This new book is an introduction to modern communications networks that now rely far less on telephone services and more on cellular and IP networks. The resource is designed to provide answers to the fundamental questions concerning telecommunications networks and services. This includes the structure and main components of a modern telecommunications network; the importance of standardization; and how cellular mobile networks operate; among many others. In addition, you are provided with problems and review questions to work though and help you master the material.
A modern mathematical approach to the design of communication networks for graduate students, blending control, optimization, and stochastic network theories alongside a broad range of performance analysis tools. Practical applications are illustrated by making connections to network algorithms and protocols. End-of-chapter problems covering a range of difficulties support student learning.
Evaluating the performance of communications and computer systems constitutes a challenge. This volume contains contributions and presentations made by international researchers at a workshop which was held in April 2004 to honour Professor Erol Gelenbe on the occasion of his inaugural lecture as the Dennis Gabor Chair at Imperial College London.
Most animal communication has evolved and now takes place in the context of a communication network, i.e. several signallers and receivers within communication range of each other. This idea follows naturally from the observation that many signals travel further than the average spacing between animals. This is self evidently true for long-range signals, but at a high density the same is true for short-range signals (e.g. begging calls of nestling birds). This book provides a current summary of research on communication networks and appraises future prospects. It combines information from studies of several taxonomic groups (insects to people via fiddler crabs, fish, frogs, birds and mammals) and several signalling modalities (visual, acoustic and chemical signals). It also specifically addresses the many areas of interface between communication networks and other disciplines (from the evolution of human charitable behaviour to the psychophysics of signal perception, via social behaviour, physiology and mathematical models).
Few would doubt the potential of information technology to connect individuals, firms and organisations. Whether this will actually lead to the integration of markets and societies is a different issue. The articles collected in this book shed light on crucial considerations for the success of global communication networks. These include frameworks for regulation, inclusion of customers in defining product and service strategies, access to advanced technology and networks for all groups, and more.
The symposium on "Worldwide Advances in Communications Networks" which was held on May 14-15, 1992 at GMU was an ambitious attempt to bring together leaders in the communications area to discuss the major issues in this rapidly-changing technology. The symposium was a success and many of the ideas presented at the conference are being implemented. This proceeding contains the majority of the papers presented at the symposium and abstracts of the remainder. The papers may be divided into seven general categories. The first five papers explore some important design issues for high speed networks (gigabit networks). Traffic modelling, quality of service guarantees, switching alternatives, and r...
In this text, the authors develop a multitheoretical model that relates different social science theories with different network properties. This model is multilevel, providing a network decomposition that applies the various social theories to all network levels.
This guide highlights the three most critical success factors of network management, including its functions, instruments, and human resource skills, showing how to avoid errors and successfully manage communication networks. The guide describes how to use the connectivity and manageability components of a network to improve system efficiency, integrity, and security. It explores the performance impact of network components, offers a state-of-the-art review of propriety, de facto, and standard architectures, and illustrates three classes of network management tools, explaining how to choose among them and implement them for optimum data output.
