Mobile device-controlled live streaming traffic transfer for multi-screen services

With the rapid increase in multimedia content and various screen devices, mobile users want to watch content regardless of device type anytime and anywhere, which is called multi-screen service (MSS), performed by service mobility technology. Although existing research studies support service mobility and MSS, they do not take into account inter-domain scenarios and live streaming services. In this paper, we propose mobile device-controlled service transfer (MDST) mechanism, which mobile device is allowed to transfer this service to target device first-hand. To support our mechanism, we extend the service discovery protocol in DLNA and present service flow-based mobility at the mobile device. In addition, we analyze the performance of the proposed mechanisms and confirm that MDST is superior in terms of signaling cost, packet delivery cost, and service disruption delay cost.
