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.

"[W]ill be welcomed by students of comparative slavery. . . . [It] makes us reconsider the significance of slavery in the subcontinent." —Edward A. Alpers, UCLADespite its pervasive presence in the South Asian past, slavery is largely overlooked in the region's historiography, in part because the forms of bondage in question did not always fit models based on plantation slavery in the Atlantic world. This important volume will contribute to a rethinking of slavery in world history, and even the category of slavery itself. Most slaves in South Asia were not agricultural laborers, but military or domestic workers, and the latter were overwhelmingly women and children. Individuals might become slaves at birth or through capture, sale by relatives, indenture, or as a result of accusations of criminality or inappropriate sexual behavior. For centuries, trade in slaves linked South Asia with Africa, the Middle East, and Central Asia. The contributors to this collection of original essays describe a wide range of sites and contexts covering more than a thousand years, foregrounding the life stories of individual slaves wherever possible.Contributors are Daud Ali, Indrani Chatterjee, Richard M. Eaton, Michael H. Fisher, Sumit Guha, Peter Jackson, Sunil Kumar, Avril A. Powell, Ramya Sreenivasan, Sylvia Vatuk, and Timothy Walker.
