Performance Evaluation of a Hybrid FEC/ARQ for Wireless Media Streaming

Abstract

This paper proposes a link-level hybrid FEC/ARQ based on an adaptive forward error correction (adaptive FEC) algorithm for wireless media streaming, in the hope that the media could be played on receivers with high quality. This model, which uses adaptive forward error correction mechanism at the application layer to adjust to the current network condition, can maximize the performance of wireless multimedia communication. Our simulation results and mathematical analysis show that the hybrid FEC/ARQ achieves better quality of media streaming comparing with FEC alone and ARQ alone, in terms of playable frame rate, reliability and real-time performance on the receiving side.

Performance Analysis of an Adaptive Hybrid FEC/ARQ Based on Hops for Wireless Multimedia Sensor Networks

“…As a result, we obtain the maximum number of playable frames and improve the reliability performance. The analysis results shows that our approach can yield better performance of multimedia applications in WMSNs than existing approaches (ARQ [6], FEC [7] and hybrid FEC/ARQ (H-FEC/ARQ) [2]). …”

“…The influence of the information from the data link layer on the quality of video transmission is not concerned in [1]. The characteristic of Hops of link layer frames is not mentioned in [2] [3]. The reliability and realtime performance of media streaming transmission is not mentioned in [4], their focus is on long-lived TCP traffic.…”

“…Z. MEI et al analyzed the structure of video stream, and presented a frame decoding model that takes into account the frame types and the dependence among frames in [1]. In [2], [3] [4] and [5], hybrid FEC/ARQ method was adopted. The number of data retransmission is limited to restraint the delay for improving the quality of transmission.…”

“…Some error control mechanisms for the application layer have been proposed in the literatures [1][2][3][4][5]. Z. MEI et al analyzed the structure of video stream, and presented a frame decoding model that takes into account the frame types and the dependence among frames in [1].…”

A High Energy Efficiency Link Layer Adaptive Error Control Mechanism for Wireless Sensor Networks

“…Some error control mechanisms for the high layer of WSNs have been proposed in the literatures [3][4]. However, many researches show that a poor error control mechanism at the data link layer may also degrade the performance of WSNs significantly.…”
