Opportunistic Networks aim to provide reliable communications in an intermittently connected environment. Most of the existing transmission schemes are taking a class of store-carry-forward schemes to improve the delivery. However, they don't take the social selfish nodes into consideration. To deal with the unpredictability in connections and uncooperative behaviors in the nodes, this paper proposes a transmission scheme to make the social selfish nodes cooperate in forwarding messages for other nodes. In the proposed scheme, a priority is given to a message according to the cooperation degree, a cache management scheme is applied, and a delivery probability is calculated to guide nodes to select the better nodes as its relay. Simulation experiments show that the proposed routing protocol is effective and outperforms the existing routing solutions.
