Abstract
This paper investigates ARQ operation in a satellite communications system with inter-satellite links. The satellite is considered to have on-board processing (OBP) capability that differs from a conventional bent-pipe satellite system. The inter-link delay is analyzed for OBP ARQ via the technique for signal-flow graph and the result is compared to bent-pipe ARQ both with the Selective-Repeat scheme. A general scenario with multiple inter-satellite links is examined. The effect of buffer blocking to both throughput efficiency and delay are considered. An analytical result indicates that OBP ARQ although having an advantage over bent-pipe ARQ in throughput efficiency suffers in delay due to buffer queueing.
