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 2015 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dramatic increase in wireless applications resulted in exponential data growth as well as significant energy demands. In this work, we focus on developing techniques and technologies that can supply high data rate with minimal power consumption requirements. First, we study the problem of simultaneous information and power transfer in a wireless multi-user, single hop network. Specifically, we develop an optimal resource allocation algorithm that maximizes the long term average rate of the network while harvesting energy from both the received signal and the interference. We focus on receivers that split the received signal power into two streams; one is fed to an information decoding block and the other is fed to an energy harvester block. We use a weight perturbation Lyapunov approach to optimally schedule data admission and allocate the powers and the energy splitting factors. We show that the designed algorithm achieves O(1/K) of the optimal and requires O(K) data queue and battery size. Then we study the potential as well as different challenges facing the millimeter wave technology. We focus on the problem of detecting and tracking the receiver location. We also address the problem of high power consumption at the receiver. We start by doing measurements on the millimeter wave channel and investigate its correlation with regular radio frequency channel. We develop an algorithm for discovering the receiver location and the underlying situation of the channel with low overhead and power consumption. A resource allocation algorithm is developed to optimize the network data rate while maintaining a minimal power consumption at the receiver.

This book was released on 2017-08-18 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth discussion on how to efficiently manage resources of heterogeneous wireless networks and how to design resource allocation algorithms to suit real world conditions. Efficiently managing resources of the networks is more crucial now, than ever before, to meet users’ rapidly increasing demand for higher data rates, better quality-of-service (QoS) and seamless coverage. Some of the techniques that can be incorporated within heterogeneous wireless networks to achieve this objective are interworking of the networks, user multi-homing and device-to-device (D2D) communication. Designing resource allocation algorithms to suit real world conditions is also important, as the algorithms should be deployable and perform well in real networks. For example, two of the conditions considered in this book are resource allocation intervals of different networks are different and small cell base stations have limited computational capacity. To address the first condition, resource allocation algorithms for interworking systems are designed to allocate resources of different networks at different time-scales. To address the second condition, resource allocation algorithms are designed to be able to run at cloud computing servers. More of such conditions, algorithms designed to suit these conditions, modeling techniques for various networks and performance analysis of the algorithms are discussed in the book. This book concludes with a discussion on the future research directions on the related fields of study. Advanced-level students focused on communication and networking will use this book as a study guide. Researchers and experts in the fields of networking, converged networks, small-cell networks, resource management, and interference management, as well as consultants working in network planning and optimization and managers, executives and network architects working in the networking industry will also find this book useful as a reference.
Download or read book Performance Analysis of Multihop Ad Hoc and Hybrid Wireless Networks written by Hrishikesh Venkataraman and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multihop mobile wireless networks is a subject of intense research interest for next generation wireless systems. As we move towards fourth generation (4G) networks, high data-rates of the order of 100 Mbps can be achieved only over short distances. A multihop network has smaller transmission distance as compared to an equivalent single-hop network. This enables the radio terminals that are spatially well-separated from each other to reuse the same resources when the resulting interferences are not too severe. In this dissertation, the multihop network design is studied for two different kinds of systems: multihop ad hoc network and multihop hybrid cellular network. In the first part of the thesis work, a multihop ad hoc network is analyzed in detail and the system capacity is computed. However, the calculation of optimal resource allocation that would maximize the system capacity is found to be an NP-hard problem. Considering this complexity, a random data hopping technique has been proposed over a time-slot (TS) partitioned system in order to improve the system capacity of the network. It has been found that the granularity of the TS(s) can be increased by reducing the duration of each TS. Significantly, applying the random data hoping technique over the TS partitioned system results in an increase in the system capacity without any additional increase in the computational complexity. In the second part of the thesis work, a multihop hybrid cellular network is studied. It is known that optimal resource allocation in a multihop cellular network is again a NP-hard problem. A novel cluster-based design is proposed in this work for a 2-hop cellular network, whereby, two pairs communicate simultaneously in every hexagonal cell, at any time instant. Such a cluster-based 2-hop design provides an increase in the spatial resource reuse and hence results in a much higher system capacity as compared to three standard benchmark algorithms for 2-hop cellular networks.

Available in PDF, EPUB and Kindle. Book excerpt: The last decade has seen an unprecedented growth in the demand for wireless services. These services are fueled by applications that often require not only high data rates, but also very low latency to function as desired. However, as wireless networks grow and support increasingly large numbers of users, these control algorithms must also incur only low complexity in order to be implemented in practice. Therefore, there is a pressing need to develop wireless control algorithms that can achieve both high throughput and low delay, but with low-complexity operations. While these three performance metrics, i.e., throughput, delay, and complexity, are widely acknowledged as being among the most important for modern wireless networks, existing approaches often have had to sacrifice a subset of them in order to optimize the others, leading to wireless resource allocation algorithms that either suffer poor performance or are difficult to implement. In contrast, the recent results presented in this book demonstrate that, by cleverly taking advantage of multiple physical or virtual channels, one can develop new low-complexity algorithms that attain both provably high throughput and provably low delay. The book covers both the intra-cell and network-wide settings. In each case, after the pitfalls of existing approaches are examined, new systematic methodologies are provided to develop algorithms that perform provably well in all three dimensions.
Download or read book Robust Resource Allocation in Future Wireless Networks written by Saeedeh Parsaeefard and published by Springer. This book was released on 2017-03-06 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art research on robust resource allocation in current and future wireless networks. The authors describe the nominal resource allocation problems in wireless networks and explain why introducing robustness in such networks is desirable. Then, depending on the objectives of the problem, namely maximizing the social utility or the per-user utility, cooperative or competitive approaches are explained and their corresponding robust problems are considered in detail. For each approach, the costs and benefits of robust schemes are discussed and the algorithms for reducing their costs and improving their benefits are presented. Considering the fact that such problems are inherently non-convex and intractable, a taxonomy of different relaxation techniques is presented, and applications of such techniques are shown via several examples throughout the book. Finally, the authors argue that resource allocation continues to be an important issue in future wireless networks, and propose specific problems for future research.
