Opportunistic Fountain Coding With Coordinative Routing

Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due their simple coding mechanisms. In this letter, we propose an opportunistic decoding recoding mechanism with coordinative routing algorithm for fountain the expected transmission counts (ETX) performance reduce computational complexity of at each relay multi-hop sensor networks. The full recovery existing cooperative coded networks is replaced by a new partial which both recovered unrecovered packets intermediate nodes considered as candidates. Numerical results show that proposed superior routing-based code schemes.
