An Adaptive H-ARQ Strategy Based on the Types of Business in Aerospace Information Network
This paper deals with the application of H-ARQ techniques to reliable end-to-end data communications with adaptive adjustment of parameters according to the type of business in aerospace information network, whose applications have to cope with accurate Quality-of-Service (QoS) requirements. In the adaptive H-ARQ strategy, we adopt cell-level RS code as Forward Error Correction (FEC) coding scheme. Retransmissions of the corrupted data block are combined at the receiver with the previously received sequences of the same data block for decoding. Particularly, adaptive adjustment of FEC coding parameters and ARQ retransmission times by the type of business joint the state of network. As a result, it has been possible to allow each business a better QoS, in terms of error rate, throughput, and delivery delay.
