Book Description
This Synthesis Lecture presents a discussion of Quality of Service (QoS) in wireless networks over unlicensed spectrum. The topic is presented from the point of view of protocols for wireless networks (e.g., 802.11) rather than the physical layer point of view usually discussed for cellular networks in the licensed wireless spectrum. A large number of mobile multimedia wireless applications are being deployed over WiFi (IEEE 802.11) and Bluetooth wireless networks and the number will increase in the future as more phones, tablets, and laptops are equipped with these unlicensed spectrum wireless interfaces. Achieving QoS objectives in wireless networks is challenging due to limited wireless resources, wireless nodes interference, wireless shared media, node mobility, and diverse topologies. The author presents the QoS problem as (1) an optimization problem with different constraints coming from the interference, mobility, and wireless resource constraints and (2) an algorithmic problem with fundamental algorithmic functions within wireless resource management and protocols. Table of Contents: Preface / Basics of Quality of Service in Wireless Networks / QoS-Aware Resource Allocation / Bandwidth Management / Delay Management / Routing / Acknowledgment / References / Author Biography

Book Description
The goal of Unlicensed Mobile Access (UMA) is to provide seamless access to GSM and GPRS mobile service networks via unlicensed spectrum technologies, including Bluetooth, WiMAX, and Wi-Fi. Expanding on the level of knowledge in this growing field, Unlicensed Mobile Access Technology: Protocols, Architectures, Security, Standards, and Applications presents the first complete cross-referenced resource exploring UMA and UMA-relevant technologies. When operating successfully, the technology supporting dual-mode enabled mobile terminals allows subscribers to roam freely and seamlessly between cellular networks. However, various technical challenges still occasionally impede clear communication. This book explores the complex issue of mobility management and emphasizes the need for intelligently designed vertical and horizontal handoff algorithms that will improve adaptability in heterogeneous wireless environments. In addition, it reviews the various strategies to guarantee Quality-of-Service (QoS) during movement and handoff. The first chapters introduce the basic technology of these systems and discuss QoS, resource management, mobility management, and security issues in UMA technology. The middle section concentrates on protocols and security challenges in UMA-related technologies, which include Bluetooth, WirelessPAN, Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.16). The final chapters present standard specifications and various applications. Comprised of contributions from world-wide experts, this book is a complete reference, offering guidance on all aspects of the technical and practical issues in UMA technology.

Book Description
Spectrum Sharing in Wireless Networks: Fairness, Efficiency, and Security provides a broad overview of wireless network spectrum sharing in seven distinct sections: The first section examines the big picture and basic principles, explaining the concepts of spectrum sharing, hardware/software function requirements for efficient sharing, and future trends of sharing strategies. The second section contains more than 10 chapters that discuss differing approaches to efficient spectrum sharing. The authors introduce a new coexistence and sharing scheme for multi-hop networks, describe the space-time sharing concept, introduce LTE-U, and examine sharing in broadcast and unicast environments. They then talk about different cooperation strategies to achieve mutual benefits for primary users (PU) and secondary users (SU), discuss protocols in a spectrum sharing context, and provide different game theory models between PUs and SUs. The third section explains how to model the interactions of PUs and SUs, using an efficient calculation method to determine spectrum availability. Additionally, this section explains how to use scheduling models to achieve efficient SU traffic delivery. The subject of the fourth section is MIMO-oriented design. It focuses on how directional antennas and MIMO antennas greatly enhance wireless network performance. The authors include a few chapters on capacity/rate calculations as well as beamforming issues under MIMO antennas. Power control is covered in the fifth section which also describes the interference-aware power allocation schemes among cognitive radio users and the power control schemes in cognitive radios. The sixth section provides a comprehensive look at security issues, including different types of spectrum sharing attacks and threats as well as corresponding countermeasure schemes. The seventh and final section covers issues pertaining to military applications and examines how the military task protects its data flows when sharing the spectrum with civilian applications.

Book Description
Mobile communications and next generation wireless networks emerge as new distribution channels for the media. This development offers exciting new opportunities for media companies: the mobile communication system creates new usage contexts for media content and services; the social use of mobile communications suggests that identity representation in social networks, impulsive access to trusted media brands, and micro-coordination emerge as new sources of value creation in the media industries. In the light of this background, this book takes two different viewpoints on the development of mobile media: from a competitive strategy point of view it analyzes the extension of cross-media strategies and the emergence of cross-network strategies; from a public policy point of view it develops demands and requirements for an innovation policy that fosters innovation in mobile media markets.
