Download or read book Telecommunications Planning written by S. Raghavan and published by Springer Science & Business Media. This book was released on 2006-03-12 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book serves as a companion volume to the Seventh INFORMS Telecommunications Conference held in Boca Raton, Florida, March 7-10, 2004. The 18 papers in this book were carefully selected after a thorough re view process. The research presented within these articles focuses on the latest methodological developments in three key areas—pricing of telecommunica tions services, network design, and resource allocation—that are most relevant to current telecommunications planning. With the global deregulation of the telecommunications industry, effective pricing and revenue management, as well as an understanding of competi tive pressures are key factors that will improve revenue in telecommunica tions companies. Chapters 1-5 address these topics by focusing on pricing of telecommunications services. They present some novel ideas related to pricing (including auction-based pricing of network bandwidth) and modeling compe tition in the industry. The successful telecommunications companies of the future will likely be the ones that can minimize their costs while meeting customer expectations. In this context the optimal design/provisioning of telecommunication networks plays an important role. Chapters 6-12 address these topics by focusing on net work design for a wide range of technologies including SONET, SDH, WDM, and MPLS. They include the latest research developments related to the mod eling and solving of network design problems. Day-to-day management/control of telecommunications networks is depen dent upon the optimal allocation of resources. Chapters 13-18 provide insight ful solutions to several intriguing resource allocation problems.

Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure networks to transport material, energy, and information are critical for today's interconnected economies and communities, and network disruptions and failures can have serious economic and even catastrophic consequences. Since these networks require enormous investments, network service providers emphasize both survivability and cost-effectiveness in their network design decisions. This paper addresses the survivable network design problem, a core model to address the cost and redundancy tradeoffs facing network planners. Using a novel connectivity upgrading strategy, we develop several families of inequalities to strengthen a multi-commodity flow-based formulation for the problem. By raising the linear programming lower bound, these inequalities not only provide better performance guarantees for heuristic solutions but also accelerate exact solution methods and improve heuristic performance. We propose a heuristic strategy that iteratively rounds the fractional values, starting with the linear programming solution to our strong model. Extensive computational tests confirm that the valid inequalities, cutting plane algorithm, and heuristic procedure are very effective, and their performance is robust to changes in the network dimensions and desired connectivity structure. Our solution approach generates tight lower and upper bounds that are less than 0.7% apart on average.

Available in PDF, EPUB and Kindle. Book excerpt: The problem of designing a cost-efficient network that survives the failure of one or more nodes or edges of the network is critical to modern telecommunications engineering. The method developed in this book is designed to solve such problems to optimality. In particular, a cutting plane approach is described, based on polyhedral combinatorics, that is ableto solve real-world problems of this type in short computation time. These results are of interest for practitioners in the area of communication network design. The book is addressed especially to the combinatorial optimization community, but also to those who want to learn polyhedral methods. In addition, interesting new research problemsare formulated.

Download or read book Survivable Network Design Problems with High Connectivity Requirement written by Ibrahima Diarrassouba and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Network survivability is one of the key issue when designing a network. It has a crucial importance, especially for telecommunication networks, since a very large part of the economical activities uses telecommunication infrastructures. The aim of network engineers is hence to ensure both survivability, by satisfying some connectivity requirements, and quality of service (QoS). In this book, we propose a mathematical analysis of the problem of designing a minimum cost survivable and QoS-constrained network, where a high level of connectivity is required and QoS is guarantied by limiting the number of hop in each traffic path. We present Linear Programming models for the problem in different cases and investigate their polyhedral structure. All along this book, we address both theoretical and algorithmic aspects of the different cases we study, and develop efficient and exact algorithms to solve this network design problem. This book should be useful to practioners in telecommunications and network engineering, and to researchers and students who are interested in studying network design problems.

Download or read book The Sharpest Cut written by Martin Groetschel and published by SIAM. This book was released on 2004-01-01 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title is written in honor of Manfred Padberg, who has made fundamental contributions to both the theoretical and computational sides of integer programming and combinatorial optimization. This outstanding collection presents recent results in these areas that are closely connected to Padberg's research. His deep commitment to the geometrical approach to combinatorial optimization can be felt throughout this volume; his search for increasingly better and computationally efficient cutting planes gave rise to its title. The peer-reviewed papers contained here are based on invited lectures given at a workshop held in October 2001 to celebrate Padberg's 60th birthday. Grouped by topic (packing, stable sets, and perfect graphs; polyhedral combinatorics; general polytopes; semidefinite programming; computation), many of the papers set out to solve challenges set forth in Padberg's work. The book also shows how Padberg's ideas on cutting planes have influenced modern commercial optimization software.
Download or read book A Survivable and Reliable Network Topological Design Model written by Pablo Sartor and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is focused on the resolution of a mixed model for the design of large-sized networks. An algorithm is introduced, whose initial outcomes are promising in terms of topological robustness regarding connectivity and reliability. The algorithm combines the network survivability and the network reliability approaches. The problem of the topological design has been modeled based on the generalized Steiner problem with node-connectivity constraints (GSPNC), which is NP-hard. The aim of this study is to heuristically solve the GSP-NC model by designing low-cost highly connected topologies and to measure the reliability of such solutions with respect to a certain prefixed lower threshold. This research introduces a greedy randomized algorithm for the construction of feasible solutions for the GSP-NC and a local search algorithm based on the variable neighborhood search (VNS) method, customized for the GSP-NC. In order to compute the built network reliabilities, this work adapts the recursive variance reduction (RVR) technique, as a simulation method since the exact evaluation of this measurement is also NP-hard. The experimental tests were performed over a wide set of testing cases, which contained heterogeneous topologies, including instances of more than 200 nodes. The computational results showed highly competitive execution times, achieving minimal local optimal solutions of good quality fulfilling the imposed survivability and reliability conditions.
