Multi-Source Network Coding

In Chapter 11, we have discussed the single-source network coding problem in which an information source is multicast in a point-to-point communication network. The maximum rate at which information can be multicast has a simple characterization in terms of the maximum flows in the graph representing the network. In this chapter, we consider the more general multi-source network coding problem in which more than one mutually independent information sources are generated at possibly different nodes, and each of the information sources is multicast to a specific set of nodes. We continue to assume that the point-to-point communication channels in the network are free of error.
