The authors investigate traffic-grooming problems in optical WDM mesh networks from various aspects. They cover static and dynamic traffic grooming, as well as grooming policies for both environments. A fundamental graph model for traffic-grooming networks is proposed. A variety of grooming-node architectures are examined and their performances compared. Design of traffic-grooming networks using different node architectures is explored, and traffic grooming in next-generation SONET/SDH networks is presented.

This is the first book dedicated to cognitive radio, a promising new technology that is poised to revolutionize the telecommunications industry with increased wireless flexibility. Cognitive radio technology integrates computational intelligence into software-defined radio for embedded intelligent agents that adapt to RF environments and user needs. Using this technology, users can more fully exploit the radio spectrum and services available from wireless connectivity. For example, an attempt to send a 10MB e-mail in a zone where carrier charges are high might cause a cognitive radio to alert its user and suggest waiting until getting to the office to use the LAN instead. Cognitive Radio Architecture examines an “ideal cognitive radio” that features autonomous machine learning, computer vision, and spoken or written language perception.

“…a very good explanation of an interesting topic…the overview of SIP is excellent…a call flow explains the complex sequence of events very well…” (Computer Bulletin, September 2002)
“This book is like a good tour guide.It doesn’t just describe the major attractions; you share in the history, spirit, language, and culture of the place.”
