The authors consider a cost model for diffusion in a network that captures both the scope of infection and its propagation time: the edges of the network have associated lengths which model transmission times, and influence scores are higher for faster propagation. They propose an intuitive measure of timed influence, which extends and unifies several classic measures, including the well-studied \"Binary\" influence (which only measures scope), a recently-studied threshold model of timed influence (which considers a node influenced only within a fixed time horizon), and closeness centrality (which is extended from being defined for a single node to multiple seed nodes and from a fixed network to distributions).
