This book aims to present implications for China's urban development through international comparison of urbanization process from the perspective of spatio-temporal pattern, driving factors, rural-urban interactions, development trends and economic-ecological-social synergic development. Followed the research hotspot of the international urban studies, this book identifies challenges and opportunities in the process of urban development through analyzing and comparing urbanization pathways of several Asian countries as for representatives. It provides both decision support for China's urban development and management, and scientific support for the sustainable urban development in Asian countries.

This brief explores current research on dynamic spectrum auctions, focusing on fundamental auction theory, characteristics of the spectrum market, spectrum auction architecture and possible auction mechanisms. The brief explains how dynamic spectrum auctions, which enable new users to gain spectrum access and existing spectrum owners to obtain financial benefits, can greatly improve spectrum efficiency by resolving the artificial spectrum shortage. It examines why operators and users face significant challenges due to specialty of the spectrum market and the related requirements imposed on the auction mechanism design. Concise and up-to-date, Dynamic Spectrum Auction in Wireless Communication is designed for researchers and professionals in computer science or electrical engineering. Students studying networking will also find this brief a valuable resource.

This Brief introduces the wireless spectrum market and discusses the current research for spectrum auctions. It covers the unique properties of spectrum auction, such as interference relationship, reusability, divisibility, composite effect and marginal effect, while also proposing how to build economic incentives into the network architecture and protocols in order to optimize the efficiency of wireless systems. Three scenarios for designing new auctions are demonstrated. First, a truthful double auction scheme for spectrum trading considering both the heterogeneous propagation properties of channels and spatial reuse is proposed. In the second scenario, a framework is designed to enable spectrum group secondary users with a limited budget. Finally, a flexible auction is created enabling operators to purchase the right amounts of spectrum at the right prices according to their users dynamic demands. Both concise and comprehensive, Auction Design for the Wireless Spectrum Market is suited for professionals and researchers working with wireless communications and networks. It is also a useful tool for advanced-level students interested in spectrum and networking issues."

This brief focuses on the current research on location privacy preservation in cognitive radio networks (CRNs). Along with a review of the existing works, this book includes fundamental privacy models, possible frameworks, useful performance, and future research directions. It explores privacy preservation techniques, collaborative spectrum sensing, database-driven CRNS, and modeling potential privacy threats. Conflicts between database owners and unlicensed users can compromise location privacy, and CRNs are a means to mitigate the spectrum scarcity issue due to the increasing demand for wireless channel resources. By examining the current and potential privacy threats, the authors equip readers to understand this developing issue. The brief is designed for researchers and professionals working with computer communication networks and cognitive radio networks. Graduate students interested in networks and communication engineering will also find the brief helpful.

Compared with other wireless communication technologies, such as Bluetooth, WiFi, and UWB, ZigBee (R) is a far more reliable, affordable, and energy-efficient option. It is also the only global wireless communication standard for easily deployed, low-power consumption products. ZigBee (R) Network Protocols and Applications provides detailed descriptions of ZigBee network protocols and explains how to set up and develop your own ZigBee-based customized applications with step-by-step instructions. Starting with a brief introduction to near-field communications, low-power communications, and related protocols, it discusses ZigBee architectures, standards, and protocols. It also addresses potential issues such as power management, security, reliability, quality of service, topology control, MAC routing, and transport protocols. Emphasizing development tools that are based on readily available commercial kits, the book illustrates ZigBee applications across a wide range of fields. Each chapter presents the contributions of a different group of experts from around the world. The book is organized into five major parts: Introduces near-field communications (NFC), low-power communications, and ZigBee along with related protocols such as Bluetooth, WiFi, UWB, and Wireless USB Describes ZigBee architectures, standards, and protocols Examines ZigBee performance improvement and addresses potential issues Illustrates ZigBee applications across a range of fields-explaining how to develop ZigBee applications that are based on commercially available kits and hardware Compares and contrasts ZigBee with 6LoWPAN, Z-Wave, Wireless Hart, and RFID Providing step-by-step instruction on how to set up and develop ZigBee-based applications, this book is a must-read for researchers and engineers. Supplying the required foundation and network protocols, it is also s

With the rapid development in the human capabilities to both generate and collect data, the discovery of knowledge from data has become a practical and popular research topic. In this book, the knowledge discovery from data is conducted from two overarching viewpoints: first, developing transparent prediction models from the data that represent input-output relationships using a cooperative fuzzy modelling framework; second, based on these developed models, finding the optimal designs (solutions) to achieve a set of predefined objectives using nature-inspired optimisation algorithms. The theoretical aspects behind these two research facets are described and the associated experimental studies are also carried out. This book is therefore addressed to the researchers and practitioners, who are interested in nature-inspired computation and systems modelling with intelligent systems.
