In the floating content application, mobile nodes collectively store and disseminate messages relevant to a certain area by using the principles of opportunistic networking. The system operates in best effort fashion relying solely on the nodes located in the area of interest, which is referred to as the anchor zone of the message. Past work has focused on mobility models, where the nodes are constantly moving and the messages are exchanged "On-the-fly". In this paper, the authors consider the case, where messages can be exchanged only when two nodes are stationary within each others' transmission range. Their objective is to characterize when the information floats, that is, when it is likely to remain available for long periods of time.
