The weighted-vertex broadcast model is an extension of the original model of broadcasting to the graphs with weighted vertices. A vertex of weight ω is supposed to wait for ω time rounds before sending data to its neighbors; after this delay, in each round, it can inform one of its neighbors with no additional delay. We consider the problem in complete weighted-vertex graphs, and introduce a set of properties which describe a class of optimum solutions. Based on these, we present an algorithm which gives optimum broadcast schemes in polynomial time.
