Available in PDF, EPUB and Kindle. Book excerpt: Recently the number of applications in the Internet which use data broad-casts, such as pay-per-view services, has increased greatly. In broadcast scheduling one is interested in answering user requests in such services with as little bandwidth as possible by bundling the answers appropriately. Flows over time are an important notion arising in connection with various appli-cations in communication and transportation networks. One of the basic question here is how can demands in a given network be routed to their destinations as quickly as possible? Economic relationships in the Internet are of great interest, e.g., when investigating robustness issues. Since they are treated as trade secrets, it is a challenge to infer them form samples of routes taken by packets in the Internet. The author Alexander Hall gives intro-ductions and several novel results for these three problem areas. Some of the main results resolve the complexity of the major optimization problems encountered in the three areas. Thereby, important and in some cases long-standing open questions have been answered. From an algorithmic point of view, optimal and approximation algorithms for each of the three areas are proposed. This book is of interest to scientists in academia and industry working on research problems pertaining to communication and transportation net-works.

Book Synopsis Variational Inequalities and Network Equilibrium Problems by : F. Giannessi
Download or read book Variational Inequalities and Network Equilibrium Problems written by F. Giannessi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings forth a set of papers presented at the conference on "Varia tional Inequalities and network equilibrium problems", held in Erice at the "G. Stam pacchia" School of the "E. Majorana" Centre for Scientific Culture in the period 19~25 June 1994. The meeting was conceived to contribute to the exchange between Variational Analysis and equilibrium problems, especially those related to network design. Most of the approaches and viewpoints of these fields are present in the volume, both as concerns the theory and the applications of equilibrium problems to transportation, computer and electric networks, to market behavior, and to bi~level programming. Being convinced of the great importance of equilibrium problems as well as of their complexity, the organizers hope that the merging of points of view coming from differ ent fields will stimulate theoretical research and applications. In this context Variational and Quasi~Variational Inequalities have shown them selves to be very important models for equilibrium problems. As a consequence in the last two decades they have received a lot of attention both as to mathematical inves tigation and applications. The proof that the above mentioned equilibrium problems can be expressed, in terms of Variational or Quasi~Variational Inequalities also in the non~standard and non~symmetric cases, has been a crucial improvement.

Book Synopsis Achieving Optimal Schedule by Network Flow Techniques by : Xili Wan
Download or read book Achieving Optimal Schedule by Network Flow Techniques written by Xili Wan and published by . This book was released on 2015 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling plays an important role in protocol design and performance optimizations for wireless or wired networks. This dissertation studies how to achieve optimal performance for two fundamental scheduling problems using network flow techniques. The first problem is Maximum lifetime scheduling for roadside networks. In this problem, sensors are deployed along a road to monitor traffic activities. A set of sensors can form a network if their sensing ranges cover the entire road. Since battery-driven sensors have limited lifetime, we need to schedule each sensor between active and sleep modes such that active sensors form a network to monitor the road while sleeping sensors reserve their energy until their turns to become active. At that time, another sensor network is formed to continue to monitor the road. A challenging problem is how to achieve the optimal schedule that the road can be monitored by such sensing networks, one after the other continuously, for a longest time. The previous research only solved a simple case where all sensors are identical initially. This dissertation presents a network flow model to solve the general case where each sensor may have different initial energy. Furthermore this dissertation presents a novel technique to obtain optimal scheduling for the road surveillance problem with survivability k in which the road needs k independent networks to monitor in order to make sensing data reliable. Second, the problem is Maximum Traffic Time-slot Scheduling (MTTS) problem in SS/TDMA satellite systems. This is a historical scheduling problem proposed decades ago. A two-step approach was developed to solve it. However, the Incremental Time-slot Assignment (ITSA) Problem induced in this two-step approach was proved to be NP-hard, which makes the original MTTS problem seem to be NP-hard. In the past decades, the optimal solution of the MTTS problem remains open. In this dissertation, a preprocessing with network flow technique is developed to achieve the optimal scheduling, which optimally solves this open problem.
Book Synopsis Decision Analysis, Location Models, and Scheduling Problems by : H. A. Eiselt
Download or read book Decision Analysis, Location Models, and Scheduling Problems written by H. A. Eiselt and published by Springer Science & Business Media. This book was released on 2013-06-04 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide readers with an introduction to the fields of decision making, location analysis, and project and machine scheduling. The combination of these topics is not an accident: decision analysis can be used to investigate decision seenarios in general, location analysis is one of the prime examples of decision making on the strategic Ievel, project scheduling is typically concemed with decision making on the tactical Ievel, and machine scheduling deals with decision making on the operational Ievel. Some of the chapters were originally contributed by different authors, and we have made every attempt to unify the notation, style, and, most importantly, the Ievel of the exposition. Similar to our book on Integer Programming and Network Models (Eiselt and Sandblom, 2000), the emphasis of this volume is on models rather than solution methods. This is particularly important in a book that purports to promote the science of decision making. As such, advanced undergraduate and graduate students, as weil as practitioners, will find this volume beneficial. While different authors prefer different degrees of mathematical sophistication, we have made every possible attempt to unify the approaches, provide clear explanations, and make this volume accessible to as many readers as possible.

Book Synopsis Guide to Flow-Aware Networking by : Jerzy Domżał
Download or read book Guide to Flow-Aware Networking written by Jerzy Domżał and published by Springer Nature. This book was released on 2020-10-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a comprehensive view on Flow-Aware Networking. It starts with a brief overview of the known QoS architectures based on the concept of a flow. Then, the original FAN concept is presented, along with its variations proposed by the authors. The next chapter covers a very valuable feature of the FAN architecture, namely its ability to assure net neutrality. The chapters that follow will discuss, in detail, a variety of issues making the FAN concept implementable, including congestion control, fairness, resilience to failures, service differentiation and degradation. The final chapter presents the test implementation of the FAN router, including the environment used and performance tests. Chapters are supplemented with problems to solve, along with their solutions. The pedagogical character of the book is supported by a number of illustrative examples contained in most of the chapters. At the end of the book, a glossary of the key terms is included, along with a comprehensive bibliography. Flow-based traffic management is currently becoming a mainstream. There is plenty of Quality of Service (QoS) techniques based on flows. Software-Defined Networking with its dominant protocol OpenFlow also follows this trend. Flow-Aware Networking (FAN) is a promising QoS architecture. Information on FAN can be found in various research papers. It is, therefore highly scattered. This book gathers practically all relevant information regarding FAN and puts it together. Quality of Service assurance is one of the key challenges of today’s Internet. The existing approaches to provide QoS do not meet expectations of network operators, managers and users although numerous efforts in this area have been reported. One of the most promising concepts is the Flow-Aware Network (FAN). FAN can play a key role in assuring the net neutrality, smoothly combining interests of all the involved parties. The authors of the proposal have been involved in FAN research practically since its inception at the start of the 21st century. The book reports the wide experiences the authors accumulated in the subject area during the work on common FAN-related projects conducted with the team of James Roberts that proposed the original FAN concept as well as other leading research groups in Europe and the USA. One of the aims of the book is to accompany courses taught by the authors.

Book Synopsis Scheduling and Congestion Control for Wireless and Processing Networks by : Libin Jiang
Download or read book Scheduling and Congestion Control for Wireless and Processing Networks written by Libin Jiang and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we consider the problem of achieving the maximum throughput and utility in a class of networks with resource-sharing constraints. This is a classical problem of great importance. In the context of wireless networks, we first propose a fully distributed scheduling algorithm that achieves the maximum throughput. Inspired by CSMA (Carrier Sense Multiple Access), which is widely deployed in today's wireless networks, our algorithm is simple, asynchronous, and easy to implement. Second, using a novel maximal-entropy technique, we combine the CSMA scheduling algorithm with congestion control to approach the maximum utility. Also, we further show that CSMA scheduling is a modular MAC-layer algorithm that can work with other protocols in the transport layer and network layer. Third, for wireless networks where packet collisions are unavoidable, we establish a general analytical model and extend the above algorithms to that case. Stochastic Processing Networks (SPNs) model manufacturing, communication, and service systems. In manufacturing networks, for example, tasks require parts and resources to produce other parts. SPNs are more general than queueing networks and pose novel challenges to throughput-optimum scheduling. We proposes a "deficit maximum weight" (DMW) algorithm to achieve throughput optimality and maximize the net utility of the production in SPNs.
