Coexistence of macrocells and small cells sharing the same spectrum represents a special case of cognitive networking, where small cells and their users ca

However, most designs of cooperative sensing strategies are developed in a rather ad hoc manner due to the lack of the fundamental knowledge on the cooperation gain. Hence, in this chapter, the cooperation

Focusing on the eavesdropping attack, a secrecy problem of the communication between a secondary transmitter-receiver pair in the presence of randomly distributed eavesdroppers is specifically investigated. The dynamic transmit power control is adopted a

Adaptive Learning in Cognitive Radio,s a brief introduction to a variety of machine-learning techniques. The basic setup of machine learning, as well as the dichotomy, is explained. Then, the supervised, unsupervised, semi-supervised, and reinforcement learning techniques are briefly discussed. The single-agent learning is then extende

Autonomous Spectrum Sharing by Well-Designed Games,trum holes or “white spaces,” we have witnessed many changes all over the world regarding how spectrum is being allocated. The message is clear, and that spectrum allocation needs to be more dynamic and adaptive to the environment and applications. However, dynamic spectrum sharing and access is com
