Dual-Level Sensing Based Multiple Access Protocol for Cognitive Radio Networks

In this paper, we improve throughput performance of a cognitive radio network through a proposed dual-level sensing strategy. Throughput performance of secondary users cannot be enhanced while providing higher priority to protect primary users from secondary user interference. Therefore, we propose...

Summary:In this paper, we improve throughput performance of a cognitive radio network through a proposed dual-level sensing strategy. Throughput performance of secondary users cannot be enhanced while providing higher priority to protect primary users from secondary user interference. Therefore, we propose a novel multiple access scheme based on dual-level sensing strategy by which both the interference protection and the throughput enhancement can be accomplished. We propose a dual-level sensing regime within the short sensing period to explore higher transmission opportunities and then utilize the sensing outcome to reduce the collision during the multiple access phase. Performance evaluation shows that the proposed scheme improves the throughput of the secondary users and guarantees the primary user protection during multiple access.
