Abstract: Opportunistic networks utilize the communication opportunities arising from node movement to forward messages. So the reliability of message transmission between nodes is non-guaranteed and depends on the intermediate nodes. However, in most cases, the intermediate nodes of a network are resource-constrained or capability-restricted, so these nodes are selfish and do not want to supply storing and forwarding service for other nodes. In this paper, we propose a scheme to discourage the selfish behavior based on the reputation. Moreover, we build a game theory model to analyze the effectiveness of our scheme. The experiment results show that the proposed scheme indeed stimulates the cooperation of nodes.
