This book describes a communication paradigm that could shape
the future of wireless communication networks, Opportunistic
Spectrum Access (OSA) in Cognitive Radio Networks (CRN). While
several theoretical OSA approaches have been proposed, they are
challenged by the practical limitations of cognitive radios: the
key enabling technology of OSA. This book presents an unprecedented
formulation of the OSA problem in CNR that takes into account the
practical limitations encountered due to existing technologies.
Based on such a problem formulation, this book presents a framework
and protocol details implementing the analytically-optimized
solution of this problem. Unlike the state-of-the-art of CRN
implementations that typically target software define radios which
are not suitable for real systems, this book describes the
implementation of distributed OSA, using practical radio
transceiver technologies. It provides a thorough characterization
of the gains available to theoretical OSA approaches if the
practical limitations are taken into consideration.
Tackles the cognitive radio networks performance optimization
problem, taking into account the practical limitations of today s
technologies;Provides thorough performance evaluation in arbitrary,
large-scale networks, as well as microscopic, small-scale
performance evaluation, using realistic hardware
implementation;Presents an empirical study of the gains available
over existing techniques by adopting practical approaches;Tackles
