Greening Video Distribution Networks: Energy-Efficient Internet Video Delivery

Description

This insightful text presents a guide to video distribution networks (VDNs), providing illuminating perspectives on reducing power consumption in IP-based video networks from an authoritative selection of experts in the field. A particular focus is provided on aspects of architectures, models, Internet protocol television (IPTV), over-the-top (OTT) video content, video on demand (VoD) encoding and decoding, mobile terminals, wireless multimedia sensor networks (WMSNs), software defined networking (SDN), and techno-economic issues. Topics and features: reviews the fundamentals of video over IP distribution systems, and the trade-offs between network/service performance and energy efficiency in VDNs; describes the characterization of the main elements in a video distribution chain, and techniques to decrease energy consumption in software-based VoD encoding; introduces an approach to reduce power consumption in mobile terminals during video playback, and in data center networks using the SDN paradigm; discusses the strengths and limitations of different methods for measuring the energy consumption of mobile devices; proposes optimization methods to improve the energy efficiency of WMSNs, and a routing algorithm that reduces energy consumption while maintaining the bandwidth; presents an economic analysis of the savings yielded by approaches to minimize energy consumption of IPTV and OTT video content services. The broad coverage and practical insights offered in this timely volume will be of great value to all researchers, practitioners and students involved with computer and telecommunication systems.​ Front Matter ....Pages i-xii Video Distribution Networks: Architectures and System Requirements (Adrian Popescu, Yong Yao, Dragos Ilie)....Pages 1-23 Energy-Efficient Management and Control in Video Distribution Networks: ‘Legacy’ Hardware-Based Solutions and Perspectives of Virtualized Networking Environments (Raffaele Bolla, Roberto Bruschi, Franco Davoli, Etienne Victor Depasquale)....Pages 25-57 Video Distribution Networks: Models and Performance (Adrian Popescu, Yong Yao, Markus Fiedler, Xavier Ducloux)....Pages 59-80 Energy-Aware Software Video Encoding in Head-End (Mikko Uitto)....Pages 81-99 Reducing Power Consumption in Mobile Terminals—Video Computing Perspective (Martti Forsell)....Pages 101-126 Software Measurement of Energy Consumption on Smartphones (Thomas Vincent, Olivier Philippot)....Pages 127-132 Energy Efficiency in Wireless Multimedia Sensor Networking: Architecture, Management and Security (Erkki Harjula, Tenager Mekonnen, Miika Komu, Pawani Porambage, Tero Kauppinen, Jimmy Kjällman et al.)....Pages 133-157 Energy-Efficient Routing in SDN-Based Access Networks (Siwar Ben Hadj Said, Alexandre Petrescu)....Pages 159-175 Toward Green SDN Networks (Yannick Carlinet, Nancy Perrot)....Pages 177-202 Estimates of the Economic Impact of Energy Savings in the End-to-End Chain for Video Services (Kinga Pilarska, Bernard Liau, Nancy Perrot)....Pages 203-224 Back Matter ....Pages 225-227
