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.

Available in PDF, EPUB and Kindle. Book excerpt: Network flow theory has been used across a number of disciplines, including theoretical computer science, operations research, and discrete math, to model not only problems in the transportation of goods and information, but also a wide range of applications from image segmentation problems in computer vision to deciding when a baseball team has been eliminated from contention. This graduate text and reference presents a succinct, unified view of a wide variety of efficient combinatorial algorithms for network flow problems, including many results not found in other books. It covers maximum flows, minimum-cost flows, generalized flows, multicommodity flows, and global minimum cuts and also presents recent work on computing electrical flows along with recent applications of these flows to classical problems in network flow theory.

Gangammanavar and published by . This book was released on 2009 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Wireless networks are increasingly used to carry applications with QoS constraints. While dealing with such applications the problem of admission control arise, which consist of determining whether it is possible to fulfill the demands of the set of clients. The other problem is to find an optimal scheduling policy to meet the demands of all the clients. In this work we try to jointly address the the quality of service criteria of per packet delay and delivery ratio for a client in an unreliable wireless broadcast setting. A key setup to compare different transmission strategies in a cellular downlink is provided. We formulate the problem as an optimization problem with the objective of achieving the quality metric for each of the flows in the long run. The packets are considered to have a strict deadline whose information is available to the server. Primal- Dual method is adapted to solve the optimization problem. A joint rate control and resource allocation algorithm is established. Dynamic programming recursions are used to implement the resource allocation algorithm. Insights into serving different per-packet deadlines and early decodability option have also been provided.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Integrated Methods for Optimization was published in January 2007. Because the book covers a rapidly developing field, the time is right for a second edition. The book provides a unified treatment of optimization methods. It brings ideas from mathematical programming (MP), constraint programming (CP), and global optimization (GO)into a single volume. There is no reason these must be learned as separate fields, as they normally are, and there are three reasons they should be studied together. (1) There is much in common among them intellectually, and to a large degree they can be understood as special cases of a single underlying solution technology. (2) A growing literature reports how they can be profitably integrated to formulate and solve a wide range of problems. (3) Several software packages now incorporate techniques from two or more of these fields. The book provides a unique resource for graduate students and practitioners who want a well-rounded background in optimization methods within a single course of study. Engineering students are a particularly large potential audience, because engineering optimization problems often benefit from a combined approach—particularly where design, scheduling, or logistics are involved. The text is also of value to those studying operations research, because their educational programs rarely cover CP, and to those studying computer science and artificial intelligence (AI), because their curric ula typically omit MP and GO. The text is also useful for practitioners in any of these areas who want to learn about another, because it provides a more concise and accessible treatment than other texts. The book can cover so wide a range of material because it focuses on ideas that arerelevant to the methods used in general-purpose optimization and constraint solvers. The book focuses on ideas behind the methods that have proved useful in general-purpose optimization and constraint solvers, as well as integrated solvers of the present and foreseeable future. The second edition updates results in this area and includes several major new topics: Background material in linear, nonlinear, and dynamic programming. Network flow theory, due to its importance in filtering algorithms. A chapter on generalized duality theory that more explicitly develops a unifying primal-dual algorithmic structure for optimization methods. An extensive survey of search methods from both MP and AI, using the primal-dual framework as an organizing principle. Coverage of several additional global constraints used in CP solvers. The book continues to focus on exact as opposed to heuristic methods. It is possible to bring heuristic methods into the unifying scheme described in the book, and the new edition will retain the brief discussion of how this might be done.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published as a special issue of the Creativity Research Journal, this volume gives a balanced and reflective account of the challenges and opportunities of technology-enabled creative learning in contemporary societies. Providing a current and updated account of the challenges posed by the Coronavirus to online education, chapters more broadly offer conceptual reflections and empirically informed insights into the impact of technology on individual and collective creativity and learning. These thoughts are explored in relation to school achievement, the development of digital educational resources, online collaboration, and virtual working. Further, the book also considers how the creative use of technology poses risks to learning through the accidental or deliberate dissemination of misinformation, and online manipulation of common societal values in the era of COVID-19. Creative Learning in Digital and Virtual Environments looks at the connection between creativity, learning, and school achievement, and analyses the impact of virtual environments on creative expression. It will appeal to postgraduate students in the fields of creativity and learning, as well as to students and academics involved with broader research in areas such as the role of technology in education, e-Learning and distance education. Vlad P. Glăveanu is Associate Professor and Head of the Department of Psychology and Counselling at Webster University Geneva, Switzerland, as well as Associate Professor II at the University of Bergen, Norway. Ingunn Johanne Ness is a Senior Researcher at the Centre for the Science of Learning & Technology, University of Bergen, Norway.
