The multiple originator broadcasting problem in graphs

We begin an investigation of broadcasting from multiple originators, a variant of broadcasting in which any k vertices may be the originators of a message in a network of n vertices. The requirement is that the message be distributed to all n vertices in minimum time. A minimumk-originator broadcast graph is a graph on n vertices with the fewest edges such that any subset of k vertices can broadcast in minimum time. B"k(n) is the number of edges in such a graph. In this paper, we present asymptotic upper and lower bounds on B"k(n). We also present an exact result for the case when k=n2. We also give an upper bound on the number of edges in a relaxed version of this problem in which one additional time unit is allowed for the broadcast.
