On Unicast based Recovery for Multicast Content Distribution considering XOR-FEC

Abstract: In this paper, we propose a fail-safe and efficient download completion scheme for reliable multicast to which FEC (Forward Error Correction) is applied with practical constraints on multicast transmission time. Recently, erasure codes based on XOR operation have become major FEC candidates for multicast content file distribution over the Internet or mobile networks in terms of their recovery performance and processing overheads. In particular LT (Luby Transform) codes are effective in a heterogeneous multicas… Show more

“…Os códigos LT (Luby Transform), propostos por Michael Luby em 2002 [2], foram a primeira implementação do conceito de fontanas digitais (digital fountains) com tempos de codificação e decodificação viáveis em sistemas que requeiram a formação de um grande número de símbolos codificados n, a partir de k símbolos de entrada. Por serem baseados em operações XOR, estes códigos apresentam altas velocidades de codificação e decodificação, além de oferecerem uma promissora capacidade na correção de erros [3]. Os códigos LT foram originalmente concebidos para canais com apagamento, BEC (Binary Erasure Channel), livres de erros.…”
