Advances in wireless technologies promise to reshape the way we conduct business. Yet to make wireless e-business work effectively, a variety of enabling technologies are needed. Kou and Yesha and their contributors provide comprehensive information on these technologies, including, for example, wireless security, mobile payment, location-based services, mobile data management, and RFID technologies. The presentation is targeted at students, lecturers, e-business developers, consultants, and business managers, and this book is an ideal introduction for both self-study and taught e-business classes or commercial training courses. “I believe this is an excellent book to acquire comprehensive knowledge on enabling technologies for the blooming wireless e-business. I highly recommend this book!” Robert Mayberry, Vice President, Sensors and Actuators, IBM Software Group

Cross-layer design seeks to enhance the capacity of wireless networks significantly through the joint optimization of multiple layers in the network, primarily the physical (PHY) and medium access control (MAC) layers. Although there are advantages of such design in wireline networks as well, this approach is particularly advantageous for wireless networks due to the properties (such as mobility and interference) that strongly affect performance and design of higher layer protocols. This unique monograph is concerned with the issue of cross-layer design in wireless networks, and more particularly with the impact of node-level multiuser detection on such design. It provides an introduction to this vibrant and active research area insufficiently covered in existing literature, presenting some of the principal methods developed and results obtained to date. Accompanied by numerous illustrations, the text is an excellent reference for engineers, researchers and students working in communication networks.

An international panel of experts provide major research issues and a self-contained, rapid introduction to the theory and application of UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas:

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.

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus deliver its most encompassing and pervasive accomplishment to mankind, promptly taking care of the needs and wishes of everyone.
Or maybe not. The described evolution is driven primarily by market forces and vastly ignores the users’ intentions. Yet the recent history of the Internet has shown that these intentions can have devastating effects; for example, spam, viruses, “phishing” and denial of service attacks have unfortunately become commonplace. The misbehavior of a relatively small number of users is leading to a substantial inconvenience to the whole community. Similar or even worse misdeeds are and will be perpetrated in wireless networks.

Inside, you’ll find 150+ practice exam questions with complete answers, step-by-step exercises, chapter self-tests, margin notes, and much more to help you prepare for this challenging exam.

Among network designers and administrators, wired Ethernet is a known quantity. Plenty is known about how to build good twisted-pair network infrastructures, how to keep them secure, and how to monitor their excess capacity. Not so for the wireless Ethernet networks (built around the IEEE 802.11x standards)–these hold much more mystery for even experienced network designers. 802.11 Wireless Networks: The Definitive Guide aims to codify the body of knowledge needed to design and maintain wireless local area networks (LANs). The authors succeed admirably in this, covering what installation and administration teams need to know and digging into information of use to driver writers and others working at lower levels.The only significant detail that’s been excluded has to do with security–a notorious weak point of 802.11x LANs. The authors cover the feeble but widely used Wired Equivalent Privacy (WEP) authentication protocol in detail and devote another whole chapter to 802.1x, which is an emerging authentication scheme based on Extensible Authentication Protocol (EAP). The author has considerable skill in communicating information graphically and does a great job of using graphs to show how communications frequencies shift over time and how conversations among access points and network nodes progress over time. This is indeed an authoritative document.

WCDMA (Wideband Code Division Multiple Access), an ITU standard derived from code division multiple access (CDMA) is officially known as IMT-2000 direct spread. WCDMA is a third generation mobile wireless technology offering much higher data speeds to mobile and portable wireless devices than commonly offered in today’s market.  WCDMA is a relatively new technology and there is little information in the public domain about specific design issues. The proposed book will discuss UMTS/WCDMA from the perspective of a potential development engineer, who may have experience of GSM but none of WCDMA technology. The book will outline the design specifications and potential problems and solutions faced by by an engineer designing a mobile device such as a handset.

With the arrival of IEEE 802.11b (a.k.a. WiFi) and other wireless networking technologies on the market comes a wave of stories about snoops intercepting sensitive LAN traffic from out in the company parking lot or across the concourse at the airport. Hack Proofing Your Wireless Network takes a look at strategies for defending wireless LANs–those based on Bluetooth and IEEE 802.11a as well as WiFi–against signal interception and other attacks peculiar to their wireless nature. Unfortunately, there's also a lot of background information on WiFi (as well as on security principles in general), and this is related to wireless network security only tangentially. Though this material represents unneeded padding, the bulk of the book is made up of useful information about security strategies and defensive configuration. There's also a fair bit of information about the security characteristics of some top-selling wireless networking products. In a section on choosing WiFi access points, the authors give a very explicit list of requirements (the ability to disable service-set identifier broadcasts, 128-bit Wired Equivalent Protocol–WEP–and so on), and list at least three real products (by make and model) that fit the specifications. They then proceed to show how to choose the most secure configuration options on each of the featured products, including the Cisco Systems Aironet and the Agere ORiNOCO. Configuration instructions are easy to follow and illustrated in detail. Information on the offensive side of the equation is shallower–the authors point out that it's possible to drive around, looking for unsecured wireless access points and that WEP has security flaws. Still, this book is one of the first on security for wireless networks, and it provides a lot of good information to the administrators of such networks

From entertainment to telephony, emerging wireless systems will make possible a new generation of wireless multimedia applications. To satisfy users, network designers and developers must integrate end-to-end Quality of Service (QoS) support throughout all their underlying networks: WANs, WLANs, WPANs, and "last-mile" WLL or satellite distribution systems. However, wireless network standards typically focus on signaling, leaving crucial QoS issues to implementers. Multimedia Wireless Networks is the first book to help network professionals systematically address QoS in today's most important wireless networks — and tomorrow's.
