Paper Abstract

In this paper, we investigated the possibility and effectiveness of applying ARQ schemes to the transmission of MPEG-2 encoded video streams over fixed wireless links in B- FWANs in video-on-demand services. Simulations were conducted to evaluate the overall system performance, which is then compared to a scheme using FEC with cell interleaving. Important metrics relevant to the broadband video services are analyzed, including the quality of the reconstructed video sequences, the excess delay and delay variation introduced by the ARQ scheme, the throughput, and the required average channel bandwidth. A hidden Markov model was also introduced to model the variation of the wireless channel.
