This paper proposes a novel method to provide a selective VoD service in live streaming environment using peer-to-peer communications. The proposed scheme defines a peer classification method and a video frame sharing method to decrease peer side traffic burden. The proposed scheme can decrease the peer generating traffic overhead compared to the conventional peer-to-peer live streaming protocol.
The ballbot with arms is an underactuated balancing mobile robot that moves on a single ball. Achieving desired motions in position space is a challenging task for such systems due to their unstable zero dynamics. This paper presents a novel approach that uses the dynamic constraint equations to plan shape trajectories, which when tracked will result in optimal tracking of desired position trajectories...
