Paper Abstract:
|
This paper proposes a mechanism for the congestion control for video transmission over UMTS. Our scheme is applied
when the mobile user experiences real time multimedia content and adopts the theory of a widely accepted rate control
method in wired networks, namely equation based rate control. In this approach, the transmission rate of the multimedia
data is determined as a function of the packet loss rate, the round trip time and the packet size and the server explicitly
adjusts its sending rate as a function of these parameters. Through a number of simulations and experiments we validate
the correctness and measure the performance and efficiency of the mechanism. The mechanism at first level is evaluated
through simulations that carried out in the ns-2 simulator. At second level, in order to validate the proposed mechanism
in real world traffic scenarios we perform some experiments in a commercial UMTS network. |
