Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to understand how to utilize wireless channels in a fair and efficient manner within a multi-users communication environment. We start by exploring the allocation of a single wireless downlink fading channel among competing users. The allocation of a single uplink multiacccess fading channel is studied as well. With multiple parallel fading channels, a MAC protocol based on pricing is proposed to allocate network resource according to users' demand. We also investigate the use of parallel transmissions and redundant packets to reduce the file transmission delay. Specifically, we develop a novel auction-based algorithm to allow users to fairly compete for a downlink wireless fading channel. We first use the second-price auction mechanism whereby user bids for the channel, during each time-slot, based on the fade state of the channel, and the user that makes the highest bid wins use of the channel by paying the second highest bid. Under the assumption that each user has a limited budget for bidding, we show the existence of a Nash equilibrium strategy. And the Nash equilibrium leads to a unique allocation for certain channel state distribution. We also show that the Nash equilibrium strategy leads to an allocation that is pareto optimal. We also investigate the use of another auction mechanism, the all-pay auction, in allocating a single downlink channel. A unique Nash equilibrium is shown to exist. We also show that the Nash equilibrium strategy achieves a throughput allocation for each user that is proportional to the user's budget For the uplink of a wireless channel, we present a game-theoretical model of a wireless communication system with multiple competing users sharing a multiaccess fading channel. With a specified capture rule and a limited amount of energy available, a user opportunistically adjusts its transmission power based on its own channel state to maximize the user's own individual throughput. We derive an explicit form of the Nash equilibrium power allocation strategy. Furthermore, as the number of users in the system increases, the total system throughput obtained by using a Nash equilibrium strategy approaches the maximum attainable throughput. In a communication scenario where multiple users sharing a set of multiple parallel channels to communicate with multiple satellites, we propose a novel MAC protocol based on pricing that allocates network resources efficiently according to users' demand. We first characterize the Pareto efficient throughput region (i.e., the achievable throughput region). The equilibrium price, where satellite achieve its objective and users maximize their payoffs, is shown to exist and is unique. The resulting throughput at the equilibrium is shown to be Pareto efficient. Finally, we explore how a user can best utilize the available parallel channels to reduce the delay in sending a file to the base-station or satellite. We study the reduction of the file delay by adding redundant packets (i.e., coding). Our objective here is to characterize the delay and coding tradeoff in a single flow case. We also want to address the question whether coding will help to reduce delay if every user in the system decides to add redundancy for its file transmission.

Download or read book Dynamic Channel Allocation written by Andrew D. Kaminsky and published by . This book was released on 2003-09-01 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Channel Allocation (DCA) offers the possibility of capturing unused channel capacity by allocating unused resources between competing network nodes. This can reduce or possibly eliminate channels sitting idle while information awaits transmission. This holds potential for increasing throughput on bandwidth constrained networks. This thesis begins by examining channel allocation techniques currently used. Following this, a solution is proposed that utilizes two types of algorithms to dynamically allocate channels from which a computer simulation is devised. Upon gathering the results, an analysis is conducted and suggestions are given for future work in channel allocation. Chapter II discusses and compares fixed channel allocation with dynamic channel allocation. In addition, some of the algorithms used to achieve channel allocation are explored. This chapter also looks at techniques used, such as inverse multiplexing, time division multiplexed on demand, hybrid channel allocation in wireless networks, and Beowulf Ethernet channel bonding. The background information presented in this chapter gives an indication that channel allocation is still being examined and several implementations are proposed. Chapter III proposes a solution with two scheduling algorithms. One algorithm is a First Come First Serve, which gives all free dynamic channels to the first requesting fixed channel. The other algorithm is a Fair Distribution, which gives a portion of the free dynamic channels to the requesting fixed channels. A computer program is devised that simulates these algorithms, and the methods used in the program classes are described in this chapter. (27 tables, 19 figures, 38 refs.)

Download or read book Resource Allocation in Next Generation Wireless Networks written by Wayne Li and published by Nova Publishers. This book was released on 2006 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Next generation wireless and mobile communication systems are rapidly evolving to satisfy the demands of various network users. Due to the great success and enormous impact of IP networks, high-speed transmission is now possible for both indoor and outdoor wireless systems, internet access and web browsing have become the ruling paradigm for next generation system. It is envisioned that new generation wireless networks and hand-held terminals will support a wide variety of multimedia services such as multimedia web browsing, video and news on demand, mobile office system, stock market information, and so on, to mobile users anywhere, anytime in an uninterrupted and seamless way with low-powered handsets. The characteristics of wireless links, as well as the desire to maintain connectivity while on the move, offer significant challenges to provisioning quality of service and the related performance is of central interest. Since the resources (such as time, frequency and code) in the wireless segments of such networks are very limited, over-dimensioning the network resource is equivalent to poor capital investment, while congestion at busy hours could mean lost calls and lost revenues. It is therefore critical for wireless network designers to utilise these resources efficiently and effectively. In response to the above demand for next generation wireless and mobile communication systems, this book aims at providing a timely and concise reference of the current activities and findings in the relevant technical fields. The primary goal is to address the key technical issues pertaining to the integrated new systems and present novel technical contributions. The book contains 14 invited chapters from prominent researchers working in this area around the world.

This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of the Fourth Workshop on Multiaccess, Mobility and Teletraffic for Wireless Communications held in October 1998 in Washington, D.C. The focus of this workshop is to identify, present and discuss the theoretical and implementation issues critical to the design of wireless networks. To ensure proper network design and engineering, designers of wireless networks need to understand and address issues such as radio propagation, antenna, interference management, multiaccess, mobility, teletraffic, signalling and networking protocols. In fact, not only do these issues need to be understood and addressed, their interdependence and interactions also deserve to be examined closely. Therefore, the goal of this workshop is to present papers addressing these issues, with the hope of stimulating further collaboration among researchers of various disciplines in wireless communications. High-speed wireless networks such as wireless ATM and GSM with high-speed data services continue to attract much research and development efforts. The major challenges on the physical and link layers in these networks include radio design, interference management, resource allocation and multiaccess protocol. Several papers on these issues are presented here. As the availability of radio spectrum is limited, there is always a desire to ''maximize'' the spectral efficiency, for example, by diligent (and perhaps dynamic) re-use of frequency and cell layout, while guaranteeing a certain quality of service (QoS). A number of papers at this workshop address these topics.

Download or read book Game Theoretic Approaches for Spectrum Redistribution written by Fan Wu and published by Springer Science & Business Media. This book was released on 2014-02-15 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief examines issues of spectrum allocation for the limited resources of radio spectrum. It uses a game-theoretic perspective, in which the nodes in the wireless network are rational and always pursue their own objectives. It provides a systematic study of the approaches that can guarantee the system’s convergence at an equilibrium state, in which the system performance is optimal or sub-optimal. The author provides a short tutorial on game theory, explains game-theoretic channel allocation in clique and in multi-hop wireless networks and explores challenges in designing game-theoretic mechanisms for dynamic channel redistribution. Since designing a completely secure mechanism is extremely expensive or impossible in most of distributed autonomous systems, it is more beneficial to study misbehavior of the nodes and develop light-weighted game-theoretic channel allocation mechanisms. With a mix of theoretical and hands-on information, the brief traces the concepts of game theory, the current state of spectrum allocation in wireless networks and future competition for resources. Thorough yet accessible, the content is ideal for researchers and practitioners working on spectrum redistribution. It is also a helpful resource for researchers and advanced-level students interested in game theory and wireless communications.

This book was released on 2009-06-29 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide tools for a better understanding of the fundamental tradeo?s and interdependencies in wireless networks, with the goal of designing resource allocation strategies that exploit these int- dependencies to achieve signi?cant performance gains. Two facts prompted us to write it: First, future wireless applications will require a fundamental understanding of the design principles and control mechanisms in wireless networks. Second, the complexity of the network problems simply precludes the use of engineering common sense alone to identify good solutions, and so mathematics becomes the key avenue to cope with central technical problems in the design of wireless networks. In this book, two ?elds of mathematics play a central role: Perron-Frobenius theory for non-negative matrices and optimization theory. This book is a revised and expanded version of the research monograph “Resource Allocation in Wireless Networks” that was published as Lecture Notes in Computer Sciences (LNCS 4000) in 2006. Although the general structure has remained unchanged to a large extent, the book contains - merous additional results and more detailed discussion. For instance, there is a more extensive treatment of general nonnegative matrices and interf- ence functions that are described by an axiomatic model. Additional material on max-min fairness, proportional fairness, utility-based power control with QoS (quality of service) support and stochastic power control has been added.

This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rutgers University launched WINLAB in 1989, just as the communications industry, the Federal government, and the financial community in the United States, were waking up to the growing public appetite for wireless communications and to the shortage of technology to feed it. The secret was already out in Europe, where no fewer than three new cordless and cellular systems were progressing from drawing board to laboratory to factory to consumers. In July 1989, the FCC held a well-attended tutorial that turned into a debate over whether second generation British or Swedish technology held the key to mass-market personal communications. Many in the audience wondered whether United States technology was out of the picture. Technology uncertainties are more acute in wireless communications than in any other information service. For example multi-gigabit optical fiber communications have followed an orderly progression from basic science leading to technology, which in turn stimulated standards, and then commercial products. Eventually applications will be found and industry and society at large will reap the benefits. By contrast, the applications of wireless communications are apparent to an eager public. A large market exists but is held in check by a shortage of capacity. The demand has led the cellular industry to formulate standards for advanced systems before the technology is in place to implement them. Everyone holds their breath waiting to observe performance of the first products. Gaps in basic science add to the uncertainty and forestall the resolution of technological debates.
