Cognitive Radio Networks

2017
A cognitive radio can be defined by the capability of being aware of its environment and the internal state and, based on the knowledge of these elements and any stored pre-defined objectives, can dynamically adapt, make, and implement decisions about its behavior.

Oblivious Rendezvous in Cognitive Radio Networks

2014
Rendezvous is a fundamental process in the operation of a Cognitive Radio Network (CRN), through which a secondary user can establish a link to communicate with its neighbors on the same frequency band (channel). The licensed spectrum is divided into N non-overlapping channels, and most previous works assume all users have the same label for the same ...
