Adaptive and reliable video transmission over UMTS for enhanced performance

چکیده
This paper proposes a mechanism for the congestion control for video transmission over universal mobile telecommunications system (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. Furthermore, we examine the performance of the UMTS for real-time video transmission using real-time protocols. Through a number of experiments, we measure performance parameters such as end-to-end delay, delay in radio access network, delay jitter and throughput in the wireless link.

Performance Enhancement of Real-Time Video Communications over UTRAN by Adaptive Resource Allocation: System Level Evaluation
In this paper, a novel adaptive resource allocation algorithm for video services over UTRAN is proposed. The proposed algorithm deploys joint spreading gain control and transmission power allocation to enhance the performance of real-time video communications over time-varying errorprone environments. The proposed algorithm operates in two phases. In the first phase, adaptation is conducted bas...

The focus of this paper is end-to-end reliable transmission in UMTS environment where TCP, a reliable tranport protocol designed to retransmit information in case of loss, is present at the mobile station as well as the wired portion of the network. The mobile and wireless portion of the network, characterized by significant error figures, relies on ARQ to detect and retransmit corrupted frames...
متن کاملMultiple Description Video Coding for Umts
We consider the problem of efficient real time video transmission over UMTS channels. Such a problem involves good compression rates and effectiveness in presence of channel failures. We propose a balanced MDC scheme for 3D scan-based DWT video coding. This MDC includes an efficient bit allocation procedure that dispatches the source video redundancy between the different channels[1, 2]. We pro...
