In this paper, a transmission strategy of fountain codes over cooperative relay networks is proposed. When more than one relay nodes are available, we apply network coding to fountain-coded packets. By doing this, partial information is made available to the destination node about the upcoming message block. It is therefore able to reduce the required number of transmissions over erasure channels,...
We derive the capacity of multicast transmissions on a class of erasure networks. The network model incorporates interference in the form of a finite-field additive multiple-access channel for the receiver on each node, but there is no broadcast constraint (any node can transmit independent symbols on each of its outgoing edges). Assuming knowledge of erasure locations at destination nodes, we derive...
