The rapid growth in mobile communications has led to an increasing demand for wideband high data rate communications services. In recent years, the Distributed Antenna System (DAS) has emerged as a promising candidate beyond 3G and 4G mobile communications.Distributed Antenna Systems: Open Architecture for Future Wireless Communications is a comprehensive technical guide that covers the fundamental concepts, recent advances and open issues of the DAS. The topic is explored with various key challenges in diverse scenarios, including architecture, capacity, connectivity, scalability, medium access control, scheduling, dynamic channel assignment and cross-layer optimization.The primary focus of this book is the introduction of concepts, effective protocols, system integration, performance analysis techniques, simulations and experiments, and more importantly, future research directions in the DAS.The first part of the book introduces DAS fundamentals, including channel models and theoretical issues, examining the capacity of the DAS with different structures. Concentrating on the MAC and protocols for the DAS, the second part of the book includes information on distributed signal processing, optimal resource allocation, cooperative MAC protocols, cross layer design, and distributed organization. The third part presents case studies and applications of the DAS, including experiment, RF engineering, and applications.

Wireless mesh networks (WMN) encompass a new area of technology set to play an important role in the next generation wireless mobile networks. WMN is characterized by dynamic self-organization, self-configuration, and self-healing to enable flexible integration, quick deployment, easy maintenance, low costs, high scalability, and reliable services. To achieve these aims, security mechanisms are essential to ensure trusted on-going communications.Security in Wireless Mesh Networks explores key security challenges set in diverse scenarios, as well as emerging standards that include authentication, access control and authorization, attacks, privacy and trust, encryption, key management, identity management, DoS attacks, intrusion detection and prevention, secure routing, and security policies. The book also examines security mechanisms in IEEE 802.11, IEEE 802.15, IEEE 802.16, and IEEE 802.20 standards. In addition, it provides numerous case studies and applications to facilitate understanding. As a single, comprehensive guide to security-related issues in WMN, this book is an important resource to have if you are working on the design, selection, and implementation of wireless mesh networks and system components.

A promising new technology, wireless mesh networks are playing an increasingly important role in the future generations of wireless mobile networks. Characterized by dynamic self-organization, self-configuration, and self-healing to enable quick deployment, easy maintenance, low cost, high scalability, and reliable services, this technology is becoming a vital mode complementary to the infrastructure-based wireless networks.Wireless Mesh Networking: Architectures, Protocols and Standards is the first book to provide engineers, students, faculties, researchers, and designers with a comprehensive technical guide covering introductory concepts. It addresses advanced and open issues in wireless mesh networks and explores various key challenges and diverse scenarios as well as emerging standards such as those for capacity, scalability, extensibility, reliability, and cognition. It focuses on concepts, effective protocols, system integration, performance analysis techniques, simulation, experiments, and future research directions. This volume contains illustrative figures and allows for complete cross-referencing on routing, security, spectrum management, MAC, cross-layer optimization, load-balancing, multimedia communication, MIMO, and smart antenna, etc. It also details information on the particular techniques for efficiently improving the performance of a wireless mesh network.Presenting a solid introduction, Wireless Mesh Networking: Architectures, Protocols and Standards elucidates problems and challenges in designing wireless mesh networks.

Organized into three parts, Resource, Mobility, and Security Management in Wireless Networks and Mobile Communications examines the inherent constraint of limited bandwidth and unreliable time-varying physical link in the wireless system, discusses the demand to realize the service continuity in the single-hop or multi-hop wireless networks, and explores trusted communication in mobile computing scenarios.Focusing on the background, technique survey, protocol design, and analytical methods, the book discusses standards in 802.11x/3G/4G, HotSpot Wireless, Bluetooth sensor networks, and access control in wireless Ad Hoc networks. Other topics include call admission control (CAC), routing, multicast, medium access control (MAC), scheduling, bandwidth adaptation, handoff management, location management, network mobility, secure routing, key management, authentication, security, privacy, and performance simulation and analysis.This book is a comprehensive source of information on basic concepts, major issues, design approaches, future research directions, and the interaction between these components. With its broad coverage allowing for easy cross reference, the book also provides detailed techniques for eliminating bandwidth insufficiency, increasing location management performance, and decreasing the associated authentication traffic. Features: Offers competitive, self-contained information on resource, mobility, and security management in wireless networks Explains the interaction and coupling among the most important components in wireless networks Examines background, applications, and standard protocols Addresses challenges and solutions in key management of wireless sensor networks Covers how to provide effective and efficient authentication and key agreements for cellular access security
