Energy-Efficient transmission strategies with multiple radios in cognitive radio: Beyond rendezvous
(Institute of Electrical and Electronics Engineers Inc., 2018)
Cognitive radio (CR) has emerged as a key technology to deal with the frequency spectrum scarcity. The efficient and opportunistic use of the spectrum requires rapid coordination between the secondary users (SUs). Besides, ...

(Universidade Federal de UberlândiaBRPrograma de Pós-graduação em Engenharia ElétricaEngenhariasUFU, 2016)
Algorithm and software based on MLPNN for estimating channel use in the spectral decision stage in cognitive radio networks
The use of the multilayer perceptron neural networks (MLPNN) technique is proposed to estimate the future state of use of a licensed channel by primary users (PUs); this will be useful at the spectral decision stage in ...
Dynamic spectrum management : from cognitive radio to blockchain and artificial intelligence
Radio spectrum, as an indispensable enabler of wireless communications, is
becoming a severely scarce resource with the explosive growth of wireless traffic
and massive connections of devices. Because of the spectrum ...
A Cognitive Way to Access the Frequency Spectrum
(2013-07-05)
Cognitive radio (CR) is an emergent technology in wireless communication. It aims at improve considerably spectrum use by allowing dynamic spectrum access (DSA). The DSA can be performed in different ways, e.g. interweave ...
Hyper Secure Cognitive Radio Communications in an Internet of Space Things Network Based on the BB84 Protocol
(Institute of Electrical and Electronics EngineersPE, 2020-11-11)
Once constellation of satellites are working in a collaborative manner, the security of their messages would have to be highly secure from all angles of scenarios by which the praxis of eavesdropping constitutes a constant ...
