Advances in Queueing Theory and Network Applications presents several useful mathematical analyses in queueing theory and mathematical models of key technologies in wired and wireless communication networks such as channel access controls, Internet applications, topology construction, energy saving schemes, and transmission scheduling. In sixteen high quality chapters, this work provides novel ideas, new analytical models, and simulation and experimental results by experts in the field of queueing theory and network applications.The text serves as a state-of-the-art reference for a wide range of researchers and engineers engaged in the fields of queueing theory and network applications, and can also serve as supplemental material for advanced courses in operations research, queueing theory, performance analysis, traffic theory, as well as theoretical design and management of communication networks.

This text covers recent research results in the architecture and performance evaluation of technology associated with LAN and MAN communication systems. It contains the selected proceedings of the Third International Conference on Local and Metropolitan Communications Systems, organized by the International Federation for Information Processing and held in Kyoto, Japan, December 1994. The book assesses new technology in LAN and MAN, and explores the modelling and analysis of communication systems. Specific topics covered by Local and Metropolitan Communication Systems include: network management; multicast; ATM switch; ATM multiplexing; ATM traffic characterization; DQDB; new protocols in LAN and MAN; queuing models related to LAN and MAN. All those concerned with LAN and MAN systems will find this book of use, especially engineers, university professors and lecturers and those working in research and development. This book should be of interest to engineers and researchers in telecommunications and information technology.

With the proliferation of ISDN and mobile communication systems, modern commu­ nication networks are becoming larger-scale, higher-speed, and more complex than ever before. Therefore, besides hardware development, extensive research on system technolo­ gies with respect to the performance evaluation and management is indispensable for the proper design, development and operation of future complex communication networks. The International Conference on the Performance and Management of Complex Com­ munication Systems (PMCCN '97) was held from November 17 to 21, 1997, at Tsukuba Science City, Japan. This was the fifth international conference on the performance as­ pects of communication networks held every three years in Japan (1985 in Tokyo; 1988, 1991, and 1994 in Kyoto). The conference was sponsored by the International Federa­ tion of Information Processing (IFIP) Working Group (WG) 6.3 Performance of Com­ munication Systems, and 7.3 Computer System Modelling, University of Tsukuba, Kyoto University, and The Telecommunication Advancement Foundation (TAF).

Presents the model and methodology, applied by ITU-R WRC’07, to calculate the spectrum requirement  Spectrum Requirement Planning in Wireless Communications: Model and Methodology for IMT-Advanced   is a self-contained “handbook” of the models and methodologies used for the spectrum requirement calculation for IMT-Advanced systems, as well as for the predecessor IMT-2000 systems.  The reader will learn how the spectrum requirement is calculated for real systems that prevail worldwide. The book also provides the basis on which to develop advanced methodologies for yet future systems, as the spectrum regulation will continue in the future.  Spectrum Requirement Planning in Wireless Communications: Model and Methodology for IMT-Advanced Provides the reader with information on how the spectrum requirement is calculated for real systems that prevail worldwideContains useful tables and examples such as flowchart of the methodologyIntroduces definitions of service category and radio environment, the process of distributing traffic to radio environments, and the method to calculate the required spectrumApplies queueing and loss models for the calculation of required system capacityCovers utilization of radio frequencies, market data, spectrum requirement calculation methods for IMT-2000 and for IMT-Advanced systemsInstructs how to use the calculation tool package  Comes with an accompanying website with the downloadable tool applied by ITU-R WRC’07 for making decisions on spectrum regulation for mobile systemsThis book serves as an invaluable guide to engineers in mobile phone companies, system design engineers, operator system engineers and other specialists dealing with mobile system planning and development. It is also of great interest to researchers and graduate students in the fields of applied probability theory, operations research, telecommunications, and mobile networks engineering.

The advancement of key technologies in communication, such as optical and radio transmission, coding schemes, switching mechanisms etc. , has meant that communication networks are quickly growing to a larger-scale and higher speed than was ever anticipated. In terms of usage, Internet and real-time ap­ plications are expected to share a significant portion of the bandwidth in the next-generation of communication networks. Therefore, in order to achieve seamless and Quality of Service (QoS)-guaranteed transmission, regardless of source characteristics, extensive research into networking technologies is es­ sential. For the proper design, development and operation of emerging ideas on networking, further studies on the performance modeling and evaluation of networking are also encouraged. The International Conference on the Performance and QoS of Next Gen­ eration Networking (P&QNet2000) is being held from November 27 to 29, 2000, in Nagoya, Japan (Seto Campus of Nanzan University). This is the sixth international conference on the performance and other aspects of com­ munication networks. The conference is held once every three years in Japan (1985 in Tokyo; 1988, 1991, and 1994 in Kyoto; 1997 in Tsukuba). The confer­ ence is sponsored by the International Federation of Information Processing (IFIP) Working Group (WG) 6. 3 Performance of Communication Systems, 6. 4 High Performance Networking, and 7. 3 Computer System Modelling. Fi­ nancial supports are given by Commemorative Association for the Japan­ World Exposition (1970), Support Center for Advanced Telecommunications Technology Research, and Nanzan University.

We are witnessing an ever-increasing thrust toward the era of multimedia information networks, largely spurred by the U.S. Government's proposal for the National Information Infrastructure in the fall of 1993. While more people are subscribing to the services of narrowband ISDN, the implementation of broadband ISDN by means of Asynchronous Transfer Mode (ATM) has accelerated since the formation of the ATM Forum in 1993. In the meantime, frame relay may prevail for inter-LAN connections. In the "upper layer" of the network, commercial use of Internet is rapidly emerging. To ensure the successful development of technology, it is vital to use a judicious approach in assessing the architecture and performance of the systems that implement the technology. It is this spirit that underlies the present conference, which is intended to provide an international forum for the presentation of recent research results in the area of local and metropolitan communication systems. This conference has two sets of predecessors. It is the third in a series of international conferences on Local and Metropolitan Communication Systems -LAN & MAN; the first was held in Toulouse in 1986 and the second in Palma de Mallorca in 1991. It is also the fourth in a triennial series organized by Kyoto University and others on the performance of communication-related systems; the previous ones were held in Tokyo (1985) and Kyoto (1988, 1991).
