Cognitive radio (CR) networks can re-use the RF spectrum licensed to a primary user (PU)
network, provided that the interference inflicted to the PUs is carefully controlled. However, …

… This paper will consider the power control problem for the first category, and we focus on …
and the cognitive radio network operate simultaneously. The power control problem becomes …

… Abstract—We propose a robust distributed uplink power allocation algorithm for underlay
cognitive radio networks (CRNs) with a view to maximizing the social utility of secondary users (…

… power control in cognitive radio networks. Different formulations of the IWFA are reviewed,
and the problem is formulated as a robust game to guarantee an acceptable quality of service …

… two important design criteria for cognitive radio networks, ie, to … In this paper, we consider a
cognitive radio network that … We consider the downlink scenario in the cognitive radio network…

… In this paper, we focus on transmission power control. We show that unique features of CR
