We consider power control in cognitive radio networks where secondary users identify and exploit instantaneous and local spectrum opportunities without causing unacceptable interference to primary users. We qualitatively characterize the impacts of the transmission power of secondary users on the occurrence of spectrum opportunities and the reliability of opportunity detection. Based on a Poisson model of the primary network, we quantify these impacts by showing that (i) the probability of…

Cognitive Network Interference
TLDR
This work proposes a new statistical model for aggregate interference of a cognitive network, which accounts for the sensing procedure, secondary spatial reuse protocol, and environment-dependent conditions such as path loss, shadowing, and channel fading, and demonstrates the effectiveness of this model in evaluating the system performance of cognitive networks.
A game-theoretic approach to energy-efficient power control in cognitive wireless networks
TLDR
Numerical simulations confirm the theoretical results on the existence and uniqueness of the Nash equilibrium, and show that secondary users have a beneficial impact on the whole network throughput, at the price of a moderate degradation in the performance of the primary users.
Distributed Power Control for Cognitive User Access based on Primary Link Control Feedback
TLDR
It is shown that the PU feedback information inherent in many two-way primary systems can be used as important coordination signal among multiple SUs to distributively achieve a joint performance guarantee on the primary receiver's quality of service.
Connectivity of cognitive radio networks: proximity vs. opportunity
TLDR
The tradeoff between proximity (the number of neighbors) and the occurrence of spectrum opportunities is revealed by studying the impact of secondary users' transmission power on the connectivity region of thesecondary network, and the transmission power of the secondary users is designed to maximize their tolerance to the primary traffic load.
Power allocation in heterogeneous networks: Limited spectrum-sensing ability and combined protection
TLDR
A low-complexity joint power-optimizing method to maximize the transmission rate between CUs, taking into account both the individual power-transmission constraints and the combined interference power constraint of the PUs is proposed.

TLDR
A new simple stochastic geometric model is proposed that captures the salient interdependencies amongst spatially distributed primary and secondary nodes in a cognitive network where licensed primary users and unlicensed but ‘cognitive’ secondary users share spectrum.
Distributed Power Control With Robust Protection for PUs in Cognitive Radio Networks
TLDR
This work studies SUs' power control problem in a non-cooperative game where each SU selfishly maximizes its own throughput performance subject to coupled interference constraints at PU receivers and proposes an iterative algorithm for SUs to achieve the equilibrium in a distributed manner.
A Game-Theoretic Approach to Energy-Efficient Power Control and Receiver Design in Cognitive CDMA Wireless Networks
TLDR
Numerical simulations confirm the theoretical results on the existence and uniqueness of the Nash equilibrium, confirm the effectiveness of the results obtained through the large system analysis, and show that secondary users have a beneficial impact on the whole network throughput, at the price of a moderate degradation in the performance of the primary users.

TLDR
The overall end-to-end communication has been achieved by the use of three kinds of channels occupying four spectrum bands since multiple transmissions may happen simultaneously in cognitive radio relay channel (CRRC).
A game theoretic approach for robust power control in cognitive radio networks
TLDR
This paper practically considers that SUs have only partial knowledge about the channel gains from SUs to PUs, based on which SUs estimate the worst-case channel gains and decide transmit power to robustly protect PUs.
