Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the current research on the dynamic spectrum sharing for efficient spectrum resource utilization, which covers the overlay spectrum sharing, underlay spectrum sharing and database-assisted spectrum sharing related research issues. Followed by a comprehensive review and in-depth discussion of the current state-of-the-art research literature and industry standardization, this book first presents a novel overlay spectrum sharing framework for dynamic utilization of available cellular frequency bands, formulates the dynamic spectrum sharing problem as a dynamic resource demand-supply matching problem, and accordingly develops a distributed fast spectrum sharing algorithm to solve the resource matching problem. A self-awareness power control approach for multi-hop routing selection is proposed, which can establish an effective and practical routing selection optimization in secondary access networks and minimize the interference to primary users. Finally, this book offers dynamic secondary access scheme for database-assisted spectrum sharing networks, which is targeted to support the prosperous wireless multimedia networking applications by leveraging the TV white spaces of geolocation databases while satisfying QoS guarantees of secondary users. The overlay spectrum sharing, underlay spectrum sharing, and database-assisted white spaces spectrum sharing research results that are presented in this book provide useful insights for the design of next generation wireless access networks. This book motivates a new line of thinking for efficient spectrum resource utilization and performance enhancements of future wireless access applications.

Download or read book Multimedia over Cognitive Radio Networks written by Fei Hu and published by CRC Press. This book was released on 2014-12-04 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: With nearly 7 billion mobile phone subscriptions worldwide, mobility and computing have become pervasive in our society and business. Moreover, new mobile multimedia communication services are challenging telecommunication operators. To support the significant increase in multimedia traffic—especially video—over wireless networks, new technological infrastructure must be created. Cognitive Radio Networks (CRNs) are widely regarded as one of the most promising technologies for future wireless communications. This book explains how to efficiently deliver video, audio, and other data over CRNs. Covering advanced algorithms, protocols, and hardware-/software-based experiments, this book describes how to encode video in a prioritized way to send to dynamic radio links. It discusses different FEC codes for video reliability and explains how different machine learning algorithms can be used for video quality control. It also explains how to use readily available software tools to build a CRN simulation model. This book explains both theoretical and experimental designs. It describes how universal software radio peripheral (USRP) boards can be used for real-time, high-resolution video transmission. It also discusses how a USRP board can sense the spectrum dynamics and how it can be controlled by GNU Radio software. A separate chapter discusses how the network simulator ns-2 can be used to build a simulated CRN platform.

Download or read book Opportunistic Spectrum Access Using Localization Techniques written by Ahmed O. Nasif and published by . This book was released on 2009 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scarcity of radio spectrum poses a significant challenge to the sustained growth of wireless communications, since most of the useful radio spectrum is already allocated for licensed users. However, recent spectrum measurement studies have shown that there are plenty of white spaces or spectrum holes that could be utilized opportunistically by "secondary" users, provided that they do not cause harmful interference to the primary users. In this dissertation, we develop efficient methods by which a group of secondary users equipped with cognitive radios can determine and access spectrum holes opportunistically based on signal measurements. The cognitive radios are frequency-agile in that they can dynamically tune to different frequency channels for transmission and reception. By ex- changing signal strength measurements, a group of cognitive radios can calculate maximum likelihood estimates of the location and transmit powers of the primary transmitters in the system. We apply the Cramer-Rao bound (CRB) to characterize the error in the primary system parameter estimates. The parameter and error estimates are then used to derive an approximation to the Maximum Interference-Free Transmit Power (MIFTP), which is the maximum allowable power that a given cognitive radio can use on a given frequency channel subject to an interference constraint. To mitigate interference from multiple cochannel primary transmitters, secondary nodes maintain a distributed database that records the location, power, and error estimates of cochannel nodes for each frequency channel. The proposed MIFTP approximation takes into account errors in spectrum sensing such that the approximation becomes more conservative when measurement errors accrue, and conversely, it becomes more accurate when better measurement data is available. The property of being conservative is important, since secondary users must avoid causing harmful interference to primary users. We also propose two model identification and measurement clustering criteria to identify the number of cochannel primary transmitters and to cluster the measurements appropriately for more accurate estimation of the primary system parameters. Finally, we extend the proposed opportunistic spectrum techniques to incorporate angle-of-arrival information for improved localization accuracy and hence tighter estimates for the MIFTP.
