Abstract

The scheme of real time streaming video is one of
the newcomers in wireless data communication,
raising a number of new requirements in both
telecommunication and data communication systems.
This scheme is applied when the user experiences real
time multimedia content. Rate control is an important
issue in video streaming applications for both wired
and wireless networks. A widely accepted rate control
method in wired networks is equation based rate
control. In this work, we focus on a mechanism for
equation based congestion control for video
transmission over WCDMA networks. With our
mechanism, the sender explicitly adjusts its sending
rate as a function of the measured rate of loss events,
the round trip time and the packet size. Furthermore,
we examine the performance of UMTS air interface for
real time video transmission using real time protocols,
through a number of experiments.
