Video sharing with seamless service handoff in mobile device-centric cloud computing environment

Video sharing traditionally is an upload-then-share process for users. Users upload videos to cloud servers expecting their friends to login and share from these data centers. Therefore, real-time sharing is not possible since prior to the transmission, the uploading requires reformatting and transcoding the video file. This is both energy and time consuming especially that the cloud server is long-distant away while the transmission is through wireless communication. In this paper, we propose a real-time video sharing scheme based on Mobile Device-Centric Cloud (MDC2) computing to meet the requirement of User-Centric Networking (UCN). The experiment shows that video sharing is in real-time and superiorly accommodates rapid context change no matter users share videos across the Internet or not.
