Randomly Select and Forward: Erasure Probability Analysis of a Probabilistic Relay Channel Model

Free registration required

Executive Summary

This paper proposes a semi-analytical framework for estimating the erasure probability in single-hop multi-relay networks. Specifically, the authors consider a system, in which relays do not decode the information but simply forward coded packets that have been previously received from the source. This allows for uncoordinated, low-complexity processing at the relays. They present a detailed analysis of the proposed network model, which represents an instance of a new coding scheme that they refer to as distributed fountain coding.
