This study aims to explore the tradeoff between sensing capabilities and achievable throughput for secondary users in cognitive radio networks.
Examined the relationship between channel sensing parameters such as probability of detection and false alarm probability.
Utilized energy detection schemes to assess optimal sensing time for secondary users.
Conducted computer simulations to validate the proposed tradeoff methodology.
Found an optimal sensing time that maximizes throughput while sufficiently protecting primary users.
Demonstrated that higher detection probability enhances primary user protection, while lower false alarm rates increase secondary user throughput.
Proved through simulation that cooperative sensing can further improve the sensing-throughput tradeoff.
