Hybrid satellite-terrestrial networks are becoming increasingly popular for asymmetric multimedia services such as file transfer and database services. This paper presents an adaptive error control (AEC) protocol for the hybrid network, in which the transmitter uses a combination of automatic repeat request (ARQ) over terrestrial links and forward error control (FEC) scheme with adaptive code rate over satellite links. Throughput performance shows that the proposed AEC protocol adapts to a time-variant satellite channel better than the static hybrid ARQ protocol under different satellite channel conditions
