In high speed environments, the protocol processing overhead at the stations and network nodes becomes a performance bottleneck as the transmission rate increases. Selective repeat (SR) protocols are the most eecient of the automatic repeat request (ARQ) strategies, but present the highest implementation complexity. Techniques such as repeated(More)
This paper proposes and evaluates a point-to-multipoint GB(N) scheme with memory at receivers, suitable for high speed satellite communications. Its key idea is to store errorless messages received during an error recovery procedure It avoids buuer overrow, reduces the round trip delay eeect, is easy to implement and presents a good performance under a wide(More)
