    Book SynopsisWritten by experts in the field, this book describes the Personal Network architecture and its various components This book focuses on networking and security aspects of Personal Networks (PNs). Given a single user, the authors propose an architecture for PNs in which devices are divided into one of two types of nodes: personal nodes and foreign nodes. Furthermore, the authors demonstrate the ways in which PNs can be formed in a self-organized and secure way, how they can be interconnected using infrastructure networks, how multiple PNs can be connected, and how their services and resources can be shared. In addition, the book shows how security and ease-of-use can be achieved through automatic configuration and how mobility can be supported through adaptability and self-organization. The motivations for the PN concept, the PN architecture, its functionalities and features, as well as future challenges are covered in depth. Finally, the authors consider the potential applicaTable of ContentsForeword. Preface.

    Book SynopsisDistributed source coding is one of the key enablers for efficient cooperative communication. The potential applications range from wireless sensor networks, ad-hoc networks, and surveillance networks, to robust low-complexity video coding, stereo/Multiview video coding, HDTV, hyper-spectral and multispectral imaging, and biometrics. The book is divided into three sections: theory, algorithms, and applications. Part one covers the background of information theory with an emphasis on DSC; part two discusses designs of algorithmic solutions for DSC problems, covering the three most important DSC problems: Slepian-Wolf, Wyner-Ziv, and MT source coding; and part three is dedicated to a variety of potential DSC applications. Key features: Clear explanation of distributed source coding theory and algorithms including both lossless and lossy designs.

    Book SynopsisWritten from an operator's viewpoint, HSPA Performance and Evolution explores the lessons learned and techniques developed for optimally deploying HSPA (High Speed Packet Access). The essential distinctions between rolling out HSPA compared to earlier UMTS and GSM technologies are explained covering the many issues that must be specifically handled. Areas in standards which have been left open for interpretation, causing significant differences between vendor implementations, are identified and solutions explored. This book is invaluable in enabling wireless operators to extract maximum performance offered by 3GPP's HSPA radio technology, consisting of both downlink (HSDPA) and uplink (HSUPA) elements. It focuses on real-world performance, sharing practical implementation methods and tradeoffs for deploying, optimizing and maintaining networks using the HSPA air interface. Examines algorithms, equipment and performance perspectives to identify and explain HSPATable of ContentsFigures and Tables. About the Authors. Preface. Foreword.

    10 in stock

    Book SynopsisWhat makes teamwork tick? Cooperation matters, in daily life and in complex applications. After all, many tasks need more than a single agent to be effectively performed. Therefore, teamwork rules! Teams are social groups of agents dedicated to the fulfilment of particular persistent tasks. In modern multiagent environments, heterogeneous teams often consist of autonomous software agents, various types of robots and human beings. Teamwork in Multi-agent Systems: A Formal Approach explains teamwork rules in terms of agents'' attitudes and their complex interplay. It provides the first comprehensive logical theory, TeamLog, underpinning teamwork in dynamic environments. The authors justify design choices by showing TeamLog in action. The book guides the reader through a fascinating discussion of issues essential for teamwork to be successful: What is teamwork, and how can a logical view of it help in designing teams of ageTrade Review "In sum, the prospective contribution of this book is expected to have an impact on a number of aspects that revolve around the modeling and simulation of teamwork, both from theory and application issues. Therefore, I recommend it to researchers in computer sciences, organization theory and social psychology who are interested in collective thinking, collaborative work and organizational phenomena, as well as to practitioners who deal everyday with the challenge of managing teams in many different settings."

    Book SynopsisThis book explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations With the roll-out of LTE, high data throughput is promised to be available to cellular users. In case you have ever wondered how high this throughput really is, this book is the right read for you: At first, it presents results from experimental research and simulations of the physical layer of HSDPA, WiMAX, and LTE. Next, it explains in detail how measurements on such systems need to be performed in order to achieve reproducible and repeatable results. The book further addresses how wireless links can be evaluated by means of standard-compliant link-level simulation. The major challenge in this context is their complexity when investigating complete wireless cellular networks. Consequently, it is shown how system-level simulators with a higher abstraction level can be designed such that their results still match link-level simulations.

    Book SynopsisA hands-on tutorial on multicast in third-generation networks! In this book, the authors describe how to perform multicast, the one-to-many delivery of data to a group of destinations, in third-generation mobile networks. The authors provide an overview of the services that can be realized with multicast in third-generation networks, describe the mechanisms required to support these services and highlight the performance of several multicast mechanisms.

    Book SynopsisA modern mobile phone is a highly complex electronic system made up from a variety of diverse sub-systems, all of which must work seamlessly together. Today''s users have very high expectations which set tough demands on manufacturers as they introduce third generation technology. While quality, in terms of the phone''s stability, performance and behaviour on the network, originate from good design, the only way to be sure of quality is by testing it. This makes testing a very important part of any mobile phone''s life cycle, from development through to manufacture and beyond, touching a number of different disciplines and departments. Testing UMTS is divided in three sections. Section One provides an overview of major types of testing and the organisations and tasks involved. In particular it looks at what is involved in conformance testing and device certification. Section Two is more technical and looks at the UMTS standard itself, working through the protocol layers.
