Opportunistic fountain coding with coordinative routing

Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due to their simple coding mechanisms. In this letter, we propose an opportunistic decoding and recoding mechanism with coordinative routing algorithm for fountain codes to improve the expected...
