In this paper, the authors focus on mobile wireless networks comprising of a powerful communication center and a multitude of mobile users. They investigate the propagation of deadline-based content in the wireless network characterized by heterogeneous (time-varying and user-dependent) wireless channel conditions, heterogeneous user mobility, and where communication could occur in a hybrid format (e.g., directly from the central controller or by exchange with other mobiles in a peer-to-peer manner). They show that exploiting double opportunities, i.e., both time-varying channel conditions and mobility, can result in substantial performance gains.
