This paper studies content dissemination (narrowcasting) in wireless ad hoc networks. We consider (i) the dissemination of general (non selective, broadcast) content (ii) with loose delay constraints (iii) aimed at an entire community confined in a restricted area (iv) served periodically by one single and stationary content emitter (i.e., an access point). These constraints target challenging environments where for practical and/or economical reasons content dissemination must be set up on the fly with the least effort. Examples are dissemination of information at a conference, in military operations, to team workers, and to inhabitants of remote villages. Based on real-world mobility traces, we analyze different dissemination strategies comparing cooperative versus non-cooperative behavior of nodes for storing and/or forwarding content. In particular, we evaluate how the performance is impacted by mobility. The main outcome is that node collaboration drastically increases the performances of content dissemination while the per-device overhead (or load) is very low and remains on average evenly distributed.
