The authors present sufficient conditions for multicasting a set of correlated sources over cooperative networks. They propose joint source-Wyner-Ziv encoding/sliding-window decoding scheme, in which each receiver considers an ordered partition of other nodes. Subject to this scheme, they obtain a set of feasibility constraints for each ordered partition. They consolidate the results of different ordered partitions by utilizing a result of geometrical approach to obtain the sufficient conditions. They observe that these sufficient conditions are indeed necessary conditions for Aref networks. As a consequence of the main result, they obtain an achievable rate region for networks with multicast demands.
