  • End-to-End Quality of Service Mechanisms in Next Generation Heterogeneous Networks

    • Authors: Abdelhamid Mellouk (2009)

  • This book presents and explains all the techniques in new generation networks which integrate efficient global control mechanisms in two directions: (1) maintain QoS requirements in order to maximize network resources utilization, and minimize operational costs on all the types of wired-wireless-mobile networks used to transport traffic, and (2) mix the QoS associated with home, access, and core networks in order to provide Quality of Service/Quality of Experience expected by users of new services. Communication between various devices makes it possible to provide unique and innovative services. Although ad hoc systems are very powerful mechanisms, they are also quite complex. This masterful resource demystifies these complexities with detailed accounts of the technologies, applicat...

  • Cognitive radio networks

    • Authors: Kwang-Cheng Chen (2009)

  • Giving a basic overview of the technologies supporting cognitive radio this introductory-level text follows a logical approach, starting with the physical layer and concluding with applications and general issues. It provides a background to advances in the field of cognitive radios and a new exploration of how these radios can work together as a network.

  • Introduction to Network Simulator NS2

    • Authors: Issariyakul, Teerawat (2009)

  • An Introduction to Network Simulator NS2 is a beginners' guide for network simulator NS2, an open-source discrete event simulator designed mainly for networking research. NS2 has been widely accepted as a reliable simulation tool for computer communication networks both in academia and industry. This book will present two fundamental NS2 concepts:i) how objects (e.g., nodes, links, queues, etc.) are assembled to create a network and ii) how a packet flows from one object to another

  • Linear and nonlinear optimization

    • Authors: Igor Griva (2009)

  • Provides an introduction to the applications, theory, and algorithms of linear and nonlinear optimization. The emphasis is on practical aspects - discussing modern algorithms, as well as the influence of theory on the interpretation of solutions or on the design of software. The book includes several examples of realistic optimization models that address important applications. The succinct style of this second edition is punctuated with numerous real-life examples and exercises, and the authors include accessible explanations of topics that are not often mentioned in textbooks, such as duality in nonlinear optimization, primal-dual methods for nonlinear optimization, filter methods, and applications such as support-vector machines. The book is designed to be flexible. It has a modu...

  • Agile web development with rails

    • Authors: Sam Ruby (2009)

  • With this book, you'll learn how to use ActiveRecord to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. Need to create and modify your schema? Migrations make it painless (and they're versioned, so you can roll changes backward and forward). You'll learn how to use the Action Pack framework to route incoming requests and render pages using easy-to-write templates and components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There is extensive coverage of testing, and the rewritten Deployment chapter now covers Phusion Passenger.

  • Complex variables and applications

    • Authors: James Ward Brown (2009)

  • This text serves as an introductory course in the theory and application of functions of a complex variable. The text is designed to develop the theory that is prominent in applications of the subject. Readers will find a special emphasis given to the application of residues and conformal mappings.
