Telecommunications systems have been evolving from the conventional telephone network that mainly deals with voice, to the ISDN (integrated services digital net work) integrating voice, data and image. Moreover, the ATM (asynchronous trans fer mode) and optical switching technologies are being developed for the broadband ISDN which can handle the high speed video communications as well. Computer networks are also progressing from centralized TSS (time-sharing system) to dis tributed LAN (local area network) and VAN (value added network). In the research, development, design and operation of such telecommunications and computer networks, the important problems are determining the optimum con figuration and dimensions of the systems for providing a given performance or GOS (grade of service). The teletraflic theory, the basis for the performance evaluation and the dimensioning, has been studied along with the switching technology, and has developed rapidly by incorporating the recent advances in OR (operations research) and queueing theory. However, it is sometimes difficult for non-experts of teletraffic to understand and apply these theories, because they require a deep mathematical background.
This book constitutes the refereed proceedings of the 7th International Conference on Next Generation Teletraffic and Wired/Wireless Advanced Networking, NEW2AN 2007. The 39 revised full papers presented were carefully reviewed and selected from a total of 113 submissions. The papers are organized in topical sections on teletraffic, traffic characterization and modeling, 3G/UMTS, sensor networks, WLAN, QoS, MANETs, lower layer techniques, PAN technologies, and TCP.
The International Teletraffic Congress (ITC) is a recognized international organization taking part in the work of the International Telecommunications Union. The congress traditionally deals with the development of teletraffic theory and its applications to the design, planning and operation of telecommunication systems, networks and services. The contents of ITC 14 illustrate the important role of teletraffic in the current period of rapid evolution of telecommunication networks. A large number of papers address the teletraffic issues behind developments in broadband communications and ATM technology. The extension of possiblities for user mobility and personal communications together with the generalization of common channnel signalling and the provision of new intelligent network services are further extremely significant developments whose teletraffic implications are explored in a number of contributions. ITC 14 also addresses traditional teletraffic subjects, proposing enhancements to traffic engineering practices for existing circuit and packet switched telecommunications networks and making valuable original contributions to the fundamental mathematical tools on which teletraffic theory is based. The contents of these Proceedings accurately reflect the extremely wide scope of the ITC, extending from basic mathematical theory to day-to-day traffic engineering practices, and constitute the state of the art in 1994 of one of the fundamental telecommunications sciences.
This book constitutes the refereed proceedings of the 6th International Conference on Next Generation Teletraffic and Wired/Wireless Advanced Networking, NEW2AN 2006, held in St. Petersburg, Russia in May/June 2006. The 49 revised full papers presented together with 2 keynote talks were carefully reviewed and selected from a total of 137 submissions. The papers are organized in topical sections on teletraffic, traffic characterization and modeling, 3G/UMTS, sensor networks, WLAN, QoS, MANETs, lower layer techniques, PAN technologies, and TCP.
Contemporary information networks are developing to meet social demands, and as a result new technologies and systems are being introduced. The fundamental problem in this process is the optimization of system dimensions and configuration for a particular level of performance. In the second edition of this innovative text, basic teletraffic theories and their applications are described in detail and practical formulae for advanced models, with references for further reading, are provided. Examples and exercises illustrate the theories' application to real systems. The revised and expanded text includes sections on ATM (asynchronous transfer mode) with the latest performance evaluations for mixed bursty traffic and bursty traffic with finite buffers, and LANs (local area networks) with an improved performance evaluation method for CSMD/CD (Ethernet). Explanations throughout the book have also been refined. The second edition of Teletraffic is a translation and expansion of the original Japanese text by two leading authors. It enables researchers, engineers and telecommunication and computer network managers, even those not experts in teletraffic, to put the latest theories and engineering into practice.
This most recent book from the International Teletraffic Congress Workshops provides valuable insights to the teletraffic engineering particularities and problems often found in developing countries. The editors continue the excellence of previous ITC volumes (Vol. 14, 1991, edited by A. Jensen and V.B. Iversen and Vol. 15, 1991, edited by J.W. Cohen and C.B. Pack) by providing a collection of papers covering a wide variety of planning and implementation issues including: the engineering of systems, methods of habit-examination of users with regard to various types of services, network management, tariff considerations and systems engineering & traffic engineering. A final section providing historical highlights in the field is additionally included.
By deploying time series analysis, Fourier transform, functional analysis, min-plus convolution, and fractional order systems and noise, this book proposes fractal traffic modeling and computations of delay bounds, aiming to improve the quality of service in computer communication networks. As opposed to traditional studies of teletraffic delay bounds, the author proposes a novel fractional noise, the generalized fractional Gaussian noise (gfGn) approach, and introduces a new fractional noise, generalized Cauchy (GC) process for traffic modeling. Researchers and graduates in computer science, applied statistics, and applied mathematics will find this book beneficial. Ming Li, PhD, is a professor at Ocean College, Zhejiang University, and the East China Normal University. He has been an active contributor for many years to the fields of computer communications, applied mathematics and statistics, particularly network traffic modeling, fractal time series, and fractional oscillations. He has authored more than 200 articles and 5 monographs on the subjects. He was identified as the Most Cited Chinese Researcher by Elsevier in 2014–2020. Professor Li was recognized as a top 100,000 scholar in all fields in 2019–2020 and a top 2% scholar in the field of Numerical and Computational Mathematics in 2021 by Prof. John P. A. Ioannidis, Stanford University.
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.
