Optimal opportunistic sensing in cognitive radio networks
The authors are interested in evaluating the performance of a Cognitive Radio (CR) network composed of Secondary Users (SUs) and Primary Users (PUs). We look for optimizing the decision process of the secondary mobiles when they have to choose between licensed or unlicensed channels. In fact, the system is composed of several channels where only one unlicensed channel is shared between all the ...
متن کاملOpportunistic Scheduling in Cognitive Radio Networks
We develop opportunistic scheduling policies for cognitive radio networks that maximize the throughput utility of the secondary (unlicensed) users subject to maximum collision constraints with the primary (licensed) users. We consider a cognitive network with static primary users and potentially mobile secondary users. We use the technique of Lyapunov Optimization to design an online flow contr...
متن کاملEfficient radio resource management algorithms in opportunistic cognitive radio networks
Cognitive radio (CR) paradigm was introduced, towards addressing challenges, related with radio spectrum scarcity and increased needs for wireless networking services provision. In this direction, CR networks exploit novel networking architectures, as well as dynamic radio spectrum access techniques and methods, alleviating problems, regarding limited wireless networking resources and their ine...
متن کاملSense-and-Predict: Harnessing Spatial Interference Correlation for Opportunistic Access in Cognitive Radio Networks
Cognitive radio (CR) is a key enabler realizing 5G networks to achieve higher spectral efficiency by allowing spectrum sharing between different wireless networks. It is important to explore whether spectrum access opportunities are available, but conventional CR based on transmitter (TX) sensing cannot be used to this end because the paired receivers (RXs) may experience different levels of in...
