Download or read book Opportunistic Spectrum Sharing in Cognitive Radio Networks written by Zhe Wang and published by Springer. This book was released on 2015-03-18 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Springer Brief investigates spectrum sharing with limited channel feedback in various cognitive radio systems, such as point-to-point, broadcast scheduling and ad-hoc networks. The design aim is to optimally allocate the secondary resources to improve the throughput of secondary users while maintaining a certain quality of service for primary users. The analytical results of optimal resource allocation are derived via optimization theory and are verified by the numerical results. The results demonstrate the secondary performance is significantly improved by limited feedback and is further improved by more feedback bits, more secondary receivers and more primary side information.

Download or read book Machine Learning Based Spectrum Decision in Cognitive Radio Networks written by Koushik Araseethota Manjunatha and published by . This book was released on 2018 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cognitive radio network (CRN) is considered as one of the promising solutions to address the issue of spectrum scarcity and eective spectrum utilization. In a CRN the Secondary User (SU) is allowed to occupy the spectrum which is temporarily not used by the Primary User (PU). Frequent interruptions from the PUs is the fundamental issue in CRN. The interruption forces SU to perform hando to another idle channel. On the other hand, spectrum hando can occur due to the mobility of the node. Hence, CRNs needs a smart spectrum decision scheme to timely switch the channels. An important issue in spectrum decision is spectrum hando. Since the SU's spectrum usage is constrained by the PU's trac pattern, it should carefully choose the right hando time. To increase the overall performance of the SU in the long term we use several machine learning algorithms in spectrum decision and compare it with the myopic decision which tries to achieve maximum performance in the short run.
