| Abstract(in English) | In this paper, we propose a robust multicast communication system in wireless multihop networks. In the proposed system, source nodes encode information packets with Reed-Solomon erasure correcting code, which is implemented in application layer and transmit the coded packets into the network. Intermediate nodes in the network encode received packets with linear network coding, which is implemented in network layer. While Reed-Solomon code add redundancy to information packets, network coding reduces the number of relayed packets in the network. Therefore, the proposed system provides highly efficient and robust multicast communication. We further propose a new decoding mechanism which combines the parity matrix of Reed-Solomon code and the coding matrix of linear network coding. With the decoding mechanism, destination nodes decode received packets as soon as they receives a fraction of packets. |
