In Mobile Social Networks (MSNets), data dissemination is very important, which has not been widely investigated yet. Active data dissemination is a networking paradigm where a superuser intentionally facilitates the connectivity in the network. One of the key challenges is how to design the most efficient superuser route to achieve certain properties of end-to-end connectivity. Most existing solutions only focus on the network with stationary users or strongly constrained node mobility, and assume the superuser always moves with a fixed route. In this paper, the authors propose a flexible approach to design the superuser routes, considering the realistic user movements in MSNets.
