  4. Abstract:
  5. We present sufficient conditions for multicasting a set of correlated sources over cooperative networks. We propose a joint source-Wyner-Ziv encoding/sliding-window decoding scheme, in which each receiver considers an ordered partition of the other nodes. For each ordered partition, we obtain a set of feasibility constraints . We consolidate the results of the different ordered partitions by utilizing a result of geometrical approach to obtain the sufficient conditions. We observe that these sufficient conditions are indeed necessary conditions for Aref networks. As a consequence of the main result, we obtain an achievable rate region for networks with multicast demands. Also, we deduce an achievability result for two-way relay networks, where two nodes want to communicate over a relay network. © 2009 IEEE
