Abstract Powerful wireless devices carried by humans can form human contact-based networks. Such networks often suffer from intermittent connectivity. Thus, providing an effective information dissemination feature in such networks is very important. In this paper, we explore a cooperative user centric information dissemination scheme which allows published data items to be delivered to interested nodes efficiently. Our scheme uses fewer relays and allows each node to operate distributedly using locally gathered information. Our scheme is more effective than the epidemic scheme since it achieves comparable success ratio with a 45–60\% reduction in storage requirement and 47–53\% reduction in transmissions. We also compare our scheme with an ideal scheme which assumes one can analyze contact traces apriori to determine their dominating sets, and show that our scheme can be more efficient than this ideal scheme.
