Opportunistic channel access scheme for cognitive radio system based on residual white space distribution
We propose an opportunistic channel access scheme for cognitive radio-enabled secondary networks. In our work, we model the channel occupancy due to Primary User (PU) activity as a...

Multinode Spectrum Sensing Based on Energy Detection for Dynamic Spectrum Access
— Sharing of the frequency spectrum between licensed primary users and unlicensed secondary users (SUs) requires reliable detection of spectrum occupancy by the SUs. Due to fadin...

Pricing-based spectrum access control in cognitive radio networks with random access
Abstract—Market-based mechanisms offer promising approaches for spectrum access in cognitive radio networks. In this paper, we focus on two market models, one with a monopoly pri...
