New Parameters for Measuring Exposure to Diffusion in Dynamic Networks

This paper deals with diffusion processes in dynamic networks. We propose new notions for measuring the exposure of a node to diffusion processes taking place over the network, that is the likelihood of the node to be affected by such processes. We introduce different exposure scores, based either on contacts or on flows in the dynamic network. We study the distribution of these values in the example case of a real-world dynamic network and investigate possible correlations between them. We also discuss computational complexity issues.
