Efficient Resource Allocation for Multicell Heterogeneous Cognitive Networks With Varying Spectrum Availability

This paper investigates the problem of designing an efficient spectrum-allocation mechanism in heterogeneous multicell coordinated cognitive radio networks (CRNs) under time-varying channel availabilities and traffic demands across the different cells. The problem is modeled as a utility proportiona...
