Mobility Support in User-Centric Networks

In this paper, an overview of challenges and requirements for mobility management in user-centric networks is given, and a new distributed and dynamic per-application mobility management solution is presented. After a brief summary of generic mobility management concepts, existing approaches from the distributed and peer-to-peer mobility management literature are introduced, along with their applicability or shortcomings in the UCN environment. Possible approaches to deal with the decentralized and highly dynamic nature of UCNs are also provided with a discussion and an introduction to potential future work

Transmission of 3D Video Content

International audienceThis chapter describes different video transport technologies that support the existing 3D video formats, such as frame-compatible side-by-side and multi-view video plus depth. Particular emphasis is given to the DVB systems (terrestrial, satellite, and cable) and IP transport, focusing HTTP/TCP streaming, adaptive HTTP streaming, RTP/UDP streaming, P2P Networks, and Information-Centric Networking-ICN. Hybrid transport technologies, combining broadcast and broadband networks for video delivery are also addressed. The chapter highlights important aspects of 3D video transmission over wireless networks, together with their benefits and limitations in the delivery of this type of content. Recent research results are summarized for different delivery systems and transport technologies
