Scalable Video Streaming Over Wimax Networks

This book offers a comprehensive explanation on how to dimension, plan, and optimize WiMAX networks. The first part of the text introduces WiMAX networks architecture, physical layer, standard, protocols, security mechanisms, and highly related radio access technologies. It covers system framework, topology, capacity, mobility management, handoff management, congestion control, medium access control (MAC), scheduling, Quality of Service (QoS), and WiMAX mesh networks and security. Enabling easy understanding of key concepts and technologies, the second part presents practical examples and illustrative figures to explain planning techniques and optimization algorithms. The author provides both theoretical and practical information to ensure in-depth, realistic results.

This book constitutes the refereed proceedings of the 8th International Conference on Wired/Wireless Internet Communications, WWIC 2010, held in Luleå, Sweden, in June 2010. The 17 revised full papers were carefully reviewed and selected from 45 submissions. The papers are thematically grouped into 5 technical sessions such as cooperation and multimedia traffic management in WN, advances to IEEE 802.11, routing and performance optimization, security, control and signalling, as well as wireless sensor networks.

The book is about all aspects of computing, communication, general sciences and educational research covered at the Second International Conference on Computer & Communication Technologies held during 24-26 July 2015 at Hyderabad. It hosted by CMR Technical Campus in association with Division – V (Education & Research) CSI, India. After a rigorous review only quality papers are selected and included in this book. The entire book is divided into three volumes. Three volumes cover a variety of topics which include medical imaging, networks, data mining, intelligent computing, software design, image processing, mobile computing, digital signals and speech processing, video surveillance and processing, web mining, wireless sensor networks, circuit analysis, fuzzy systems, antenna and communication systems, biomedical signal processing and applications, cloud computing, embedded systems applications and cyber security and digital forensic. The readers of these volumes will be highly benefited from the technical contents of the topics.

The area of video streaming has seen tremendous growth in recent years due to the enhanced processing power, better compression algorithms, and increased bandwidths in emerging networks. Most of the latest communication standards are IP based, whereas the Internet provides only a best-effort service model and the priority-based service models are only gradually being realized for real-time data. Current research attempts to overcome the effects of video packet losses and delays to provide a better user experience. Multimedia communication over wireless channels is especially difficult due to the fact that the channel conditions are generally poor, in addition to the rapid changes that can occur in the channel. Fountain codes can address some of the challenges in this research area, and can also be combined in innovative ways with the different importance classes of compressed video data. Considering the importance of the issues highlighted above, this book focuses on designing error correction techniques to exploit different importance classes in compressed video data for designing adaptive solutions to support multimedia traffic over wireless channels. This book represents a useful reference point for researchers, academics, research students, and industry developers interested in utilizing error correction codes for ensuring better video quality.

Multimedia Quality of Experience (QoE) Current Status and Future Requirements Multimedia Quality of Experience (QoE): Current Status and Future Requirements discusses the current status of QoE (Quality of Experience) research, providing guidelines on QoE assessment and management practice. Moreover, it covers many different aspects of QoE research, including definitions, standardization (ITU, ETSI, IEEE, IETF), measurement, management, and architectures. In addition, the authors bring together contributions from recognized experts (worldwide) in the area of subjective and objective QoE video assessment. Discusses the current status of QoE research; reporting the latest advances from various standardization bodies Provides guidelines on QoE assessment and management practice Explores methods, means, and architectures of QoE Considers future requirements of QoE

Exchange of information and innovative ideas are necessary to accelerate the development of technology.
