Efficient and fair power allocation associated with congestion control in orthogonal
frequency division multiplexing (OFDM)-based multi-hop cognitive radio networks (CRNs) is …

The overall performance of multi-hop cognitive radio networks (MHCRNs) can be improved
significantly by employing the diversity of orthogonal licensed channels in underlay fashion …

In this paper, a resource allocation algorithm in two-way orthogonal frequency division
multiplexing (OFDM) based cognitive radio networks with quality of experience (QoE) and …

In this paper, we investigate the energy-efficient resource allocation in orthogonal frequency
division multiplexing (OFDM)-based cognitive radio (CR) networks, where we try to …

In this paper, we study resource allocation for a multicarrier-based cognitive radio (CR)
network. More specifically, we investigate the problem of secondary users' energy-efficiency …

In this paper, we study the coexistence and optimization of a multicell cognitive radio
network (CRN) which is overlaid with a multicell primary radio network (PRN). We propose a …

In this paper, we investigate the robust power allocation issue in orthogonal frequency
division multiplexing-based cognitive radio networks (CRNs) with unavoidable uncertainties …

Interference due to the sharing of common spectrum band among links and congestion due
to the contention among flows sharing the same link have become obstacles to good …

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 …

In this paper we consider resource allocation for an OFDMA-based cognitive radio point-to-
multipoint network with fixed users. Specifically, we assume that secondary users are …
