Part II Plenary Speeches

TBD Plenary Speech 2: Mobile Device-to-Device Video Distribution: Theory and Application Speaker: Prof. Liang Zhou, Nanjing University of Posts and Telecommunications, China Time: Monday Morning, September 26, 2016 Location: Tongji Room(通济厅), 3rd Floor, Ramada Xi'an Bell Tower Abstract As the video traffic has dominated the data flow of smartphones, traditional cellular communication faces substantial challenges. In this work, we study the mobile device-to-device (D2D) video distribution which leverages the storage and communication capacities of the hand-held smartphones. In such a mobile distributed framework, D2D communication is an opportunistic manner which represents an opportunity to selectively store and transmit local videos to meet the future demand of others. The performance is measured by the service time which denotes the elapsed period for fulfilling the demand, and the corresponding implementation of each device depends on the video's demand, availability, and size. The main contents of this talk lie in: 1) Considering the impact of video size in a practical mobile D2D video distribution scenario, and proposing a general global estimation of the video distribution based on the limited and local observations; 2) Designing the detailed implementation of the distributed video distribution scheme, which does not need to know the video availability, user demand, and device mobility; 3) Validating the proposed video distribution scheme in a practical mobile D2D communication environment.As the video traffic has dominated the data flow of smartphones, traditional cellular communication faces substantial challenges.
