This book provides an overview of the latest research and development of
new technologies for cognitive radio, mobile communications, and
wireless networks. The contributors discuss the research and requirement
analysis and initial standardization work towards 5G cellular systems
and the capacity problems it presents. They show how cognitive radio,
with the capability to flexibly adapt its parameters, has been proposed
as the enabling technology for unlicensed secondary users to dynamically
access the licensed spectrum owned by legacy primary users on a
negotiated or an opportunistic basis. They go on to show how cognitive
radio is now perceived in a much broader paradigm that will contribute
to solve the resource allocation problem that 5G requirements raise. The
chapters represent hand-selected expanded papers from EAI sponsored and
hosted conferences such as the 12th EAI International Conference on
Mobile and Ubiquitous Systems, the 11th EAI International Conference on
Heterogeneous Networking for Quality, Reliability, Security and
Robustness, the 10th International Conference on Cognitive Radio
Oriented Wireless Networks, the 8th International Conference on Mobile
Multimedia Communications, and the EAI International Conference on
Software Defined Wireless Networks and Cognitive Technologies for IoT.
