A Novel Scheme for Message-Forwarding in Multi-Hop Ad-Hoc Wireless Networks

In this paper, we propose a novel decode-combine-forward scheme for the multi-hop transmission in ad-hoc wireless networks, where the information generated by two independent sources has to be sent to a common destination based on multiple-relay cooperation. The proposed scheme blends together LDPC channel coding with linear combination of blocks of data over a finite field. The performance of the proposed system is compared with two reference schemes previously proposed on the literature. We provide simulation results which show that our scheme clearly outperforms these reference systems.
