Abstract
In this paper, a novel video transmission scheme is proposed to meet the low-delay and error-robust requirement of wireless mobile communications. In the proposed scheme, a combination of selective repeat (SR) and stop-and-wait (SW) ARQ (Automatic Repeat reQuest), is adopted at the link layer. In addition, an adaptive FEC (forward error correction) scheme that has a different redundancy rate depending on the number of retransmissions is adopted at the physical layer. The simulation results show that the proposed SR-SW-ARQ/FEC scheme has better performance in terms of video quality and less transmission delay compared with a conventional SSM scheme that has a static redundancy FEC scheme and SW-ARQ protocol.
