Abstract :
This paper presents an adaptive error control (AEC) scheme for multimedia applications in integrated terrestrial-satellite wireless networks. The AEC protocol supports both real-time and non-real-time applications. In the AEC protocol, we propose new adaptive FEC (AFEC) and hybrid ARQ (HARQ) schemes for real-time and non-real-time traffic, respectively. Throughput performance for non-real-time application shows that the proposed AEC protocol outperforms hybrid ARQ (HARQ) protocols with the same code used. Under real-time application, the AEC protocol outperforms the static FEC (SFEC) protocols with respect to packet miss probability
