Abstract-- This paper addresses the problem of streaming
packetized media through a proxy server to a mobile client over
multiple wireless channels. We follow a rate-distortion optimized
streaming approach. A real-time sender-driven streaming frame-
work is employed at the proxy server to maximize the playback
quality at the client. The experimental results show that the
proposed algorithm improves the video quality by 1.3-3dB as
compared to the conventional system which simply transmits the
video data in the order they are displayed.
I. INTRODUCTION
The rapid growth in the number of both Internet and mobile
clients has resulted in developing advanced wireless commu-
nication systems. For example, wireless LAN and the third
generation (3G) wireless systems provide high data rates that
will facilitate a wide variety of applications including real-time
