Abstract

We prove that in order to communicate independent sources (this is the\nunicast problem) between various users over an unknown medium to within various\ndistortion levels, it is sufficient to consider source-channel separation based\narchitectures: architectures which first compress the sources to within the\ncorresponding distortion levels followed by reliable communication over the\nunknown medium. We are reducing the problem of universal rate-distortion\ncommunication of independent sources over a network to the universal reliable\ncommunication problem over networks. This is a reductionist view. We are not\nsolving the reliable communication problem in networks.\n
