Lower bounds for distributed algorithms for complete networks of processors (i.e., networks where each pair of processors is connected by a communication line) are discussed. We first show an f2(n log n) lower bound for the number of messages required by any algorithm in a given class of distributed algorithms for such networks. This class includes algorithms for problems like finding a leader ...
