Ensuring secure transmission and good quality of service (QoS) in ad hoc wireless networks are key commercial concerns. Focusing on practical potential solutions, this text covers security and QoS in these networks. Starting with a review of the basic principles of ad hoc wireless networking, coverage progresses to vulnerabilities, and the requirements and solutions necessary to tackle them. QoS in relation to ad hoc networks is covered in detail, with specific attention to routing, QoS support in unicast communication, and recent developments in the area. Secure routing, intrusion detection, security in WiMax networks and trust management are also covered, the latter being based on principles and practice of key management and authentication in distributed networks. Representing the state-of-the-art in ad hoc wireless network security, this book is a valuable resource for researchers in electrical and computer engineering, as well as practitioners in the wireless communications industry.

Tagging is fast becoming one of the primary ways people organize and manage digital information. Tagging complements traditional organizational tools like folders and search on users desktops as well as on the web. These developments mean that tagging has broad implications for information management, information architecture and interface design. And its reach extends beyond these technical domains to our culture at large. We can imagine, for example, the scrapbookers of the future curating their digital photos, emails, ticket stubs and other mementos with tags. This book explains the value of tagging, explores why people tag, how tagging works and when it can be used to improve the user experience. It exposes tagging's superficial simplicity to reveal interesting issues related to usability, information architecture, online community and collective intelligence.

Joomla! is life!
It is an open-source project that is in constant motion. It is unpredictable, sometimes indescribable, partially controversial, now and then slightly sleepy, and provincial. Despite this, or perhaps exactly because of this, it has been extremely successful for two years now and is popular with millions of users worldwide.
There is a stable, widely used, and popular version 1.0x. For the past two years, developers have hammered, tinkered, forged, modified, disagreed, deleted, expanded, and hammered again.
Two incredibly exciting years have passed since the foundation of Joomla! 2005.
The Joomla! team has organized and established itself in these years, it has enhanced Joomla! 1.0 up to version 1.0.13 and has now taken the biggest development step so far with version 1.5.
The users of the system have been equally ambitious. Many of them have converted their websites from Mambo to Joomla! And many users have come brand new to Joomla!, and there are still some people in this world that don't know the system.
Joomla! is the most widely used open-source Web Content Management System in the world.
One year after the foundation of the project, in the fall of 2006, the development team reported approximately 5,000,000 Joomla! installations on public web servers that were being used more or less continuously. There were 45,000 registered developers with 1,100 projects that expanded Joomla! with additional functionalities. There were 450,000 entries from 50,000 users in the forum at joomla.org.

Experienced author David Mercer uses a friendly, engaging style that is clear and concise, allowing readers to advance rapidly until they can tackle any problem with confidence. Drupal is an elegantly designed, well-supported and flexible open-source CMS platform that empowers anyone to create a website or blog and is rapidly becoming first choice of people in the know. With this powerful tool you need not pay professionals to design a site; you can do the job yourself.
About the Author
About the Author
David Mercer was born in August 1976 in Harare, Zimbabwe. Having always had a strong interest in science, David came into regular contact with computers at university where he graduated cum laude with majors in applied math and math (although he minored in computer science).
As a programmer and professional writer who has been writing both code and books for about nine years, he has worked on a number of well known titles, in various capacities, on a wide variety of topics. His books have sold tens of thousands of copies and have been translated into over 6 different languages to date.
David finds that the challenges arising from the dichotomous relationship between the science (and art) of software programming and the art (and science) of writing is what keeps his interest in producing books piqued. He will no doubt continue to write professionally in the future.
David balances his time between programming, reviewing, writing, and contributing to interesting web-based projects such as RankTracer and LinkDoozer. When he isn't working (which isn't that often) he enjoys playing guitar (generally on stage and unrehearsed) and getting involved in outdoor activities ranging from touch rugby and golf to water skiing and snowboarding.
