Cognitive Radios (CR) are designed to dynamically reconﬁgure their transmission and/or reception parameters to utilize the bandwidth efﬁciently. With a rapidly ﬂuctuating radio environment, spectrum management becomes crucial for cognitive radios. In a Cognitive Radio Ad Hoc Network (CRAHN) setting, the sensing and transmission times of the cognitive radio play a more important role because of the decentralized nature of the network. They have a direct impact on the throughput. Due to the tradeoff between throughput and the sensing time, ﬁnding optimal values for sensing time and transmission time is difﬁcult. In this thesis, a method is proposed to improve …
