We present an algorithm which, given a tree network and a time, determines a smallest set of subtrees covering sites of the network such that broadcast can be completed within the given time in each subtree. Information developed by the algorithm is sufficient to determine a satisfactory originator and calling scheme within each subtree.enCreative Commons BY-NC-ND 4.0-USGarey and Johnsonlevel-based networkcommunication characteristicsArticlehttps://doi.org/10.1137/0602040
