Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this study is to develop useful Genetic Algorithm (GA) models to solve two telecommunication network design problems: degree-constrained minimum spanning tree (DCMST) and Steiner-tree star (STS) in digital data service (DDS). The thesis is divided into three major parts. First, a review of general network design problems is presented, followed by a review of general GA model and its current applications in the network design problem. In the second part, we propose a revised mathematical programming model of DCMST. To consider both upper and lower degree constraints for each node, a hybrid GA model was then developed to solve the problem. The mathematical formulation was enhanced to improve the fault-tolerance problem in traditional DCMST.

Available in PDF, EPUB and Kindle. Book excerpt: The development of efficient provisioning methods is one of the remaining challenges for the successful deployment of telecommunication networks. In this thesis, two of the many problems involved in telecommunication networks design are addressed: the connection admission control problem (CAC), which refers to the set of actions, taken at connection time, to decide whether to accept or reject the request for a new call/connection. The second is the network-wide link sizing problem, which selects the topology of the (ideally) optimal network interconnecting the nodes, based on traffic characterization, nodal layout, routing and admission control procedures. These two problems are related since the CAC policy, together with the traffic characterization, nodal layout and routing, determines the internal traffic of the network which is used in the link sizing problem. Two location models for the design of telecommunications networks, with constrained buffer length at switches, are introduced and discussed, which find optimal locations of switches on a network, and allocate users to them so as to minimize overall cost. Also, for a given buffer length, the models keep the desired cell-loss probability P smaller than or equal to alpha. Four fault tolerant telecommunication networks design models are discussed. Relaxation techniques and heuristics are used to solve the models. The fundamental network design problem that is addressed consists in determining, given the location of the communication nodes, the traffic demands among pairs of origin-destination nodes, fault tolerance restrictions and the cost structure for the available technologies, the capacity to be assigned to each link, in such a way to satisfy the restriction while reaching a minimum cost network. The thesis also focuses on the use of genetic algorithms in the design of telecommunications networks satisfying bi-connectivity and delay constraints. The design of a biconnected telecommunication network, consists in the interconnection of a set of N nodes, in such a way there exist at least two alternative paths between any given pair of nodes and the cost of the network (considering routing, capacities and delay restrictions) is minimized. An admission control and a traffic shaping method for BISDN/ATM networks are proposed. The method operates at the burst connection level based on the Sustainable data-transfer rate concept. The model treats all cells equally regardless of their associated service requirements.

This book was released on 2014-08-09 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing complexity of telecommunication networks requires us to develop adequate mathematical models. We must find their characteristics, optimize them subject to chosen criteria, and develop the corresponding control algorithms. Multidimensional queueing models are used to design and optimize modern and next-generation networks (NGN). The central problem of the related mathematical theory is to apply multidimensional and large-size queueing models to improve efficiency. In this book new methods are successively developed and applied to solve related problems. The book is recommended for researchers engaged with the mathematical theory of telecommunications traffic.

Available in PDF, EPUB and Kindle. Book excerpt: This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design. These points are equally relevant and applicable in today’s world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.

Download or read book Optimization of Computer Networks written by Pablo Pavón Mariño and published by John Wiley & Sons. This book was released on 2016-03-28 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the design and optimization of computer networks applying a rigorous optimization methodology, applicable to any network technology. It is organized into two parts. In Part 1 the reader will learn how to model network problems appearing in computer networks as optimization programs, and use optimization theory to give insights on them. Four problem types are addressed systematically – traffic routing, capacity dimensioning, congestion control and topology design. Part 2 targets the design of algorithms that solve network problems like the ones modeled in Part 1. Two main approaches are addressed – gradient-like algorithms inspiring distributed network protocols that dynamically adapt to the network, or cross-layer schemes that coordinate the cooperation among protocols; and those focusing on the design of heuristic algorithms for long term static network design and planning problems. Following a hands-on approach, the reader will have access to a large set of examples in real-life technologies like IP, wireless and optical networks. Implementations of models and algorithms will be available in the open-source Net2Plan tool from which the user will be able to see how the lessons learned take real form in algorithms, and reuse or execute them to obtain numerical solutions. An accompanying link to the author’s own Net2plan software enables readers to produce numerical solutions to a multitude of real-life problems in computer networks (www.net2plan.com).

Download or read book Regional Failure Events in Communication Networks written by Balázs Vass and published by Springer Nature. This book was released on 2022-08-31 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive study covering the design and application of models and algorithms for assessing the joint device failures of telecommunication backbone networks caused by large-scale regional disasters. At first, failure models are developed to make use of the best data available; in turn, a set of fast algorithms for determining the resulting failure lists are described; further, a theoretical analysis of the complexity of the algorithms and the properties of the failure lists is presented, and relevant practical case studies are investigated. Merging concepts and tools from complexity theory, combinatorial and computational geometry, and probability theory, a comprehensive set of models is developed for translating the disaster hazard in informative yet concise data structures. The information available on the network topology and the disaster hazard is then used to calculate the possible (probabilistic) network failures. The resulting sets of resources that are expected to break down simultaneously are modeled as a collection of Shared Risk Link Groups (SRLGs), or Probabilistic SRLGs. Overall, this book presents improved theoretical methods that can help predicting disaster-caused network malfunctions, identifying vulnerable regions, and assessing precisely the availability of internet services, among other applications.

Available in PDF, EPUB and Kindle. Book excerpt: Combinatorial optimization is a fascinating topic. Combinatorial optimization problems arise in a wide variety of important fields such as transportation, telecommunications, computer networking, location, planning, distribution problems, etc. Important and significant results have been obtained on the theory, algorithms and applications over the last few decades. In combinatorial optimization, many network design problems can be generalized in a natural way by considering a related problem on a clustered graph, where the original problem's feasibility constraints are expressed in terms of the clusters, i.e., node sets instead of individual nodes. This class of problems is usually referred to as generalized network design problems (GNDPs) or generalized combinatorial optimization problems. The express purpose of this monograph is to describe a series of mathematical models, methods, propositions, algorithms developed in the last years on generalized network design problems in a unified manner. The book consists of seven chapters, where in addition to an introductory chapter, the following generalized network design problems are formulated and examined: the generalized minimum spanning tree problem, the generalized traveling salesman problem, the railway traveling salesman problem, the generalized vehicle routing problem, the generalized fixed-charge network design problem and the generalized minimum vertex-biconnected network problem. The book will be useful for researchers, practitioners, and graduate students in operations research, optimization, applied mathematics and computer science. Due to the substantial practical importance of some presented problems, researchers in other areas will find this book useful, too.

Available in PDF, EPUB and Kindle. Book excerpt: For the first time the problems of voice services self-similarity are discussed systematically and in detail with specific examples and illustrations. Self-Similar Processes in Telecommunications considers the self-similar (fractal and multifractal) models of telecommunication traffic and efficiency based on the assumption that its traffic has fractal or multifractal properties (is self-similar). The theoretical aspects of the most well-known traffic models demonstrating self-similar properties are discussed in detail and the comparative analysis of the different models’ efficiency for self-similar traffic is presented. This book demonstrates how to use self-similar processes for designing new telecommunications systems and optimizing existing networks so as to achieve maximum efficiency and serviceability. The approach is rooted in theory, describing the algorithms (the logical arithmetical or computational procedures that define how a task is performed) for modeling these self-similar processes. However, the language and ideas are essentially accessible for those who have a general knowledge of the subject area and the advice is highly practical: all models, problems and solutions are illustrated throughout using numerous real-world examples. Adopts a detailed, theoretical, yet broad-based and practical mathematical approach for designing and operating numerous types of telecommunications systems and networks so as to achieve maximum efficiency Places the subject in context, describing the current algorithms that make up the fractal or self-similar processes while pointing to the future development of the technology Offers a comparative analysis of the different types of self-similar process usage within the context of local area networks, wide area networks and in the modeling of video traffic and mobile communications networks Describes how mathematical models are used as a basis for building numerous types of network, including voice, audio, data, video, multimedia services and IP (Internet Protocol) telephony The book will appeal to the wide range of specialists dealing with the design and exploitation of telecommunication systems.
