Performance of a hybrid ARQ scheme for partially reliable transport services

Previously, it was shown that provision of reliable transport services in networks which experience loss of packets can be very costly and hence accepting losses up to a certain level might be considered as an alternative approach. Recently, a family of generalised weighted sum codes (GWSC) for erasure correction was discovered which are attractive candidates to support such a partially reliable transmission. In this paper, we present a new partially reliable hybrid ARQ scheme based on GWSC along with performance estimates. The idea can be used with some other non-binary codes too, for example Reed-Solomon codes.
