Abstract: In this paper we investigate three channel allocation algorithms for multi-channel cognitive radio networks: SNR-based allocation (SA), queue-based allocation (QA), and queue-based SNR-aware allocation (QSA). The efficiency of the proposed algorithms is investigated for VoIP… read more here.
