شبکه‌سازی مش بی‌سیم: معماری‌ها، پروتکل‌ها و استانداردها

This is the first book to provide readers a comprehensive technical guide covering recent and open issues in wireless mesh networks. Wireless Mesh Networking: Architectures, Protocols and Standards explores the various key challenges in diverse scenarios as well as emerging standards, including capacity and scalability. It focuses on concepts, effective protocols proposals, system integration, performance analysis techniques, simulation, experiments, and future research directions. It contains illustrative figures and allows for complete cross-referencing. It also details information on the particular techniques for efficiently improving the mesh network performance.

Wireless mesh networking is a new technology that has the potential to revolutionize how we access the Internet and communicate with co-workers and friends. Wireless Mesh Networks examines the concept and explores its advantages over existing technologies. This book explores existing and future applications, and examines how some of the networking protocols operate.

The text offers a detailed analysis of the significant problems affecting wireless mesh networking, including network scale issues, security, and radio frequency interference, and suggests actual and potential solutions for each problem.

Although the book's primary focus is the potential use of wireless mesh networks in the commercial marketplace, it enables readers to gain an appreciation for use of the technology in the office, at government agencies, on campus, and in the home.

This book is intended as a text for a one- or two- semester undergraduate introductory course in probability, statistics, and reliability with an emphasis on applications. The authors state that Probability, Statistics, and Reliability for Engineers was developed with an emphasis on engineering and technological problems.....and is intended to better prepare future engineers, as well as assist practicing engineers, in understanding the fundamentals of probability, statistics, and reliability methods, especially thier applications, limitations, and potentials.

Overall, Probability, Statistics, and Reliability for Engineers does a good job presenting real-life examples to illustrate each new concept, but not enough basic, nonapplied examples are given and absolutely no theory is presented to support any of the concepts introduced. It is my opinion that the reader would need prior exposure to statistical concepts in order to read, comprehend, and learn from this book.

Metro Service Providers are increasingly turning to Multi-Protocol Label Switching (MPLS) to converge disparate networks and services into a unified core, maintain quality, and deliver additional value-added capabilities. MPLS for Metropolitan Area Networks addresses service providers' challenges by demonstrating solutions provided by MPLS features such as traffic engineering (TE), fast reroute, VPNs, virtual private LAN services (VPLS), and QoS.

The text opens with an overview of metro networks and MPLS, describing business opportunities and challenges and how mission-critical applications can be deployed within Metropolitan Area Networks (MANs). It then examines traffic engineering issues, focusing on fundamental TE concepts, network control, trunk attributes, constraint-based routing (CBR), Resource Reservation Protocol with TE extensions (RSVP-TE), and resource optimization.

Following a discussion on how MPLS can bring increased reliability to MANs, the author then concludes the book with a detailed analysis of the service aspect of MANs. Topics reviewed include L3 and L2 MPLS VPNs, geographically dispersed Ethernet multipoint services, virtual private LAN services (VPLS), and the integrated services (IntServ) and differentiated services (DiffServ) QoS models with respect to MPLS.

The entire book adopts a simplify-and-exemplify approach, containing a series of real-life case studies and using representative topologies as a basis for illustrating the concepts discussed in each chapter. This learning-by-example approach helps you to remember and understand the complex MPLS concepts and technologies. You can then apply what you have learned from these examples and scenarios to your specific networking environments.

The DSL arena is expanding rapidly, making it highly unlikely that any single author can adequately address the breadth and depth of the subject. Responding to the demand of designers worldwide, Fundamentals of DSL Technology combines the strengths of the field's most renowned DSL experts, providing a foundation of all aspects of DSL system design.

The volume begins with an introductory three-chapter examination of DSL copper transmission channels, reviewing the basic telephone environment, the physical-layer twisted pair, and the noise environment in the twisted pair channel. The book then explores line codes - laying the foundation for later chapters about other aspects of DSL design - and discusses the basic objectives of DSL service, comparing DSL to other broadband delivery methods.

The book concludes with a description of other basic aspects of DSL transmission, covering topics such as trellis codes, Reed-Solomon codes and interleaving, turbo and LDPC codes, basic equalization theory, synchronization, and more.

Until now, developers and researchers interested in the design, operation, and performance of Bluetooth networks have lacked guidance about potential answers and the relative advantages and disadvantages of performance solutions.

Performance Modeling and Analysis of Bluetooth Networks: Polling, Scheduling, and Traffic Control summarizes the research on the performance of Bluetooth networks, including both piconets and scatternets, conducted since 2001. The book provides insights into the performance of Bluetooth networks through an analytical approach based upon queuing theory and discrete event simulation. It also proposes and validates solutions for common problems that are not covered by the official Bluetooth specifications.

This volume allows developers and researchers to enrich their knowledge of performance issues and become better equipped to solve problems related to the design, deployment, and operation of Bluetooth networks.
