University in June 2010, continued this tradition. The WWIC 2010 call for papers attracted 45 submissions from more than 25 countries and each contribution was subject to thorough peer review by recognized int- national experts that acted as members of the Technical Program Committee. The selection process resulted in 16 accepted papers, which were thematically grouped into 5 technical sessions. The major themes of WWIC 2010 were cooperation, management of multimedia traffic, advancing IEEE 802.11, cognitive optimization, mesh and multi-hop networks, security, signaling, control, and wireless sensor networks.
Download or read book Development of Field Propagation Model for Urban Area written by Purnima K Sharma and published by diplom.de. This book was released on 2017-03-08 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication is one of the most dynamic and vibrant areas of technology development in the communication field today. It has been found that severe climatic conditions disturb the propagation of electromagnetic signals at higher frequencies (greater than 30 MHz). The disturbance is mainly due to molecular absorption by oxygen for frequencies ranging between 60 and 118 GHz and due to water vapour in 22, 183 and 325 GHz bands. Rain and fog has the most significant impact, since the size of the rain drops is of the order of the wavelength of the transmitted signal. This results in energy absorption by the rain drops themselves, and as a secondary effect energy is scattered by the drops. The frequency selective absorption characteristics of the atmosphere can be approximated by a transfer function. In most of the practical channels when the signal propagates through the atmosphere the effect of many factors on the signal has to be considered along with the free space propagation channel assumption. The main objective of this study is, therefore, to find out whether, and how, the different climatic conditions are influencing radio wave propagation in GSM frequency bands in general and in Narnaul, Haryana (India) in particular. To carry out this investigation, the records of radio wave propagation along with path loss during different climatic conditions have been analyzed. On the strength of these analyses, a propagation path loss model has been developed by proposing suitable correction factors due to different climatic conditions. The validation of this developed path loss model has been verified by taking reference models and by applying practically in different urban areas. The effect of these climatic conditions on the link budget has also been analyzed.
