Performance Study of an Enhanced Adaptive FEC for Wireless Media Streaming

This paper proposes an enhanced adaptive forward error correction (EAFEC) algorithm based on cross- layer design for wireless media streaming, in the hope that the media could be played on receivers with high quality. This algorithm, which uses the Poisson process to predict the current network condition, can adjust the sending rate of MPEG video frame adaptively and allocate the network bandwidth resource between MPEG video source data and redundant data dynamically. Our mathematical analyses and simulation results show that EAFEC mechanism achieves better quality of media streaming comparing with original FEC, in terms of playable frame rate, reliability and real-time performance on the receiver.
