Most of the currently deployed networks are typically dimensioned considering the "peak hour" traffic demand. Opportunistically utilizing these "excess" resources might be an effective way for improving utilization and lowering the "production" costs. This paper is proposing and evaluating a novel concept, called ActiveCast, and the corresponding architecture for a network and user behavior aware mobile content delivery system. When considering real traffic measurements in urban scenarios we showed that the concept improves the resource utilization and allows serving significantly more users in a pre-existing network. Even with moderate amounts of reliable context information, ActiveCast have been shown to drastically improving both user quality of experience perception and network efficiency, as compared to conventional on-demand content delivery schemes.
