A classical result in undirected wireline networks is the near optimality of routing (flow) for multiple-unicast traffic (multiple sources communicating independent messages to multiple destinations): the min cut upper bound is within a logarithmic factor of the number of sources of the max flow. In this paper, we extend the wireline result to the wireless context. In particular, we show the following meta-theorem: if for a given channel and its reciprocal channel, the cut-set bound is… CONTINUE READING
