Cognitive radio has emerged as an efficient approach to implement reuse of the licensed spectrums. How to appropriately deploy and construct the secondary network plays an important role. Several cognitive medium access control (MAC) protocols have been proposed for the secondary users (non-licensed users) to access the underutilized spectrum. In this thesis we consider a secondary user with energy harvesting capability. We design access schemes for the secondary user which incorporate random spectrum sensing and random access. The sensing and access probabilities of the secondary user, are dynamically computed such that the secondary user throughput is achieved is high, under the constraints that the primary queue is stable and that the primary queuing delay is kept low, in order to guarantee a quality of service (QoS) for the primary user.
