Paper Abstract

MPEG streaming over Mobile Internet leads to degradation of MPEG video quality. When a handoff of a mobile node (MN) occurs, it is quite difficult to guarantee seamless video quality due to the change of routing path towards the MN. In this paper, we propose a new scheme, MPEG streaming over Concatenation and Optimization for Reservation Path (CORP), to guarantee QoS of MPEG streaming service in the Mobile Internet. When a handoff of a MN occurs, the CORP extends the existing reservation path, which was established using RSVP between a server and a MN, to a new Base Station (BS) that the MN currently connected to, instead of making a new RSVP session between the server and the MN. To demonstrate practicality of the proposed scheme, we built a prototype system which provides the MPEG-1 Video and Audio on demand over Mobile Internet using Mobile IP and IEEE 802.11b wireless LAN. Our experiment shows that the proposed scheme significantly improves the peak signal-to-noise rate (PSNR) of MPEG streaming video. Also, we analyzed the video quality of our scheme with respect to TCP and UDP transport protocols.
