This innovative new book explains how GPRS (general packet radio service) allows you to expand your GSM networks towards third generation mobile communications to meet the demands of the most-sophisticated mobile data applications. The book concentrates on the interfaces between the known GSM network elements and the new subsystems -- PCU, SGSN, and GGSN -- that come with GPRS. It offers you an in-depth explanation of the extensions and methods of the GSM air interface necessary for GPRS and shows how the channel-oriented GSM is linked to the packet switched GPRS. Moreover, it explains what extensions there are in channel coding, how resources are allocated on the air interface, and how the quick network access necessary for GPRS is made possible.

This invaluable reference gives you the ability to easily and rapidly penetrate typical design and operation issues of GPRS. It enables you to understand the differences between the various 2.5 G extensions of GSM, gives you a firm grasp of the implications of mobile data services and how they differ from regular speed services, and clearly conveys the distinction between circuit-switched and packet-switched technologies. The book also addresses alternative bandwidth configurations, HSCSD and EDGE, and the TCP/IP protocols now used in GSM. They conclude with a detailed description of the various scenarios of GPRS and HSCSD, all of which are of great value to the professional in daily work.

Companion website features three appendices: Components of CRE, Introduction to Medium Access Control and Elements of Queueing Theory

This book covers what an administrator needs to plan out and integrate a DMZ into a network for small, medium and Enterprise networks. In most enterprises the perception is that a firewall provides a hardened perimeter. However, the security of internal networks and hosts is usually very soft. In such an environment, a non-DMZ system that is offering services to the Internet creates the opportunity to leapfrog to other hosts in the soft interior of your network. In this scenario your internal network is fair game for any attacker who manages to penetrate your so-called hard perimeter.

- There are currently no books written specifically on DMZs
- This book will be unique in that it will be the only book that teaches readers how to build a DMZ using all of these products: ISA Server, Check Point NG, Cisco Routers, Sun Servers, and Nokia Security Appliances.
- Dr. Thomas W. Shinder is the author of the best-selling book on Microsoft's ISA, Configuring ISA Server 2000. Customers of the first book will certainly buy this book.

This book explores the fundamental concepts, basic theory, and key principles of 802.11 networks with roaming capabilities. Today, we increasingly expect to find public Wide Local Area Network (WLAN) 802.11 access in our airports, public spaces, and hotels, and we want to maintain our connections when we're mobile and using 802.11 WLANs.

However, 802.11 was not originally designed with roaming capabilities and can't, in its "pure" form, support seamless roaming between different hotspots and other 802.11 access points. This book details the theory behind various 802.11 extensions to permit roaming and describes how these extensions can be successfully implemented in 802.11 WLANs. Coverage of User Authentication in 802.11 is reviewed as is roaming between 802.11 and other wireless technologies. Wireless technologies and application programming interfaces are given their due with generous coverage as well.

* Offers a comprehensive treatise on Wi-Fi 802.11 roaming by comparing/contrasting it to cellular roaming theory and techniques
* Emerges as a "one stop" resource for design engineers charged with fulfilling the market need for seamless 802.11 device roaming capabilities
* Builds upon the knowledge base of a professional audience without delving into long discussions of theory long since mastered

With modern communication networks continuing to grow in traffic, size, complexity, and variety, control systems are critical to ensure quality and effectively manage network traffic. Providing a thorough and authoritative introduction, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control examines the theory, architectures, and technologies needed to implement quality of service (QoS) in a wide variety of communication networks.

Based on years of research and practical experience, this book examines the technical concepts underlying the design, implementation, research, and invention of both wired and wireless networks. The author builds a strong understanding of general concepts and common principles while also exploring issues that are specific to wired, cellular, wireless ad hoc, and sensor networks. Beginning with an overview of networks and QoS control, he systematically explores timely areas such as Lyapunov analysis, congestion control of high-speed networks, admission control based on hybrid system theory, distributed power control of various network types, link state routing using QoS parameters, and predictive congestion control. The book also provides a framework for implementing QoS control using mote hardware.

Providing a deeply detailed yet conveniently practical guide to QoS implementation, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control is the perfect introduction for anyone new to the field as well as an ideal reference guide for seasoned network practitioners.
